I used to believe

I was listening to the radio this morning and they made a little comment about this website. It's called http://iusedtobelieve.com/ . It's just a fun website, where people tell something they used to believe (usually as a child) and it makes for some good laughs. Do you have any good stories of what you used to believe? Feel free to share them if you so desire. :)

Here's something I used to believe: When I was in kindergarten, I used to believe that my vanilla yogurt was Elmer's glue and wouldn't eat it. I thought my mom was mean to give that to me as part of my lunch. Why would she give me glue to eat?
