When I was a kid, my older brother told me that in Japan, they don't have toilet paper. Instead, they have a whole in the wall. You would wipe with your hand, and then stick your hand in the wall only for someone employed on the other side to hit your hand with a brick. This would make you stick the hamd in your mouth - all clean!
I believed this until I was about 12 when I was watching a travel show, showing a motel in Japan - with NORMAL toilets!! haha
A childhood belief about general

- I used to think that my right hand wasn't my right hand anymore if I turned around.— Mike
- Pink Floyd- Brick Wall.
I used to believe it was "we don't need no fart control" in the second line there.— Norwegian Dude From Kopervik - I used to think the line in Pink Floyd's Another Brick in the Wall was "No dogs allowed in the classroom."— Gretchen
- When I was small, my brother would bug me and say that if my hand was bigger than my head, I had a tumor.Anon
