People Share Their Best ‘How The Hell Do You Know That?’ Factoids


We all love a good fun fact.

They expand our mind just a tiny, gentle amount. Sometimes they bring a smirk to our face. And other times they’re reliable as hell during an awkward ice breaker.

So it’s not a bad idea to keep a few in your back pocket for when, say, you’ve just started a job or a first date is going horribly.

Thankfully, Redditor pygmypuffonacid was looking out for us when they asked:

“What are some ‘why the fu** do you know that information’ facts?”

Of course, you can’t go wrong with animal facts, like this one about squid. 

“Squid can literally give themselves brain damage by eating something too big. Their brain is a donut shape and the esophagus runs through it.” — orbitofnormal

Or this one, about a crustacean. 

“Crayfish (or lobster?) have a sort of open channel like an ear that helps them balance. A few grains of sand sit in it and because gravity is pulling the grains down they always know which way is up.”

“However if you put magnetic metal shavings into the holes and hold a large strong magnet above them they’ll start to swim upside down.” — XamiaArc

And do not forget about whales.

“only 10% of a whales sperm enters the mate, 90% goes into the ocean. meaning that drinking ocean water is drinking a percentage of whale cum” — SugonmaBalls

But of course, human bodies are just as bizarre. 

“Leave a human body soaking in a solution of lye and water for several months and it will dissolve into liquid and soft bone dust which can be washed down a drain, leaving no evidence behind.”

“If you need to speed the process up you can heat the water up to just short of boiling and dissolve the body in ~6 hours.” — hananobira

Same goes for human desires.

“Some foot fetishes occur because the part of the brain that controls feeling in the feet is positioned right next to the part that produces libido, and sometimes the wires within the brain become crossed.” — S_is_for_Smeagol

And how about a fact involving humans and animals both. 

“When someone dies in an area where insects can get to them, their face often decomposes first. There’s lots of nice holes on and next to the face that are great for egg-laying.”

“Then, the bugs eat your face and buzz off.” — tapiocatsar

History tidbits are always fascinating too.

Take this beer saga, for example.  

“That Rolling Rock beer almost went bankrupt in the 1990’s. As a last ditch effort they hired a new marketing exec to turn their fortunes around.”

“In their big meeting with all the board members waiting in anticipation for his big reveal he told them to just raise the price. They were ready to fire him on the spot, because they couldn’t sell any at the cheapo price.”

“Then he told them why – their price point was less than Budweiser at the time and that was the standard by which people judged the quality of a beer. He reasoned that if they increased the price to the next tier above Bud and did nothing else, people would believe it was a better beer, even though it was the same as it ever was.”

“It turned into their ad campaign and they thumbed their noses at all the yuppies who drank it by the case in college in the 70’s and 80’s who started buying it again because it was now a ‘better’ beer. It was wildly successful and saved the company.” — Finklemaier

Not all men from history are so admirable, though.

“Andrei Chikatilo, a serial killer from the USSR who was convicted of sexually assaulting and murdering at least 52 women and children, was arrested and questioned by police six years before his official apprehension date.”

“This was because police took a blood sample from him that was different than the blood group of the semen found at the scene of one of his crimes. However, obviously, Chikatilo was guilty.”

“He had a rare genetic condition in which the blood groups of his blood & saliva and his semen are different, which is how he was questioned and released.” — sylveonstarr

This guy was awful too. 

“John Kellogg (inventer of corn flakes) was a huge advocate for circumcision because he believed it would prevent us from masturbating.”

“Also he tried normalizing putting acid on the clitoris for the same reason” — TrystenConn

This guy, on the other hand, was just so unlucky. 

“Valery Khodemchuk was an engineer working the Night Shift at Chernobyl’s Reactor 4 the night it exploded.”

“He was the very first person killed in the accident, as he likely died instantly when his body was vaporized by the blast. His remains were never recovered, and the ruins now serve as his tomb.” — TheMadmanAndre

And this fella was off his rocker. 

“Opicinus de Canistris, an Italian priest who lived during the 13th and 14th centuries, believed that parts of his body metaphysically represented regions of the world, and that if he felt pain in one area, then it could mean that disaster was about to fall on that region.”

“He also drew a metaphysical “world map” that was basically pictures of random people and animals stuck together instead of an actual map of the world.”

“He actually managed to get the Pope at the time on his side. It speaks volumes about the state of science in the Middle Ages that this blatant psychotic could promote his beliefs under the guise of serving Christianity.” — ugagradlady

This fact concerned a fictional guy. 

“In Silence of the Lambs, when Hannibal Lector gives the infamous quote ‘I ate his liver with some fava beans and a nice Chianti,’ it’s a reference that he’s off his meds.”

“Some antipsychotics have negative interactions with beans, red wine, and organ meats. It’s kind of an odd joke though, because Hannibal Lector is a diagnosed psychopath in the movie, and psychopathy isn’t treated with antipsychotics.” — [deleted]

Here’s hoping these facts aren’t too unnerving to dust off at a party or a team-builder.
