1. A man named Edward Edwards went on the game show To Tell The Truth to talk about being a reformed criminal. But while he openly talked about having served time for robbery and arson, he neglected to mention that he was now actively a serial killer. He wouldn't be caught till 2009, over 25 years later.
2. Head over to the right alley in Shanghai, and you can eat live shrimp soaked in a soup of local liquor.

Pick them up with chopsticks, and chew them as they squirm in your mouth.
3. In 1934, a Canadian woman gave birth to quintuplets, and the government convinced her to turn them over. Their new doctor guardian created an attraction called "Quintland" out of them, keeping the children behind glass so 6,000 people per day could come to stare at them. This baby human zoo was the biggest tourist attraction in Canada, more popular than Niagara Falls.
4. Keep an eye out for chigoe fleas. They bite their way into your foot. Each bug balloons to the size of a berry, with their asses pointing out so they can spray eggs as you walk.
5. French company Gaumard has built a robot child named HAL for doctors to practice on. HAL bleeds when you cut it. HAL cries in pain. HAL calls out for its mother. HAL was "built to suffer," according to its French creators, who (did we mention) are French.
6. Nintendo avatars are called Miis, and they look pretty cute. Just don't think about how they're based on kokeshi, a type of Japanese doll inspired by child murder. In the Edo Period, parents would limit their families' size by killing unwanted infants after giving birth to them, and kokeshi were a memorial to these murdered babies.
7. More than once, people have jokingly stuck their heads in nooses in haunted houses and ended up hanging themselves.
8. The Japanese Imperial Army ate some of their prisoners of war. The country covered up over 100 cases of cannibalism, and victims who were murdered before being eaten were the lucky ones. Other victims, their captors kept them alive and sliced meat off them to eat a little more every day.

12. The town of Sagada in the Philippines has a tradition of hanging their coffins, so they line the faces of vertical cliffs.

Over the years, thousands have broken free from their ropes and dropped their deceased contents on the villagers below.
13. Ever hear the urban legend of the goofy Halloween decoration that turns out to be a dead body? That happened for real.

16. A man living east of Bangkok squatted over his toilet one day in 2016, and a python slithered up from within and latched itself to his dick. He managed to fight and kill the snake, which wasn't venomous, so this didn't go as bad as it might have. But still: a toilet snake bit his dick.
17. When a highwayman named George Parrot died in 1878, a doctor turned his skull into a doorstop and his skin into a pair of shoes. Wyoming's governor wore these shoes at his inauguration to show off how tough he was and then went on to become assistant secretary of state of the country.

21. Archaeologists in 2012 unearthed something terrifying: a bunch of bones! Specifically, it was a pit containing nothing but severed hands. This 3,600-year-old discovery provided evidence for the practice by which soldiers would chop hands off enemies and get paid for them in gold.

28. The Roman emperor Tiberius tied men's penises shut, so their bladders would burst.

The subject said he was relieved he hadn't gifted a crab instead, so Tiberius next had guards fetch a crab and use its claws on him.

32. Scientists are working 5,000 feet beneath the mountains of South Dakota. The supposed reason Sanford Lab is buried so deep is to "block ambient radiation."

Intrigued by tales of cannibalism, he bought a slave girl and sold her to cannibals so he could watch them rip her apart and eat her. He made sketches of the event. Later confronted by the media, he clarified that he'd made the sketches in his tent from memory, as the murder was too quick to draw.

41. Mexico's Knights Templar Cartel did all kinds of shady stuff until they disbanded in 2017. The worst was surely their practice of harvesting organs from schoolchildren. They kidnapped kids, took them to rented homes, and chopped them up. And no, they did not sew the kids back shut afterward.

49. A Chicago cemetery reserves a special section for circus performers. It began when two trains collided in 1918, killing 86 in the circus, but it's expanded since then. We don't know the official names of some of these clowns. Some headstones simply read "Smiley" or "Baldy."
