Where does the 'top banana' / 'second banana' hierarchy come from?

Episode 213: Banana Hierarchy · October 10, 2026 (01:36)
Our guess
Show-business or clown slang from the 1930s; others said 1950s office culture or the banana bunch growing order
Reveal the answer
The answer
Burlesque and vaudeville: comedians were billed as first, second and third bananas, and Phil Silvers credited Harry Steppe with introducing the term around 1927. 'Top banana' later became slang for any boss.
Verdict right

Why is a toilet called 'the head', and why 'hit' it?

Episode 212: Long-Time, First-Time · September 26, 2026 (00:33)
Our guess
A nautical term, from the toilet being at the front of the ship
Reveal the answer
The answer
Ship toilets were at the bow (the 'head'), since the wind from the stern carried waste away; 'head' for the bow dates to 1485 and its use for the toilet is in print by 1708 (Woodes Rogers).
Verdict right

Is it 'toe the line' or 'tow the line', and where does it come from?

Episode 207: Ring of Fire · July 18, 2026 (01:08)
Our guess
Toe, from the foot at the starting line in track and field or the military
Reveal the answer
The answer
'Toe the line' is correct; 'tow' is a common misspelling. First print is from the British Army (1738 'The Army Regulator'), with other theories including the Royal Navy, bare-knuckle boxing and school.
Verdict right

Why is a quick, intensive class called a 'crash course'?

Episode 205: Get Out There, Kid! · June 20, 2026 (00:35)
Our guess
Aviation or military, WWI or WWII era
Reveal the answer
The answer
First noun use is in the 1940s (1949 Washington Post), likely from 'crash program' or 'crash landing' in aviation and military training; the education sense appeared in the 1950s.
Verdict right

Where does 'soup to nuts' come from?

Episode 202: Since Fire and Water · May 9, 2026 (00:31)
Our guess
The first and last courses of a meal (Joey), or nuts and bolts / industrial revolution (Harper, Coalson)
Reveal the answer
The answer
Soup is the first course and nuts the last; the Roman 'ab ovo usque ad mala' (eggs to apples) is a predecessor. The specific phrase 'soup to nuts' is American, from the early 1900s.
Verdict right

Where does the phrase 'like the dickens' come from?

Episode 201: Please, God, Blind Me · April 25, 2026 (00:42)
Our guess
A softened substitute for 'the devil', from the 1600s, popularized by Charles Dickens
Reveal the answer
The answer
A minced oath, a euphemism for 'devil', used by Shakespeare in The Merry Wives of Windsor (c. 1600); it predates Charles Dickens.
Verdict right

Is a buzzard the same as a vulture, and what is a condor?

Episode 200: Eat. Prey. Love. · April 11, 2026 (00:33)
Our guess
Buzzards are smaller, browner and different from vultures; condors are just very big vultures
Reveal the answer
The answer
In the US, buzzards are hawk-like raptors that hunt live prey while vultures eat carrion; in the UK 'buzzard' is a hawk and vultures are sometimes also called buzzards. Every condor is a vulture; the Andean condor is the largest vulture species.
Verdict right

Where does 'playing hooky' come from?

Episode 198: Hide and Seek · June 14, 2025 (00:39)
Our guess
Something Dutch or American, from the early 1900s era of truant officers
Reveal the answer
The answer
19th-century New York City slang, likely from the Dutch 'hoekje' (hide-and-seek, or a nook to hide in); it appears in a 1848 dictionary of Americanisms as schoolboy slang for playing truant.
Verdict right

Where does 'throw your hat in the ring' come from?

Episode 195: Read-Option Father · May 3, 2025 (01:09)
Our guess
Probably boxing (a challenger throwing in a hat), with Shakespeare-era guesses on timing
Reveal the answer
The answer
Boxing: contestants literally threw hats into the ring to join the fight (London Morning Chronicle, 1804). Figurative use is attested in 1820, and Teddy Roosevelt made it a political phrase in 1912.
Verdict right

Where does 'last ditch effort' come from?

Episode 194: No First Ditches · April 19, 2025 (00:42)
Our guess
Trench warfare (the last defensive ditch), with aviation and farming/flooding as alternates
Reveal the answer
The answer
From William of Orange's 17th-century vow to defend the Dutch Republic to the death, 'to die in the last ditch'; it caught on around 1900 as a phrase for a final attempt.
Verdict right

Is chili a soup or a stew?

Episode 190: Viscosity · August 24, 2024 (00:40)
Our guess
A stew, because it's thicker and cooked down rather than liquid-based.
Reveal the answer
The answer
Technically a stew: soup is liquid-based (ingredients submerged), while stew is thicker with just enough liquid to cover the ingredients. Chili is often considered a type of stew, with Tex-Mex origins.
Verdict right

Where does the word "damnedest" (as in "try your damnedest") come from?

Episode 188: From the Marlowe Collection · January 20, 2024 (00:41)
Our guess
Trying so hard you'd risk being damned, perhaps Shakespeare, or a homespun Appalachian phrase from the early 1800s.
Reveal the answer
The answer
"Damn" (from Latin "damnare", to condemn) became an intensifier, and "damnedest" as a superlative is first recorded about 1828-1830 (some sources say 1596), with a colloquial American flavor.
Verdict right

What does "on tenterhooks" mean, how is it spelled, and where does it come from?

