A chicken once lived for 18 months without its head. That’s not a metaphor. That’s a rooster named Mike from Fruita, Colorado, who toured the country as a sideshow attraction in the 1940s, fed through an eyedropper directly into his exposed esophagus. His owner made the equivalent of $50,000 a month showing him off. I’ve opened trivia nights with that fact and watched an entire room of adults silently recalibrate what they thought was possible in this world.
The people who search for weird trivia already know the world is strange. They’ve read the Wikipedia rabbit holes. They’ve texted friends screenshots of things that shouldn’t be true. What they want isn’t just oddity. They want the specific, verifiable kind of weirdness that makes someone across the table put down their drink and say no way. That’s what these fifty questions are built to do.
The Ones That Sound Made Up
1. What was the name of the famous headless chicken who survived for 18 months after a botched decapitation in 1945?
I just told you this one. Consider it a gift. If you weren’t paying attention, that’s on you.
Show Answer
Mike the Headless Chicken. The axe missed his jugular vein and left most of his brainstem intact, which is why he could still walk, perch, and attempt to crow. Most common wrong answer: people guess “Lucky,” which is both too obvious and too ironic.
2. In what country is it illegal to own just one guinea pig, because it’s considered animal cruelty due to loneliness?
This question splits rooms perfectly. Half the people think it’s a joke. The other half start arguing about which Scandinavian country it must be.
Show Answer
Switzerland. They have some of the most detailed animal welfare laws in the world, including regulations about the social needs of specific species. There’s even a guinea pig rental service for when one of a pair dies.
3. Oxford University in England is older than what major civilization’s empire?
This is the kind of weird trivia that makes people angry. They don’t want it to be true. It rewires something in how they think about time.
Show Answer
The Aztec Empire. Oxford has records of teaching dating back to 1096. The Aztec Empire wasn’t founded until 1428. Most people guess something like the Roman Empire, which makes the question feel impossible. But the Aztecs were surprisingly recent.
4. What common fruit shares approximately 60% of its DNA with humans?
Show Answer
Bananas. This fact gets thrown around a lot, but it still lands every time because people can never quite remember the percentage or the fruit. Some people confidently say “tomato,” which is close at about 60% too, but banana is the famous answer.
5. In 1932, Australia fought and lost a military campaign against what animal?
I’ve watched Australian players physically wince at this one. They know exactly what’s coming.
Show Answer
Emus. The Great Emu War involved soldiers with Lewis guns trying to cull a population of roughly 20,000 emus devastating farmland in Western Australia. The emus won. The military withdrew after using 2,500 rounds per confirmed kill.
6. What lake in Cameroon killed nearly 1,800 people in 1986 without any volcanic eruption, earthquake, or flood?
This is a question that changes the temperature of a room. People stop joking around.
Show Answer
Lake Nyos. A massive release of carbon dioxide from beneath the lake formed an invisible cloud that suffocated nearly every living thing within 16 miles. Scientists call it a limnic eruption. It killed people in their sleep.
7. What color does Coca-Cola turn if you remove the caramel coloring?
Show Answer
Green. Or more precisely, a murky greenish-yellow. This surprises almost everyone, though some people confidently say “clear,” imagining it works like water with food coloring dropped in. The actual chemical composition gives it that color naturally.
Bodies Are Stranger Than You Think
8. How many times does the average human heart beat in a single day?
Give or take 10,000 and I’ll accept it. The point isn’t precision. The point is that the number is absurd.
Show Answer
Approximately 100,000 times. People consistently guess too low. Something about hearing “100,000” makes them realize they’ve never actually thought about what their heart does all day.
9. What organ in the human body can regenerate itself even after up to 75% of it has been removed?
Show Answer
The liver. It’s the only internal organ that can do this, which is why living-donor liver transplants are possible. The donated portion regrows to nearly full size in both the donor and the recipient within weeks.
10. Humans share a bathroom habit with what other animal, making them two of the only species known to enjoy spicy food?
The phrasing throws people. They’re so focused on “bathroom habit” that they forget to think about the spicy food part.
Show Answer
Tree shrews. Research published in PLOS Biology found that tree shrews actively seek out capsaicin-rich peppers. Most mammals avoid capsaicin. Humans and tree shrews are the weird ones here.
11. What part of your body has no blood supply and gets its oxygen directly from the air?
Show Answer
The cornea of your eye. It’s one of the only tissues in the human body that’s completely avascular. This is also why contact lens technology has to account for oxygen permeability.
12. How long is the total length of blood vessels in an average adult human body: 60,000 miles, 100,000 miles, or 250,000 miles?
