What did you do as a child that you now find terrible or embarrassing? I'll start.

I was painfully afraid of members of the opposite sex. I went to a Halloween "party" when I was 12 thrown by some friends (parental supervision, obviously). There was one guy-bigger, shy-who finally mustered up the courage to ask me to dance and I lied and said my ankle hurt. Then I made my friend's mom drive me home...fail.
