I'm not saying what Punk did was right, but that guy TOTALLY deserved what he got and then some. Much better video here if no one's posted it yet:
EDIT: Hang on, watch real close, Punk's head gets shoved forward by the guy behind the guy with the glasses. He wormed his hand past the guy with the glasses and hid back behind him real quick. I think the guy with the glasses got him the first time by accident, it looked like he was trying to move to that spot he was standing in and bumped into Punk(or Mr. Middle Finger pushed Mr. Glasses), and then that guy with the middle finger behind Mr. Glasses got him the second time.