Show Answer
Approximately 100,000 miles. That’s enough to wrap around the Earth about four times. People who pick 60,000 are being conservative. People who pick 250,000 are being hopeful. The real number sits right in the middle and still feels impossible.
13. Stomach acid is strong enough to dissolve what common metal?
I love this question because everyone has a stomach and nobody respects it enough.
Show Answer
Zinc. Hydrochloric acid in the stomach has a pH between 1 and 3, strong enough to dissolve small zinc objects. The stomach lining replaces itself every few days specifically because the acid would destroy it otherwise.
History Got Weird Before the Internet
14. During the Victorian era, what toxic substance was commonly used as a green dye in wallpaper, dresses, and even children’s toys?
Show Answer
Arsenic. Specifically, a pigment called Scheele’s Green and later Paris Green. It’s been theorized that Napoleon’s death was hastened by arsenic-laced green wallpaper in his room on Saint Helena, though that’s still debated.
15. What did ancient Romans use as mouthwash?
Every table groans at this one. They already suspect the answer. They just don’t want to be right.
Show Answer
Urine. Specifically, imported Portuguese urine was considered premium quality. The ammonia in it actually does have cleaning properties, and it was used for laundry too. Emperor Vespasian even taxed the urine trade.
16. In medieval Europe, animals could be put on trial for crimes. What animal was most commonly tried in court?
Show Answer
Pigs. They were the most frequent defendants, usually for attacking or killing children. The trials included appointed defense lawyers, witnesses, and formal sentencing. Some pigs were even dressed in human clothes for their court appearances.
17. What common war tactic did Genghis Khan’s army use that involved lighting animals on fire?
Show Answer
They tied burning materials to the tails of cats and birds, then released them toward enemy fortifications. The panicked animals would flee into buildings and set them ablaze. Multiple historical armies used variations of this, but the Mongols are the most cited.
18. In 1518, a “dancing plague” struck what European city, where hundreds of people danced uncontrollably for days, some until they collapsed and died?
Show Answer
Strasbourg (then part of the Holy Roman Empire, now in France). It started with one woman dancing in the street in July and spread to around 400 people over the course of a month. Authorities initially prescribed more dancing as the cure. It didn’t help.
19. What did ancient Egyptians use as a contraceptive that involved crocodile dung?
Show Answer
They mixed crocodile dung with honey and sodium carbonate to form a pessary (a vaginal suppository). The alkaline properties of the dung may have actually had some spermicidal effect, though I wouldn’t recommend testing that theory.
20. During World War II, the British military seriously considered a plan to build an aircraft carrier out of what material?
This one gets the engineers in the room excited. Everyone else thinks you’re lying.
Show Answer
Ice. Project Habakkuk proposed building a massive aircraft carrier from pykrete, a frozen mixture of water and wood pulp that’s remarkably strong and slow to melt. A prototype was built on a lake in Canada. The war ended before the full-scale version could be attempted.
Nature Doesn’t Care About Your Comfort
21. What animal can survive being frozen solid and then thaw back to life?
Show Answer
The wood frog. During winter, up to 65% of the water in its body freezes. Its heart stops. Its brain shows no activity. Then spring comes, it thaws out, and hops away. They produce a kind of natural antifreeze that protects their cells from ice crystal damage.
22. A group of flamingos is called what?
People always guess “flock.” Technically correct but boring. The proper collective noun is better.
Show Answer
A flamboyance. Yes, really. And it’s one of the few collective nouns that feels like it was named by someone who actually watched the animals.
23. What sea creature has three hearts, blue blood, and a donut-shaped brain?
Show Answer
The octopus. Two hearts pump blood to the gills, one pumps it to the rest of the body. Their blood is blue because it uses copper-based hemocyanin instead of iron-based hemoglobin. And their esophagus passes through their brain, so if they eat something too large, it can cause brain damage.
24. What percentage of the Earth’s species are estimated to still be undiscovered: 20%, 50%, or 80%?
Show Answer
Approximately 80%. Scientists estimate there are around 8.7 million eukaryotic species on Earth, and we’ve only cataloged about 1.5 million. The deep ocean alone could contain millions of unknown species. This number always makes people quiet for a second.
25. What animal sleeps with one eye open because half its brain stays awake?
Multiple correct answers here, but there’s a most famous one.
Show Answer
Dolphins. It’s called unihemispheric sleep. One half of the brain rests while the other stays alert for predators and controls breathing. Some birds do it too, particularly when sleeping at the edge of a flock.
