I had an alcoholic uncle who had a knack for saying crazy stuff. One time, he sneezed into a napkin, and exclaimed something like "Man, I think I just blew my brains out through my nose!" I totally thought this was possible until I was about 15 years old! Somehow, I also transferred this belief to other bodily functions, and whenever I had a particularly difficult to pass bowel movement, I was terrified that I would poop my stomach out of my butt!
