You ’ve got to study it to believe it .

Last month, we asked theBuzzFeed Communitytoshare interesting factsthat amaze people whenever they tell people at parties, and I’m still trying to pick my jaw up off the floor.

Here are just a few of their submissions :

1.“A city in the Czech Republic had been preparing to build a dam. The project was going to take about a year to complete. However, a bunch ofbeavers got togetherand built the dam in two days, thus saving the local authorities about 1.2 million euros.” —jmacxjr

2.“The guy who [originally] playedMichael MyersinHalloweenhas/had a cat named Michael Meowers.” —thehallouminati

3.“Most European languages haveforgottenthe original word for ‘bear’, replacing it with either a word meaning ‘the brown one/Mr Brown’ (as in ‘Bear’) or ‘He who eats honey’ (as in the Slavic ‘Medved’). This is because the original, forgotten word for ‘bear’ became taboo, due to the fear of summoning a bear if its name was spoken.” —Sasha Kyääti

4.“Eighty to 90 percent of US dollar bills arecontaminatedwith cocaine.” —Lita Rose

5.“Wombatspoopcubes.” —lunastardust365

6.“I named my first wife. To be precise, when she turned 18, she decided she wanted to legally change her name. She never liked her first name, and her last name was that of her mother’s second husband (she wound up with five). So, the two of us contemplated names, and in the end, I came up with the first and last name she still uses today, more than 40 years later.” —parryboucher

7.“Birds are scientificallyclassified as dinosaurs. Dinosaurs as a whole aren’t extinct.” —eclipsecat

8.“I was almost killed when I was 11, playing hide and seek. I hid in the outdoor trash can UNDER the trash so if my friend looked, he wouldn’t see me. I was under there for a LONG time, so I was debating whether or not to come out. I ultimately decided to get out, and when I did, the trash truck, which I had not heard, had a claw extended out to the trash can and would have dumped the trash into the compactor seconds later. If I hadn’t gotten out when I did, I would have been smashed to death.” —lazygamer141

9.“A horse’s teethkeep growingtheir entire life like fingernails, and most must have them filed down yearly to prevent sharp edges. They also chew side to side instead of up and down, which helps to grind them down.” —Peyt
