No Love Lost: B.J. Penn vs. Nick Diaz Weigh In Video

I'm not sure if anyone expected this scuffle between Penn and Diaz Friday Night at the UFC 137 Weigh In's. Either these are two guys who need to develop some sort of hate for each other before engaging in violence tomorrow night or there is a legitimate disdain that has developed over time between Penn and the Cesar Gracie camp and student.
