50 Common Misconceptions (Ep.1)

Hi, I’m John Green, and welcome to a fun journey through some common misconceptions! Let’s dive into some surprising facts that might just blow your mind.

Did you know that Vikings never wore helmets with horns? This idea only came about in 1876 during a performance of Wagner’s opera “The Ring of the Nibelung.”

The Truth About Iron Maidens

Iron maidens, those scary medieval torture devices, are actually fictional. They never existed in real life!

Marie Antoinette’s Famous Quote

Marie Antoinette never said “Let them eat cake” when she heard about starving peasants. It’s just a myth!

Anne Boleyn’s Fingers

Anne Boleyn, a famous French royal, did not have eleven fingers. Most historians agree this is just a rumor.

Signing the Declaration of Independence

The American Declaration of Independence wasn’t signed on July 4, 1776. It was actually signed on August 2, 1776.

The U.S. Constitution’s Paper

The U.S. Constitution wasn’t written on hemp paper. It was written on parchment.

Napoleon’s Height

Napoleon wasn’t short for his time. He was about five feet seven inches tall, which was slightly above average back then.

Einstein and Math

Albert Einstein didn’t fail math in school. In fact, he mastered complex math like calculus before he was fifteen!

JFK’s Famous Speech

When John F. Kennedy said “Ich bin Ein Berliner,” he didn’t call himself a jelly doughnut. People in Berlin understood what he meant.

The Meaning of Sushi

Sushi doesn’t mean raw fish. It actually means “sour rice.”

Microwaving Metal

Putting metal in a microwave is a bad idea, but it doesn’t ruin the microwave. Just don’t try it at home!

The Origin of “Crap”

The word “crap” doesn’t come from Thomas Crapper, who helped develop indoor plumbing. It actually comes from Latin.

Police Code 420

The number 420 isn’t a police code for marijuana possession. It actually means juvenile disturbance.

The Great Wall of China from Space

The Great Wall of China isn’t the only man-made object visible from space. In fact, it’s not visible from space at all!

Elephant Graveyards

There’s no such thing as an elephant graveyard. Elephants don’t go to a special place to die.

Sharks and Cancer

Despite what some people think, sharks can get cancer, and using shark cartilage doesn’t cure cancer.

Chameleons and Color Change

Chameleons don’t change color just to blend in. They do it to regulate their temperature and communicate.

Throwing Rice at Weddings

Throwing rice at weddings doesn’t cause birds to explode. This has never happened!

Earthworms and Regeneration

Cutting an earthworm in half doesn’t create two worms. Usually, both halves die, or only one survives.

More Than Five Senses

Humans have more than five senses. We can sense time, acceleration, and even the position of our limbs.

Shaving Myths

Shaving doesn’t make hair grow back thicker or coarser. That’s just a myth.

Fingernails After Death

Your fingernails don’t keep growing after you die. It’s just an illusion.

Swallowing Gum

If you swallow gum, it won’t stay in your stomach for seven years. It passes through like everything else you eat.

Brain Usage

We use more than 10% of our brains. The idea that we don’t is just a misunderstanding.

Warts and Toads

You can’t catch warts from toads. Warts come from viruses, not toads.

Pennies from the Empire State Building

A penny dropped from the Empire State Building won’t kill someone. It doesn’t fall fast enough to be deadly.

Abner Doubleday didn’t invent baseball, and he never claimed to.

Caesar Salad’s Origin

Caesar salad wasn’t named after Julius Caesar. It was created by Caesar Cardini in Tijuana, Mexico, in 1924.

Famous Misquotes

Ron Burgundy’s Quote

Ron Burgundy never said, “Well, that escalated quickly.” He actually said, “Boy, that escalated quickly.”

Human Evolution

Humans didn’t evolve from chimps. We share a common ancestor but evolved separately.

Chest of Drawers

It’s called a “chest of drawers,” not “chester drawers.”

Don Juan’s Pronunciation

In Byron’s poem, Don Juan is pronounced to rhyme with “ruin.”

You wouldn’t explode in the vacuum of space. It’s a misconception from movies.

No one was burned at the stake during the Salem Witch Trials. People were hanged or crushed, but not burned.

Blondes and redheads aren’t going extinct. That’s just a myth.

Hi, I’m John Green, and this is mental_floss.