Episode 186: Big Circus · January 6, 2024 (01:07)
Our guess
A tent-related hook or a precariously hanging, vulnerable state; spelled "tinder hooks" or "tender hooks".
Reveal the answer
The answer
It's "tenterhooks": hooks on a "tenter", a wooden frame used since the 14th century to stretch wet woolen cloth to dry. From the 18th century "on tenterhooks" meant in suspense, like cloth held stretched. "Tenter" is from Latin "tendere" (to stretch).
Verdict right

Why do dogs wag their tails?

Episode 185: Artificially Evolved · December 16, 2023 (00:31)
Our guess
Nonverbal communication, plus balance, temperature regulation, hygiene or swimming (rudder).
Reveal the answer
The answer
Mainly communication of excitement and mood, and tails also help with balance, temperature regulation (blood vessels) and swimming. A 2013 Current Biology study found dogs wag more to the right when relaxed or happy and more to the left when stressed or anxious.
Verdict right

Where does the phrase "grab the brass ring" come from?

Episode 184: Two For the Price of Three · September 30, 2023 (01:10)
Our guess
A championship ring or trophy in sports, a retirement watch, or a mafia ring; or possibly carousels.
Reveal the answer
The answer
It comes from carousels, where riders reaching out from the horses tried to grab a brass ring from an arm for a free ride. It means a very desirable prize, and has appeared in dictionaries since the late 19th century (and in Catcher in the Rye).
Verdict right

Why are daytime dramas called "soap operas"?

Our guess
Soap ads in 1950s-60s daytime TV aimed at housewives, or soapboxes; "opera" for the melodrama.
Reveal the answer
The answer
They originated in radio dramas sponsored by soap manufacturers, such as Procter & Gamble, starting in the early 1930s (Painted Dreams on WGN in 1930, Guiding Light in 1937). The term followed "horse opera" for low-budget westerns.
Verdict right

What is the difference between a groundhog and a woodchuck?

Episode 182: Whistle Pig · September 10, 2023 (01:06)
Our guess
They are the same animal, or perhaps regional variations, with groundhogs different from prairie dogs.
Reveal the answer
The answer
There is no difference: they are the same animal (Marmota monax, a marmot). "Woodchuck" comes from the Algonquian word "wuchak" and has nothing to do with chucking wood. Groundhog Day was brought by German settlers in Pennsylvania, who used hedgehogs in Germany.
Verdict right

Why are the Buffalo Bills named the Buffalo Bills?

Episode 181: Person-Sized Bison · September 2, 2023 (02:25)
Our guess
A play on Buffalo Bill the showman, named in the 1960s, since "Buffalo Bisons" would be redundant.
Reveal the answer
The answer
The name came from a naming contest for Buffalo's All-America Football Conference team (originally the Bison); owner James Burrell liked a writer's comparison of the team to a band of "Buffalo Bills" after William "Buffalo Bill" Cody, the showman born in Iowa in 1846 who founded Buffalo Bill's Wild West in 1883.
Verdict right

Where does the term "spitballing" come from?

Episode 179: Armed with Care Bear Stare · August 19, 2023 (02:02)
Our guess
The baseball spitball pitch in the early 1900s, or a wad of paper shot through a straw.
Reveal the answer
The answer
It comes from baseball's spitball pitch (MLB banned it in 1911), though earlier uses exist: an 1794 Connecticut ad for a "spitball" for blacking shoes and 1830s kids' paper wads, which weren't used figuratively until the early 1900s.
Verdict right

Is it "baited breath" or "bated breath", and where does it come from?

Episode 176: Pre-Gog · June 24, 2023 (00:35)
Our guess
"Baited" like a bait hook, or "bated" from abatement (stopping), probably Latin or Shakespeare.
Reveal the answer
The answer
It's "bated breath", meaning held or reduced, short for "abated", and it appears in Shakespeare's The Merchant of Venice. "Baited" is a common misspelling, and "bated" is now used almost only in this phrase.
Verdict right

Where does the phrase "sick as a dog" come from?

Episode 170: Money Talks · February 4, 2023 (01:19)
Our guess
Dogs vomit a lot, or dogs on ships were seasick; from the 1500s-1600s, possibly Shakespeare or Rome.
Reveal the answer
The answer
Dogs were considered an undesirable animal in 17th-century England and many phrases used them negatively ("dog tired", "dirty dog"). "Sick as a dog" refers to vomiting, with the earliest literary use in 1705 (some find 1592).
Verdict right

Where does the phrase "whatever floats your boat" come from?

Episode 169: Archimedean · January 14, 2023 (01:09)
Our guess
A 1970s party saying, though perhaps a 1680s exploration or Archimedes-era phrase about water.
Reveal the answer
The answer
It first appears in the early 1980s in magazines and newspapers, derived from earlier phrases like "whatever suits you" (1820s) and 1970s variants like "whatever turns you on", with a sexual connotation.
Verdict right

Why is raising a glass called a "toast"?

Episode 167: Cooked Bread · December 24, 2022 (00:06)
Our guess
Bread and wine were connected early on, possibly from bread cooked and added to drinks, with Shakespeare or Romans involved.
Reveal the answer
The answer
In the 16th century a piece of spiced, scorched toast was commonly put in wine to soften bad flavor and stale bread. Shakespeare's The Merry Wives of Windsor has "put a toast in it", and drinking someone's health as a "toast" is recorded among 18th-century university students. Toastmasters appeared in the 17th and 18th centuries.
Verdict right

What do AM and PM stand for, and where does the 12-hour clock come from?

