Was that Biz Markie filming it?
I saw similar shit like this happen in downtown Seattle except it was some street bum skater kid and he was just crossing the streets when it said not to and swinging his skateboad around and the traffic would stop so they didn't hit him. I watched him do this for like five blocks when he just got smashed by someone in a mini van. Like he had to broken quite a few bones. People were all running over to help him, I just kept on walking. Fucker deserved it.
