I've been browsing around Bored.com tonight looking for something funny, and came across this site: http://www.iusedtobelieve.com/
It's got submissions from people telling of strange and funny things they believed as a child. Here's an example of one...
"I had a strange fear that if I closed my eyes in the bathtub, William Shakespeare would come up through the drain and kill me. I knew his name, but I had no idea who he was, so I just naturally assumed he was some sort of bathtub vampire.
Some are hilarious, so everyone HAS to go there and read them. It makes me think of strange things I believed as a kid, and makes me wonder if I thought any crazy stuff that I don't remember now.
Anyway, I'll see everyone later.
