Because my friend's tooth fell out.
Here's what happend, we were talking then all of a sudden his tooh fell out and I said "what was that" and he said "Oh, my tooth..." And he said it like no biggie.
ANd then in CPR class there's this FAT girl who volunteered to lay on the floor and the teacher said to the other volunteer "Put your finger on her chin"
And someone in the background loudly said "Which one??"