Episode 166: Fancy Ovens · December 3, 2022 (01:44)
Our guess
Ante meridiem and post meridiem (before and after noon), Latin from Roman times.
Reveal the answer
The answer
AM is Latin "ante meridiem" and PM is "post meridiem". The Egyptians divided the day into 24 parts in base 12 (sundial by day, water clock at night), and the Romans also used 12-hour divisions. The terms are first recorded in English in 1563.
Verdict right

Why do weddings need witnesses, and where does that come from?

Episode 164: So Much Goat Transfer · November 19, 2022 (01:34)
Our guess
To prove the marriage happened for legal or tax purposes as church authority moved to the state, probably from the 1800s or early 1900s, perhaps from ancient Roman times.
Reveal the answer
The answer
Ancient Roman law required ten witnesses at a wedding (a precursor to the bridal party). Medieval marriages were contracts between families; the Church required banns in 1215, and Massachusetts started marriage licenses in 1639. Witnesses help prevent fraud and elopement against family approval.
Verdict right

How can there be seedless fruit, and how does it reproduce?

Episode 158: Mommy and Daddy Trees · September 17, 2022 (00:39)
Our guess
Crossbreeding and genetic engineering produce seedless fruit, and clones keep the plants going.
Reveal the answer
The answer
Seedless grapes began as a natural mutation (known since ancient Rome) and fruit plants are propagated from cuttings or grafting, so they are genetic clones. Seedless watermelons are triploid (three sets of chromosomes) from crossing a diploid with a tetraploid, which makes them unable to reproduce.
Verdict right

Why is a "toboggan" both a sled and a knit hat?

Episode 157: Northern France · September 10, 2022 (01:09)
Our guess
From an Algonquin word, French Canadian or an American Indian term for a sled, with the hat named for it.
Reveal the answer
The answer
"Toboggan" (a sled) is from the Canadian French "tabagane" from Algonquin (Mi'kmaq), recorded in 1829. The hat is short for "toboggan cap", worn while tobogganing; by 1929 the second word was dropped in the American South, where snow is rare.
Verdict right

Where does the phrase "the jig is up" come from?

Episode 156: Elongated Jig · September 3, 2022 (00:05)
Our guess
From the dance, a lively jig ending, or maybe "the gig is up" in 1920s film noir.
Reveal the answer
The answer
"Jig" was Elizabethan slang for a trick or practical joke (16th-century, about 1590), so "the jig is up" means the trick has been exposed. The first documented use is 1777, and "gig is up" is a later variation.
Verdict right

Where does the term "nutmeg" (passing the ball through a defender's legs) come from?

Episode 155: Singing Mouse · August 27, 2022 (06:07)
Our guess
A euphemism for passing through the "nuts", with the spice name as a polite substitute, from the 1970s.
Reveal the answer
The answer
The earliest known use is in a 1977 book by Brian Glanville about the language of football, where the "nuts" are the testicles of a player through whose legs the ball is passed. Another theory is that unscrupulous exporters mixed wooden fake nutmegs into shipments.
Verdict right

Where does the phrase "pull yourself up by your bootstraps" come from?

Episode 154: Satirical or Idiotic · August 20, 2022 (00:30)
Our guess
Originally satirical, describing something impossible, later flipped into meaning self-reliance; likely from the 1800s-1930s.
Reveal the answer
The answer
It was originally used mockingly for an impossible act: a late-1800s physics textbook asks why a man cannot lift himself by pulling up on his bootstraps. It was sarcastic in the early 1900s (Booker T. Washington referenced it in 1895, Joyce in 1922), and the meaning later shifted to self-reliance. A Baron Munchausen story involves pulling oneself from a swamp by his hair.
Verdict right

Where do "10-4" and "Roger" (for "understood") come from?

Episode 152: Animal with a Gun · August 6, 2022 (01:05)
Our guess
Military or police radio codes from World War II, with "Roger" from Morse code's "R" for received.
Reveal the answer
The answer
"10-4" is one of the 10-codes created by the Illinois State Police's communications director Charles Hopper between 1937 and 1940 for police radio. "Roger" is from the WWII phonetic alphabet for R ("received"), which came from the Morse habit of replying with the letter R.
Verdict right

Why is a rice cooker cup a different size from a measuring cup?

Episode 151: No Pressure · July 30, 2022 (02:35)
Our guess
The rice cooker's "cup" is really a scoop or a metric-based unit, translated as "cup", perhaps from Japan.
Reveal the answer
The answer
A rice cooker cup is about 180 ml, while a US cup is about 240 ml. The rice cooker uses a traditional Japanese measure (similar in volume to a sake cup), so the two are not interchangeable.
Verdict right

When and why did we start celebrating birthdays?

Episode 148: Half Crown · July 9, 2022 (03:22)
Our guess
Ancient Egypt's pharaohs, maybe the Romans or Greeks, as a feast day for elites.
Reveal the answer
The answer
The earliest reference is to a pharaoh's birthday (Genesis 40; pharaohs were thought to become gods when crowned). The Greeks added candles for the moon goddess Artemis, and the Romans were first to celebrate commoners (a cake for men turning 50). Candles were thought to ward off evil spirits.
Verdict right

What does "with a bullet" mean (as in on the charts), and where does it come from?

