We love to learn facts: fun ones, cool ones, strange ones. The internet is a treasure-trove of new facts to discover and share with your friends. On the other hand, it also brings us some things that we wish we didn’t know.

Have you ever heard a fact so weird and specific that it made you ask, “Why the hell do you know that?” Apparently, quite a few people have. A recent thread on r/AskReddit set out to find the strangest facts that people know and the internet has delivered once again.

Tell one of these facts to someone and it will surely bring a look of horror and confusion to their face. So, they’re probably not the best icebreakers to use at a party, but hey, maybe they’ll be useful at some point in the future. Check out part one here for more weird facts.

There’s a whole slew of random and weird facts shared on the thread. BeefBall1010 told us that the one about rats was a personal favorite of theirs. Most of them are quite memorable ones but trying to remember every single fact you’ve ever heard can be quite a challenge.

You have erectile tissue in your nose. Orcas are the biggest natural predators of moose. There is a psychological disorder in which people believe they are a cow and it's called boanthropy. A wood frog can hold it's pee for up to eight months. If you keep a goldfish in the dark, it will lose it's colour and become white. You can actually "dig to China" from Argentina. The Mona Lisa doesn't have eyebrows. There is a kind of psychologist called a "wealth psychologist" that specializes in helping wealthy people deal with immense guilt or not being emotionally able to cope with being rich. A single spaghetti noodle is called a spaghetto. A Polish doctor faked a typhus outbreak in order to prevent nazis. The youngest Pope was only 11 years old. A man once filmed 7 episodes of a soap opera in IKEA without getting caught. (the opera). Pigs will eat the entire human body except for the teeth. When cremating a body, if you don't remove the teeth, they will pop like popcorn.

One way of recounting information is the use of mnemonics. This refers to a system that can help you remember information by tying it to certain patterns. Examples of this can be acronyms (such as ‘Every Good Boy Deserves Football’ that musicians use to remember the lines on a music ledger) or musical methods (like putting the alphabet to the tune of ‘Twinkle-Twinkle Little Star’). Surely a lot of us still recount the alphabet by using this method, I know I do.

An experiment was performed on how mnemonics such as acronyms can make a difference in remembering information and enforcing our work without interruptions. It required the 65 participants to complete a task with multiple different steps. Half of the group were given an acronym to support and remind them of each step and the other half were not.

40 ‘Why The Hell Do You Know That’ Facts That People Probably Shouldn’t Have Shared But Did Anyway When Napoleon Bonaparte died in exile, they cut off his reproductive organ and gave it to the local parish priest. The priest later sold it to raise money for his Parish and it's been sold and resold down through the centuries and to this day there are three people who claim to own Napoleon's reproductive organ.

No one knows why this happened, and it's not the important part of the story. The important part is, who the hell do those other two belong to?

Results from the experiment showed that those with the acronym fared far better than their counterparts at completing the task. It was linked to the participants being able to perform and recover faster after being interrupted as part of the experiment. The sequential steps made it easier to visualize the steps in their minds and reinforce what needed to be completed next.

40 ‘Why The Hell Do You Know That’ Facts That People Probably Shouldn’t Have Shared But Did Anyway Rats are bisexual by nature and females will have group orgies with each other when in heat.

Male's balls can take up 10% of their entire mass!

There was a study where they put females in 'lingerie' and accustomed the males to it to the point they only saw the lingerie wearing rats as suitable mates.

Rats can give into peer pressure and eat things they don't like if everyone else is eating it.

Rats cannot burp or vomit.

With the amount of people killing pest rats by poison, they are creating bigger, smarter, poison resistant mutant rats.

Another more visual way of memorizing information is the 'method of loci' or the use of a ‘memory palace’. This was used to effect in Benedict Cumberbatch’s modern portrayal of Sherlock Holmes, where he closes his eyes and imagines a virtual space that stores all of the most useful information in his memory. All he had to do was walk through the space led by certain cues and pluck out memories from wherever he had filed them, helping him to solve cases in a jiffy.

Another random law: If a Swede crosses over the frozen sea between Denmark and Sweden, Danes are allowed to beat them up. It's a relic of when Denmark and Sweden were constantly at war, so if a group of Swedes crossed over the ice they probably didn't have good intentions, thus this law allowing the Danes to defend themselves. As far as I know, it was never changed.

Perhaps the most outstanding champion of the competition is Dominic O’Brien. Having won it a staggering eight times, he’s gone on to write about memorization techniques and even developed his own system.

O’Brien spoke with The Daily Mail about his use of 'loci' and how it helped him to win the titles so many times. He said, “This is undoubtedly the key to my success at the World Memory Championships. Placing each piece of data that I had to absorb in a particular place that I had already set aside in my mind made it easier for me to recall them.”

O’Brien explained how we already use loci: “An excellent everyday example of the art of location is the solution to the common problem of finding a set of misplaced keys. What we do is retrace our steps (logically or figuratively).”

“We check the hall where we hung up our coat when we first came home, the study where we went to check phone messages, and so we continue through the house until we eventually arrive at the place we put down our keys.”

A botfly egg can land on your skin and implant within a fraction of a second. If one hits you in the eye, it is possible that it can implant the egg under your eyelid so your eye incubates and subsequently feeds the growing larva.

According to archeological evidence, the Aztecs basically discovered through their years of sacrificing people that it’s way quicker to cut open the stomach and then go up and under the rib cage to cut the heart out, rather than trying to break open the ribs to get through them. They could apparently get someone’s heart out this way in only a few seconds, and there are accounts of sacrifices where multiple thousands of people had their hearts cut out in a single day, which would take forever if they didn’t know the quickest method.
