I got slapped right across the face at my 8th grade dance.

First of all, in hindsight, I don't even know why I went to my stupid 8th grade dance.  I was probably the least likely person in my class of 11 to go.  I certainly didn't plan on asking anyone to dance, that's for sure.  After standing around all night staring at the disco ball, I was finally asked by a girl to dance.  It was obviously a pity move.  I slow danced like a dork through the long version of "You Light Up My Life" without embarrassing myself too much. 

Then, as it ended, one of the other guys said something like "Dave!  I can't believe you just did that!"  The girl I was dancing with stopped and said "What did he do?"  He told her that I had cupped my hand under her ass like I was gonna grab it.  Then she slapped me right across the face and pushed me away.  Everybody got a huge kick out of it.  The weird part of it is that she had to know that he was lying and that I didn't do it.  I wonder now if she was part of the setup.