Episode 146: I'll Never Smile Again · June 18, 2022 (00:35)
Our guess
A song shooting up the charts like a bullet, or a bullet point marking a ranking.
Reveal the answer
The answer
From the music trade magazine Cashbox, which put a red bullet next to chart positions of songs making sharp upward movement in the 1960s-70s (Billboard also used it). It came to mean rapidly rising or the best.
Verdict right

Why do mosquitoes exist, and should we kill them all?

Our guess
They're food for birds, bats and fish and part of the food chain; gene editing might reduce disease carriers.
Reveal the answer
The answer
Mosquito larvae feed fish and adults feed birds, bats and frogs, and males pollinate plants. Of about 3,500 species, only about 400 transmit diseases. Researchers are using CRISPR to make mosquitoes incapable of carrying disease or infertile instead of eradicating them.
Verdict right

Where do halftime shows come from?

Episode 143: Clown News · May 28, 2022 (00:00)
Our guess
College football marching bands, the ABA's gimmicks, circus performers or a Shakespeare-era intermission.
Reveal the answer
The answer
Many historians point to the Oorang Indians of the early NFL (1920s), whose owner Walter Lingo promoted his Airedale dog kennel with outrageous halftime shows. College football bands and cheerleaders also have a long history, and the ABA's Pacers had halftime events like Victor the Wrestling Bear.
Verdict right

Where does the phrase "get cold feet" come from?

Our guess
Dipping your toes in cold water and backing out, or the physiological response of anxiety drawing blood away from the extremities, from the late 1800s Old West.
Reveal the answer
The answer
Often attributed to Stephen Crane's 1896 Maggie: A Girl of the Streets, with earlier uses in Fritz Reuter's 1862 German novel (about a shoemaker) and possibly Ben Jonson's 1605 Volpone. The Italian "to be cold in the feet" meant to have no money, and the physiology of adrenaline is a plausible basis.
Verdict right

How many time zones does Russia have?

Our guess
About 10 or 11, spanning from Europe in the west to near Alaska in the east.
Reveal the answer
The answer
Eleven time zones, from Kaliningrad in the west to Kamchatka in the far east.
Verdict right

Where does the word "crapshoot" come from?

Episode 139: All the Good Things · April 30, 2022 (00:00)
Our guess
The dice game craps, probably in the lexicon since riverboat days and written down in the 1920s.
Reveal the answer
The answer
From the dice game craps (which may come from an Arabic game or Roman knucklebones). "Crapshoot" is a newer word: the earliest examples are from the 1960s and it wasn't widely used until the 1980s.
Verdict right

Where does the phrase "down the tubes" come from?

Episode 136: Literal Earworms · April 2, 2022 (01:11)
Our guess
An extension of "down the drain" or "down the crapper" from indoor plumbing, from around the 1950s.
Reveal the answer
The answer
It's a variant of "down the drain" (the British equivalent is "down the pan"). The earliest citation found is from a 1954 US sports report (the Charleston Daily Mail), and no clear mechanism is known.
Verdict right

Where does the phrase "put a pin in it" come from?

Episode 130: Candlestick Makers · February 19, 2022 (00:37)
Our guess
Tailoring (pinning fabric to sew later) or a push pin on a cork board, from the mid 1800s.
Reveal the answer
The answer
No firm origin. A tailoring origin seems plausible ("work cut out for you" dates to 1551), and an 1859 book uses "stick a pin in it" figuratively to mean setting something aside to return to later.
Verdict right

What is a nautical mile, and why is it different from a land mile?

Episode 129: Oblate Spheroid · February 12, 2022 (02:38)
Our guess
A unit based on latitude and longitude, about 15-20% longer than a land mile, used for navigation.
Reveal the answer
The answer
A nautical mile is one minute of latitude (about 1.15 statute miles). France tied it to the 1791 definition of the meter (one ten-millionth of a quarter meridian), and navigation by latitude and longitude took hold around 1500. A knot is one nautical mile per hour, originally measured by counting knots on a rope with a "common log". The statute mile goes back to the Roman 1,000 paces.
Verdict right

Can it be too cold to snow?

Episode 127: Bathtime Is So Much Fun! · January 22, 2022 (00:45)
Our guess
No, it needs moisture; very cold air holds less moisture, so snow is less likely, but it can't be too cold in principle.
Reveal the answer
The answer
It can be too warm to snow but not too cold. Snow can fall at very low temperatures given a moisture source, but heavy snowfall tends to occur when the air near the ground is relatively warm (about -9 C or warmer) because warmer air holds more water vapor. Very cold air is just too dry.
Verdict right

Where does the phrase "red herring" come from?

Episode 126: Throw Them Off the Scent · January 8, 2022 (02:09)
Our guess
A strong-smelling fish used to throw hunting dogs off the scent, or a way to swap in a cheaper fish in a market; 1800s detective novels.
Reveal the answer
The answer
Smoked and cured herring turns red and smells pungent. The figurative meaning appears in a 1686 gentleman's magazine, which suggested dragging a red herring across a fox's trail to confuse hounds, and a 1697 horsemanship tract suggested dragging a cat or fox carcass to train horses.
Verdict right

Where did Christmas trees come from, and what about hiding a pickle in the tree?

Episode 124: Big Little Gherkin · December 25, 2021 (01:10)
Our guess
A pagan winter evergreen tradition, adopted by Germans around the 1500s, with candles and pickle ornaments.
Reveal the answer
The answer
Germany is credited with the modern tradition in the 16th century, building on older pagan evergreen customs (the Romans had Saturnalia). A Martin Luther candle story is dubious, and German settlers brought it to America. The "Christmas pickle" tradition is probably an American invention by salesmen selling glass ornaments in the late 1800s.
Verdict right

Where does the phrase "chalk it up" come from?

