If the fact that the main event is Georges St-Pierre vs. Nick Diaz didn't already make you want to check out next Saturday's UFC 158 event, then this media conference call sure will. For a while now, Diaz has been peppering St-Pierre with jabs about his privileged lifestyle, but GSP has kept a cool head...until Thursday when the Welterweight Champion had about enough of his opponent's games and confronted him. With plenty of f-bombs and other curses, this is definitely not a family-friendly argument you're about to hear.

Head over to the 25:00 mark to hear them both really get into it.