26. The tongue of a blue whale weighs approximately as much as what large animal?
Show Answer
An elephant. A blue whale’s tongue can weigh around 5,400 pounds, roughly the weight of a young African elephant. Their heart alone is the size of a golf cart. Blue whales break every intuition you have about size.
27. What insect can survive for up to a week without its head?
Show Answer
A cockroach. They breathe through spiracles in their body segments, not through their mouth. They eventually die of dehydration because they can’t drink water. The head, meanwhile, can survive for several hours on its own, waving its antennae.
28. What is the only mammal that can truly fly?
This question catches more people than you’d think. Everyone knows the answer. Not everyone trusts that they do.
Show Answer
Bats. Flying squirrels glide. Sugar gliders glide. Colugos glide. Only bats achieve true powered flight. People sometimes second-guess themselves because it feels too obvious, which is exactly why I include it.
The Human Race Is the Weirdest Part
29. In Japan, there’s a word for buying more books than you can ever read. What is it?
I’ve never asked this question without at least three people nodding in guilty recognition.
Show Answer
Tsundoku. It combines “tsunde” (to pile up) with “oku” (to leave for a while). It’s not considered a disorder. It’s just a thing that happens. The Japanese language has a lot of words like this for experiences that English forces you to describe in a full sentence.
30. What phobia is the fear of long words?
The answer to this one is either cruel or hilarious depending on your perspective.
Show Answer
Hippopotomonstrosesquippedaliophobia. Yes. The word for the fear of long words is 36 letters long. Someone at some point made a deliberate choice, and I respect the commitment.
31. In what U.S. state is it technically illegal to carry an ice cream cone in your back pocket?
Show Answer
Alabama (and Georgia, and a few others have variations). The law dates back to when horse theft was common. People would lure horses away by putting an ice cream cone in their back pocket, so the horse would follow them. The law targeted the method, not the dessert.
32. What is the most stolen food in the world?
Show Answer
Cheese. According to a global retail crime survey, about 4% of all cheese produced worldwide ends up stolen. There’s even a black market for high-end cheeses. The phrase “cheese heist” has appeared in actual police reports.
33. In 2008, the country of Liechtenstein accidentally invaded what neighboring country?
The word “accidentally” does a lot of work in this question. People hear it and can’t decide if they should laugh or be concerned.
Show Answer
Switzerland. A unit of 170 Liechtenstein soldiers on a training exercise marched about a mile into Swiss territory before realizing their mistake. Switzerland didn’t notice. Both countries described the incident as “not a big deal.”
34. What is the official national animal of Scotland?
Show Answer
The unicorn. Scotland has used the unicorn as a heraldic symbol since the 12th century. In Celtic mythology, the unicorn represented purity and power. It’s depicted in chains on the Royal Coat of Arms, symbolizing the dangerous power of an untamed unicorn. People always think you’re joking.
35. How many years did the shortest war in recorded history last?
Trick phrasing. It didn’t last years.
Show Answer
The Anglo-Zanzibar War of 1896 lasted between 38 and 45 minutes, depending on the source. The British Empire issued an ultimatum. Zanzibar didn’t comply. The Royal Navy opened fire. It was over before lunch. People who guess “one day” are off by about 23 hours.
36. Cleopatra lived closer in time to the moon landing or to the construction of the Great Pyramid of Giza?
This is the weird trivia question that broke the internet a decade ago. It still breaks rooms today.
Show Answer
The moon landing. Cleopatra lived around 30 BC. The Great Pyramid was built around 2560 BC. That’s a gap of about 2,500 years. The moon landing was only about 2,000 years after Cleopatra. The pyramids were already ancient to her.
Food Gets Weird Fast
37. What popular candy was originally invented as a way to help people quit smoking?
Show Answer
PEZ. The name comes from the German word for peppermint, “Pfefferminz.” It was marketed as a breath mint and smoking alternative in 1927. The kid-friendly dispensers didn’t come until the 1950s, when they pivoted hard toward the children’s market.
38. What is the most expensive spice in the world by weight?
Show Answer
Saffron. It can cost $5,000 or more per pound because each crocus flower produces only three tiny stigmas, and they must be harvested by hand. It takes about 75,000 flowers to produce a single pound of saffron. People sometimes guess vanilla, which is the second most expensive.
39. Honey never spoils. Edible honey has been found in tombs in what ancient civilization?
Show Answer
Ancient Egypt. Archaeologists have found 3,000-year-old honey in Egyptian tombs that was still perfectly edible. Honey’s low moisture content, acidity, and natural hydrogen peroxide production make it essentially immortal.
40. What fast food chain’s ice cream machines are so frequently broken that the FTC launched an investigation into why?
This question gets a laugh before anyone even answers. Everyone already knows.