Episode 123: Death and Gambling · December 11, 2021 (01:41)
Our guess
Scorekeeping, such as on chalkboards in darts, dog or horse racing, or at bars in the late 1800s.
Reveal the answer
The answer
From the custom of marking bar tabs and scores on a slate in pubs. It is attested in 1597 ("all my debts stand chalked up on the post for liquor"), and it came to mean to attribute something to a cause.
Verdict right

Where does the phrase "apple of my eye" come from?

Episode 122: Any Old Foreign Fruit · December 4, 2021 (01:00)
Our guess
The pupil is round like an apple, with the phrase going back to the Bible or Chaucer, around 1300.
Reveal the answer
The answer
It originally meant the pupil, the central aperture of the eye. It appears in Old English in 885 (King Alfred's translation of Gregory's Pastoral Care), in Shakespeare and in the 1611 King James Bible, which translated a Hebrew phrase meaning "little man of the eye". Apples themselves originated in Kazakhstan.
Verdict right

Where does the word "wheelhouse" (as in "in my wheelhouse") come from?

Episode 118: Remind Me to Fight You Later · November 6, 2021 (01:03)
Our guess
A water-wheel mill, a train turntable, or baseball's strike zone or boxing's reach.
Reveal the answer
The answer
Several sources: a ship's wheelhouse (the pilot house where the wheel is, or the housing around a paddlewheel), and baseball, where the batter's power zone is the "wheelhouse". Mark Twain used the term.
Verdict right

Where does the phrase "rule of thumb" come from?

Episode 116: Index of the Rest · October 23, 2021 (00:33)
Our guess
Falconry or a measuring technique using the thumb (sewing, estimating distance), from the Middle Ages.
Reveal the answer
The answer
The popular story that it comes from a legal limit on the thickness of a stick for beating a wife is a false etymology. The earliest print uses are 17th-century (a Scottish preacher, 1692), meaning a rough practical measure.
Verdict right

Why do we name hurricanes alphabetically, and when did that start?

Episode 115: Space Hangovers · October 16, 2021 (00:31)
Our guess
Late 1950s-early 1960s, with alphabetical female names, with male names added later.
Reveal the answer
The answer
In the early 1950s the National Hurricane Center used the phonetic alphabet (Able, Baker, Charlie), switched to alphabetical female names in 1953, and added male names in 1978-79. A storm is named once its winds reach 39 mph.
Verdict right

Why does a drop in barometric pressure signal a hurricane?

Episode 115: Space Hangovers · October 16, 2021 (04:24)
Our guess
A hurricane is a massive low-pressure system that sucks in warm air.
Reveal the answer
The answer
The eye of a hurricane is extremely low pressure, because warm air rises there, creating a cyclone. The lowest recorded pressure was Typhoon Tip at 870 millibars in 1979.
Verdict right

Do fish actually drink water?

Episode 113: Anatomy of a Facehole · October 2, 2021 (02:13)
Our guess
They take in water through their mouths and gills, with saltwater fish handling salt differently from freshwater fish.
Reveal the answer
The answer
Saltwater fish do drink water, directing some of it into the digestive tract to keep hydrated, while freshwater fish absorb water through their skin and gills by osmosis and do not need to drink.
Verdict right

How does color photography and color film work?

Episode 112: Messed Up, Man · September 25, 2021 (01:08)
Our guess
Film with three layers sensitive to different primary colors (red, green, blue) producing a color negative; digital pixels respond to one of three wavelengths. Mid-to-late 1930s.
Reveal the answer
The answer
The three-color method was suggested by James Clerk Maxwell in 1855 and Thomas Sutton produced the first color photograph in 1861. Kodachrome (1935) was the first modern three-layer color film. Digital sensors have pixels responsive to red, green or blue.
Verdict right

Where does the phrase "bang for your buck" come from, and why is a dollar a "buck"?

Episode 106: Bounce to the Ounce · August 14, 2021 (01:09)
Our guess
An American 20th-century phrase from advertising or the military, with "buck" from buckskins.
Reveal the answer
The answer
It was preceded by Pepsi's 1950 slogan "more bounce to the ounce" and was used by Defense Secretary Charles Wilson in 1954 for Eisenhower's "New Look" policy, with a 1940 ad as the earliest print citation. "Buck" for dollar goes back to deerskin trading (a 1748 reference), with a possible link to the "sawbuck" $10 bill.
Verdict right

Where does the word "beeline" come from?

Episode 105: Elementary Trigonometry · August 7, 2021 (00:36)
Our guess
A honeybee flying the most direct path back to the hive; one host suspected geometry (a bisecting line) or navigation.

Is the slur "cracker" from "cracker cows", and what is a cracker cow?

Episode 104: No Soul · July 31, 2021 (00:34)
Our guess
Not from the cow: probably from the crack of a whip (slave drivers or cattle herders), or from salty crackers.
Reveal the answer
The answer
Cracker cows are real (Florida cracker cattle, a small breed from Spanish stock). The word "cracker" for poor frontier whites likely comes from "whip cracker" (cattle drivers), and it existed even in Shakespeare's time as a word for a boaster. In the 1940s it became an epithet for bigoted whites.
Verdict right

How did American coins and paper money come about, and who is on them?

