I was sharing a room at San Diego Con with a couple of comics nerds and Brad Pitt. Brad rearranged my piles of comics at one point and I got super-pissed.
Later, me and the other two comics guys were talking nerd stuff, miniatures or something, and I turn to see what Brad is up to and he's sexually assaulting a girl on the other side of the room, on one of the two queen-sized beds. At first I thought they were just engaging in rough play, but when I realized it wasn't, I leapt across the room and grabbed him. He started thrashing around, flailing like a wild animal. We wrecked the room, fighting. The fight was going bad for me, to be honest, but then hotel management showed up and broke us up.