Show Answer
McDonald’s. The FTC investigated in 2021 after years of complaints. The machines require a complex four-hour pasteurization cycle and frequently display error codes that only authorized technicians can diagnose. A startup called iCEE actually created a device to help franchisees fix the machines themselves, and the manufacturer threatened legal action.
41. What fruit was once so expensive in England that people would rent them for the evening to display at dinner parties?
Show Answer
Pineapples. In 17th and 18th century England, a single pineapple could cost the equivalent of $8,000 today. People rented them as centerpieces. There were even pineapple-shaped buildings constructed as status symbols. This is why pineapples became a symbol of hospitality.
Space Is Just Weird on a Bigger Scale
42. What does space smell like, according to astronauts who’ve been on spacewalks?
This question always gets a moment of pure silence. People are processing the fact that space has a smell.
Show Answer
Seared steak, gunpowder, and raspberries. Multiple astronauts have described the lingering scent on their suits after EVAs. The smell is attributed to polycyclic aromatic hydrocarbons, which are dying stars’ chemical byproducts. NASA even hired a fragrance chemist to recreate the scent for training purposes.
43. A day on Venus is longer than a year on Venus. True or false?
Show Answer
True. Venus takes about 243 Earth days to rotate once on its axis, but only about 225 Earth days to orbit the Sun. So a single Venusian day is longer than a Venusian year. It also rotates backwards compared to most planets, so the Sun rises in the west.
44. What planet in our solar system rains diamonds?
Show Answer
Both Neptune and Saturn are believed to rain diamonds. Extreme pressure and temperature deep in their atmospheres compress carbon into diamond crystals that fall like hailstones. Scientists recreated this process in a lab in 2017. Accept either planet.
45. How many times has Earth’s magnetic north and south pole completely flipped in the last 20 million years?
Show Answer
Roughly 100 times. Geomagnetic reversals happen irregularly, averaging about every 200,000 to 300,000 years. The last one was about 780,000 years ago, which means we’re statistically overdue. During a reversal, compasses would point south. The process takes a few thousand years, not overnight.
The Ones That Start Arguments
46. What percentage of the ocean floor has been mapped in detail as of 2024: about 5%, 25%, or 50%?
Show Answer
About 25% (as of recent estimates, up from about 5% just a decade ago thanks to the Seabed 2030 project). We have better maps of Mars than we do of our own ocean floor. This fact consistently makes people uncomfortable.
47. There are more possible iterations of a game of chess than there are atoms in the observable universe. What is this number commonly called?
Show Answer
The Shannon number, named after mathematician Claude Shannon, who estimated it at roughly 10^120. The number of atoms in the observable universe is estimated at about 10^80. Chess players nod knowingly at this. Everyone else stares into the middle distance.
48. What everyday object was originally invented in 1839 but wasn’t successfully marketed for another 20 years because nobody could figure out what it was for?
I love questions where the answer reframes something you use without thinking.
Show Answer
The rubber band. Charles Goodyear vulcanized rubber in 1839, but rubber bands weren’t patented until 1845 by Stephen Perry, and they didn’t find widespread commercial use until the 1860s. People just couldn’t figure out what to do with stretchy loops of rubber. Now they’re everywhere and we can’t imagine life without them.
49. What is the technical term for the phenomenon where you walk into a room and forget why you went there?
Everyone in the room suddenly feels seen when I ask this one.
Show Answer
The “doorway effect,” studied formally by researcher Gabriel Radvansky at the University of Notre Dame. His experiments showed that passing through a doorway serves as an “event boundary” in the mind, causing the brain to file away the previous room’s thoughts and start fresh. It’s not aging. It’s architecture.
50. There’s a town in Norway called Hell. What happens there every winter that makes its name accidentally perfect?
I’ve closed more trivia nights with this question than any other. Not because it’s the hardest. Because it’s the one that leaves people smiling and shaking their heads at the same time. The world is weirder than we give it credit for. The best weird trivia doesn’t just surprise you. It makes you wonder what else you’ve been walking past without noticing.
Show Answer
It freezes over. Hell, Norway regularly drops below freezing in winter, meaning “Hell freezes over” is a literal, annual meteorological event. The town leans into it. They sell postcards. The train station sign is one of the most photographed in Scandinavia. Sometimes the weirdest things are just the truest ones.
I've hosted pub quiz nights in New York, NY for 11 years, which means I've written somewhere north of ten thousand questions and watched real rooms react to all of them. I know what makes people lean in, what makes them groan, and what makes them come back next week. My question packs have featured on Buzzfeed Quizzes, and I take the same care with every set I write.