Episode 100: Eternal Knowledge · July 3, 2021 (25:58)
Our guess
A national currency in the early 1800s, coins early and paper money before the Civil War, with presidents added later.
Reveal the answer
The answer
The Mint Act of 1792 created the dollar and decimal coinage, with the first coins struck in 1793. The government didn't issue paper money until 1861 (only occasional treasury notes). Lincoln was the first historical figure on a coin (the 1909 penny), the Jefferson nickel is from 1938 and the FDR dime from 1946. A penny costs about 1.5 cents to make.
Verdict right

Is "heat lightning" a real thing?

Episode 98: Grill That Bird · June 19, 2021 (00:32)
Our guess
It's just regular lightning, perhaps cloud-to-cloud lightning with no thunder or storm directly overhead.
Reveal the answer
The answer
No. "Heat lightning" is ordinary lightning from a distant thunderstorm that is too far away for the thunder to be heard, and cloud-to-cloud lightning is common.
Verdict right

Why are there seven days in a week, and where do the day names come from?

Episode 97: Above Our Heads · June 12, 2021 (01:04)
Our guess
Roman planet and god names (Saturn, Sun, Moon), Norse gods for Thursday and Friday, and seven from the lunar cycle; Tuesday unknown.
Reveal the answer
The answer
The seven-day planetary week comes from the Babylonians and the Hellenistic Greeks, and the Romans replaced their eight-day cycle with it by about AD 60. Saturday, Sunday and Monday honor Saturn, the Sun and the Moon; Tuesday, Wednesday, Thursday and Friday honor the Germanic gods Tiw, Woden, Thor and Frigg/Freya. Tuesday's Tiw corresponds to the Roman god of war, Mars.
Verdict right

Where did all of Earth's water come from?

Episode 94: Impact Hypothesis · May 22, 2021 (01:16)
Our guess
Volcanic outgassing as the planet cooled, building an atmosphere, plus water brought by comets and meteors.
Reveal the answer
The answer
Not settled, but the leading idea is that much of it arrived from asteroids and comets (the deuterium-to-hydrogen ratio matches asteroids), possibly including the giant impact that formed the Moon. Outgassing from the early magma ocean contributed, and an atmosphere was needed to hold it.
Verdict right

Why did Reggie Miller wear number 31, and when did the Pacers retire it?

Episode 92: Stumpy · May 8, 2021 (00:06)
Our guess
13 reversed (the opposite of the unlucky number), and the Pacers retired it around 2005-06 after he retired.
Reveal the answer
The answer
He chose 31 because it's 13 reversed and because his sister Cheryl Miller wore it. The Pacers retired it in 2005 after his final season, he entered the Hall of Fame in 2012, and UCLA retired it in 2013 (it was already retired for Ed O'Bannon).
Verdict right

Why do flamingos stand on one leg?

Episode 89: Crop Milk · April 17, 2021 (00:33)
Our guess
To save energy and ease circulation for their long legs and small heart, and to avoid both feet getting stuck.
Reveal the answer
The answer
A locking joint lets them stand on one leg with no muscle effort, and tucking a leg also reduces heat loss through their legs and feet. A study found they stand on one leg more in colder water. They are pink from carotenoids in algae and brine shrimp.
Verdict right

Where does the phrase "straight from the horse's mouth" come from?

Episode 88: Long In the Tooth · April 10, 2021 (00:36)
Our guess
A courier or Pony Express rider, or checking a horse's teeth and mouth for its condition.
Reveal the answer
The answer
From examining a horse's teeth to judge its age and condition; the earliest print example found is from 1913 in horse racing, where the most trusted information came from the trainers. A related phrase, "don't look a gift horse in the mouth", goes back to St. Jerome around AD 400.
Verdict right

Where does the phrase "bought the farm" come from?

Episode 85: Bulging Vessel · March 20, 2021 (01:08)
Our guess
Soldiers who planned to buy a farm after the war, or a dead person's farm being sold, or an insurance payout letting family pay off the farm.
Reveal the answer
The answer
The most accepted etymology is that wartime pilots dreamed of buying a farm after the war, and when one was killed, the insurance payout or military pension allowed his family to pay it off.
Verdict right

How do countries get paid when international mail crosses several postal services?

Episode 81: Address Was Directions · February 20, 2021 (00:37)
Our guess
Originally goodwill between postal services, later contracts where each country's postage includes a fee for the receiving country's post or a private carrier.
Reveal the answer
The answer
Your postage covers domestic handling, transport (often via a private carrier like FedEx or UPS), and a fee paid to the receiving country's postal service. The Universal Postal Union, founded in 1874 and based in Switzerland, sets the fees, and before that mail depended on bilateral treaties.
Verdict right

How does praying mantis reproduction work given that the female may eat the male?

Episode 80: Snack Sized · February 13, 2021 (00:37)
Our guess
Large clutches of eggs, possibly skewed toward males, with cannibalism not happening every time.
Reveal the answer
The answer
Cannibalism occurs in about 25% of encounters and is mostly seen in captivity, driven largely by hunger. Cannibalistic females laid more eggs (about 88 vs. 37 in one study). An egg case hatches 100-200 mantises, of which only about a third reach maturity.
Verdict right

Why is it called the Super Bowl, and why are football games called bowls?

