by Dannica RamirezBuzzFeedBuzzFeed Staff I don't know about anyone else, but I love learning interesting, bizarre, and straight-up weird facts about anything and everything. (In fact, it's quite a conversation starter.) That said, here are some wacky, intriguing, strange, and somewhat funny facts that sound somewhat fake but are entirely true: 1. In the 1960s, the CIA launched "Operation Acoustic Kitty," an effort to train cats to become foreign spies by implanting microphones in their ears and radio transmitters at the base of their skulls.

Rather than farting, the gases are reabsorbed into the bloodstream and are then respired out of the lungs.
Talk about morning breath. 8. There are caves in Missouri that store 1.4 billion pounds of government-owned cheese. Located deep in the Ozark Mountains in limestone-converted mines, the caves are kept at a perfect 36ºF. As someone who's lactose intolerant, my stomach is in knots just thinking about it. 9. This one actually made me do a double-take: Cornflakes were invented to suppress sexual impulses and desires. Steven Gottlieb / Getty Images John Harvey Kellogg invented cornflakes in 1894, but it was later used as part of an extreme diet promoted by his church to basically suppress horniness. Kellog thought sex and masturbation were abnormal and unhealthy, so he believed cornflakes - and their lack of flavor - would help fight off any desire. 10. Cockroach dust plays a part in why so many inner-city children have asthma. 11. A single cloud can weigh about 550 tons or more. 12.

In Switzerland, owning only one guinea pig or parrot is illegal. 17. If you're drunk or violent in Japan, police will take a plastic sheet and roll you up like a burrito. Sopa Images / Getty Images Police in Japan rarely ever resort to violence, as they choose to de-escalate the situation at hand first. After the wrapping, police will take the drunk or violent person to the station to let them calm down. 18. If they wanted to, clownfish could change their sex, including reproductive organs, through an irreversible process. 19. No one commits to the bit better than Toni Collete.
