So, basically, this dude in gray hid behind another guy, who was in a face-to-face spat with an old head, until he thought the time was right to hit old head in the face. Without old head having a chance of defending himself.
And everybody else started hooting and hollering in support, dumping water on and going into the knocked-out guy’s pockets.
UPDATE: Well, should have figured that’d get taken down with the quickness. Check Deadspin’s Tuesday Night Fights. Maybe it’ll surface there.