1. Vikings never wore horns on their helmets—at least not until an 1876 staging of Wagner’s opera “The Ring of the Nibelung.”

2. You know iron maidens? The medieval torture device that inspired a famous heavy metal band? Yeah, they were fictional.

3. Marie Antoinette never said “Let them eat cake” when told peasants were starving due to lack of bread.

4. And while we’re on the topic of French royal women who lost their heads, Anne Boleyn did not have eleven fingers, or at least most historians don’t think so.

5. The American Declaration of Independence was not signed on July 4, 1776. It was signed on August 2, 1776.

6. Also, the U.S. Constitution was not written on hemp paper but on parchment.

7. Napoleon did not have a Napoleon Complex, as he was five feet seven inches tall, slightly above average height for his time.

8. Albert Einstein didn’t fail math in school, and when he was shown a newspaper column claiming he had, Einstein responded, “Before I was fifteen, I had mastered differential and integral calculus.”

9. John F. Kennedy did not say, “I am a jelly doughnut” when he said “Ich bin Ein Berliner.” No one in Berlin was confused on that day about what Kennedy was saying.

10. Sushi does not mean raw fish; it means “sour rice.”

11. Placing metal in a microwave doesn’t ruin the microwave. I mean, it’s definitely a bad idea, but look, we just microwaved this tin foil and now in the smoldering remains, I am microwaving a hot pocket.

12. The word “crap” is not derived from Thomas Crapper, who helped give us indoor plumbing. Sadly, “crap” just comes from Latin, like many other words.

13. 420 is not the Los Angeles police code for marijuana possession. Police Code 420 just means juvenile disturbance, which only sometimes involves marijuana possession.

14. The Great Wall of China is not the only man-made object visible from space. Many man-made objects are visible from space, and the Great Wall is not among them.

15. There’s no such thing as an elephant graveyard where old elephants go to die. When elephants are ready to die, they just do it, like the rest of us.

16. The 1992 book “Sharks Don’t Get Cancer” led to an increase in people using ground-up shark cartilage to treat cancer, but that doesn’t work, and sharks do get cancer.

17. Chameleons don’t primarily change color to camouflage. It helps them regulate their temperature and is a way of communicating.

18. Throwing rice at weddings does not lead to birds eating that rice and then the rice expanding in their stomachs and the birds exploding. This has just never happened in all of human or bird history.

19. An earthworm does not become two earthworms when you cut it in half. If it’s lucky, the part with the mouth survives, and you’re left with one smaller earthworm. But most likely, you’ll end up with two dead earthworms.

20. Humans have more than five senses, including a sense of time, acceleration, and limb position. The five senses were made up by Aristotle, and as usual, he was wrong.

21. Shaving does not cause hair to grow back thicker or coarser, no matter where you’re shaving.

22. Your fingernails don’t keep growing after you die.

23. If you swallow your gum, it will not stick in your stomach for seven years. It goes through your body just like anything else you eat. Except batteries. Don’t eat batteries.

24. People don’t use only 10% of their brains. William James seems to have coined this one, but he was speaking figuratively.

25. You can’t catch warts from toads. But you can get warts from other people, which is why I always say: Only socialize with toads.

26. A penny dropped from the Empire State Building will not kill someone if it lands on their head. The terminal velocity of a penny is between 30 and 50 miles per hour, not fast enough to kill anyone.

27. Abner Doubleday did not invent baseball and in fact never claimed to have invented baseball.

28. Caesar salad was not invented by Julius Caesar but for its inventor, Caesar Cardini, who supposedly invented the salad in Tijuana, Mexico, in 1924.

33. Danishes are from Austria, not Denmark.

34. Humans didn’t evolve from chimps; we share an ancestor, but we did evolve.

35. It’s a chest of drawers, not a chester drawers, as I learned when I was 28 years old.

36. If you can replace “you’re” with “you are,” contract; otherwise, don’t.

37. The Italian libertine is Don Juan, but in Byron’s epic poem, he is Don Juan, rhymes with ruin.

38. You would not explode in the vacuum of space.

39. No one was burned at the stake during the Salem Witch Trials; 19 people were hanged and one was crushed with stones, but no burning.

40. Chinese fortune cookies are Californian, not Chinese.

41. Neither blondes nor redheads are about to go extinct.
