I stole this from another board, but it sounds fun.
1. That we had to wear bike helmets bc we would become mentally retarded from falling. (My dad feels awful about this now, but he swore by it when we were little)
2. That bugs would come out of our hands if they weren't washed.
3. That if we didn't get good grades, we would end up like our neighbor who was a check out girl at Shop and Save.