Episode 79: Whole Bowl of Cherries · February 6, 2021 (01:04)
Our guess
Because stadiums are shaped like bowls, or because of a trophy; and the Super Bowl name came from a toy.
Reveal the answer
The answer
"Bowl" comes from the Rose Bowl, the first post-season college football game, and the Yale Bowl's bowl-shaped stadium design. "Super Bowl" came from Lamar Hunt, whose daughter played with a toy called the Super Ball.
Verdict right

Why does Santa Claus have elves?

Episode 72: Pre-Tolkien · December 19, 2020 (01:04)
Our guess
A holdover from Nordic or druid pagan myth, added in the 1800s to explain who makes the toys.
Reveal the answer
The answer
Elves come from ancient Scandinavian and Celtic folklore as nature spirits that guarded homes. The 1823 poem "A Visit from St. Nicholas" calls Santa a "jolly old elf", an 1857 Harper's Weekly poem has him keeping elves at work, and by 1891 he merged with the Swedish "tomte".
Verdict right

What is the difference between polenta and grits?

Episode 69: Polenta in the Morning · November 28, 2020 (00:34)
Our guess
Both are cornmeal, differing by how they are cooked, the time of day, or the region.
Reveal the answer
The answer
Both are cornmeal. Polenta is coarser ground yellow corn from Italian cuisine, while grits is a finer grind of white corn (hominy) and is a Southern American dish.
Verdict right

Where do coyotes and hyenas come from if dogs come from wolves?

Episode 67: Dogma · November 14, 2020 (00:31)
Our guess
They're not descended from wolves or dogs; coyotes, wolves and perhaps hyenas share a common ancestor.
Reveal the answer
The answer
The gray wolf and coyote are close relatives from a common ancestor and were not bred by humans. Hyenas are not canids at all; they are their own family and are more closely related to cats than to dogs.
Verdict right

Where does the term "sugar daddy" come from?

Episode 66: All About the Spreckels · November 7, 2020 (00:33)
Our guess
A 20th century double entendre, with sugar standing for sweetness or money, possibly from pimping.
Reveal the answer
The answer
The most widespread story involves sugar magnate Adolph Spreckels and his wife Alma, 24 years his junior, around 1908. The earliest recorded use is 1923, when "sugar" was slang for money, and a candy called Papa Sucker renamed itself "Sugar Daddy".
Verdict right

What is the history of the jack-o'-lantern, and why do we carve pumpkins?

Episode 65: Where Are the Bodies?! · October 31, 2020 (01:37)
Our guess
A Celtic Halloween tradition carried to America by immigrants, with pumpkins an easy surplus gourd.
Reveal the answer
The answer
It comes from the Irish legend of Stingy Jack, who was doomed to roam with a coal in a hollowed turnip, and from the will-o'-the-wisp lights over peat bogs. The custom of carving them for Halloween began in Ireland in the 19th century, and immigrants switched to pumpkins in America.
Verdict right

Is a slug just a snail without a shell?

Episode 62: Snail with a Housing Problem · October 10, 2020 (00:32)
Our guess
They are closely related but distinct species, because snails grow their own shell and slugs never do.
Reveal the answer
The answer
Both are gastropods in the phylum Mollusca, and slugs often have a small internal or vestigial shell. They are closely related but separate species, and land snails and slugs are the only gastropods living on land. Snails live 2 to 3 years in the wild and up to 15 in captivity.
Verdict right

Where does the phrase "if I had my druthers" come from?

Episode 61: Drunk Others · October 3, 2020 (01:06)
Our guess
A folksy Southern contraction of "I'd rather", perhaps from Mark Twain.
Reveal the answer
The answer
"Druthers" is a late-19th-century American contraction of "would rather" ("I'd rather" to "druther"). One of the first known uses in print is by Mark Twain in Tom Sawyer.
Verdict right

Where does the word "okay" come from?

Episode 58: Small Potatoes · September 12, 2020 (00:31)
Our guess
From "Old Kinderhook", a political nickname from the 1840s, shortened to O.K.
Reveal the answer
The answer
It became nationally popular in the 1840 election as a slogan for "Old Kinderhook", Martin Van Buren's nickname (he was from Kinderhook, New York). It began as a joking abbreviation of "all correct" in an 1839 Boston newspaper, during a fad for abbreviations. Other etymologies are debated.
Verdict right

Where do "cooties" and the "cootie shot" come from?

Episode 57: Copulation of Tortoises · September 5, 2020 (00:30)
Our guess
An American schoolyard game from the early 1900s, with the word possibly tied to "cuties", "cooter" or a wartime disease, and the shot modeled on vaccines like polio.
Reveal the answer
The answer
"Cooties" is thought to come from Malay/Austronesian "kutu" (a biting parasite). British soldiers used it for lice in the trenches of World War I, and usage spiked around 1920. By the mid-20th century North American kids used it for an imaginary germ, and the "shot" likely echoes polio vaccination.
Verdict right

Why are they called "bread and butter pickles"?

Episode 54: #Blessed · August 15, 2020 (00:32)
Our guess
A basic, everyday staple pickle (your "bread and butter"), probably a cheap, sweeter Depression-era sandwich pickle.
Reveal the answer
The answer
The name comes from Omar and Cora Fanning, Illinois cucumber farmers who sold sweet and sour pickles in the 1920s and trademarked "Fanning's Bread and Butter Pickle" in 1923. They were a cheap staple during the Depression.
Verdict right

Where does the phrase "down to the wire" come from?

Episode 53: Bombs For Good · August 8, 2020 (00:34)
Our guess
Horse racing, with a wire marking the finish line to help judges (an earlier guess was MacGyver-style bomb wires).
Reveal the answer
The answer
From late 1800s horse racing, when a wire was strung across the track above the finish line to help judges determine which horse crossed first. A wire was also used at the start line, and "wire to wire" means leading from start to finish.
Verdict right

Why do we have lawns?

Episode 51: I've Got a Goat Guy · July 25, 2020 (01:02)
Our guess
A status symbol of wealth starting with castles and aristocrats and then imitated in suburbia, and perhaps keeping a clear line of sight.
Reveal the answer
The answer
The hosts' guess matched the research: lawns began around castles, where sheep and goats kept them grazed, and were later copied by landowners. The lawnmower and designers like Frederick Law Olmsted spread them. One theory is that humans prefer short grass because savannas helped them spot danger.
Verdict right

Where does the phrase "handle with kid gloves" come from?

Episode 45: Mittens Romney · June 13, 2020 (00:30)
Our guess
Gloves made from baby goat leather, soft and fancy, perhaps from 15th-16th century English nobility.
Reveal the answer
The answer
Kid gloves are made from the skin of young goats, which is very soft. Mentions go back to 1730s England, where the term was a slight implying daintiness. The figurative use appeared in America, with early print examples in an 1849 magazine and Alice's Adventures in Wonderland (1865).

Verdict right

Where does the word "picnic" come from?

Our guess
French, and more recent than medieval; one host guessed the early 1800s, another Hungarian.
Reveal the answer
The answer

Verdict right

What is the history of Valentine's Day?

Episode 28: The Angel Sniper · February 15, 2020 (01:40)
Our guess
A pagan holiday that the Catholic Church cleaned up by attaching a saint; Cupid is Roman rather than Greek.
Reveal the answer
The answer
It traces to the Roman feast of Lupercalia (February 13-15). Two men named Valentine were executed on February 14 in the third century, and Pope Gelasius I later merged the saint's day with Lupercalia. Chaucer and Shakespeare romanticized it, and Hallmark began making Valentine's cards in 1913. Cupid is Roman, the son of Venus and Mars; his Greek counterpart is Eros.
Verdict right

Where does Groundhog Day come from?

Episode 26: Day of the Marmot · February 1, 2020 (05:49)

Verdict right

Where does the phrase "in one fell swoop" come from?

Episode 23: Dr. Guillotine · January 11, 2020 (00:33)
Our guess
Falconry, though some argued "fell" implied felling a tree or a beheading.
Reveal the answer

"Fell" is old English for cruel or terrible, and "swoop" is the sudden attack of a bird of prey. It appears in Shakespeare's Macbeth, when Macduff learns his family was killed "at one fell swoop".
Verdict right

Why do rabbits have little cotton-ball tails?

Episode 22: Too Cute To Kill · January 4, 2020 (00:30)
Our guess
Not balance; more likely self-defense, such as confusing predators with the white flash or masking scent, or a vestigial leftover.
Reveal the answer
The answer
A biologist's theory is that the white tail confuses predators during the chase: it disappears when the rabbit turns, forcing the predator to refocus. The research is not peer reviewed. Deer may also flick their tails to signal danger.
Verdict right

Why do people kiss under mistletoe, and where does the word come from?

Episode 20: Slutty Peasants · December 21, 2019 (01:42)
Our guess
A northern European, probably English or Celtic, custom taken from pagans and attributed to peasants; not Germanic.
Reveal the answer
The answer
The kissing custom is English, where a berry was picked before each kiss. The romantic overtones are linked to Druids, the Greek festival of Saturnalia, and a Norse myth in which Loki killed Baldur with a mistletoe arrow. The word comes from German "mistel" (dung) and "tan" (twig), because the plant spreads through bird droppings.
Verdict right

What is the history and meaning of the middle finger, and why is it called "the bird"?

Episode 14: Give the Big Bird · November 9, 2019 (00:32)
Our guess
A clear signal at a distance, probably phallic or sexual in origin.
Reveal the answer
The answer
In ancient Greece and Rome it represented the phallus (the Greeks called it "catapygon"), with the neighboring fingers standing for the testicles. In the US it dates to the 1890s, possibly via Italian immigrants. "The bird" comes from the 1860s expression "give the big bird", meaning to hiss like a goose.
Verdict right

What is the history behind Halloween?

Episode 12: Soul Cakes · October 26, 2019 (00:36)
Our guess
A pre-Christian pagan harvest festival tied to the end of the growing season, which Christians took over with All Saints' Day around the Middle Ages.
Reveal the answer
The answer
It traces to the Celtic festival of Samhain (the new year on November 1, when the dead were thought to return). The Christian feast of All Hallows was set around 731-741 under Pope Gregory III, and Halloween is roughly 2,000 years old. Pumpkin pie is much more recent, with recipes from the 1670s.

What is the difference between a llama and an alpaca?

Episode 6: Like a Chorizo · September 14, 2019 (00:00)
Our guess
Closely related but different animals; alpacas live at higher altitude and are used for fur, llamas are pack animals.
Reveal the answer
The answer
Both are domesticated South American camelids. Llamas are bigger (up to about 400 lb) and bred as pack animals; alpacas are smaller (100-175 lb) and bred for fiber for about 6,000 years. Llamas have long banana-shaped ears, alpacas shorter spear-shaped ones. They can crossbreed, producing a huarizo.
