I was listening to a radio interview with him the other day and it turns out that he is a (I think pro) MMA fighter.
He told a fucking funny story... He was at a bar with Chuck Liddell. Some random guy who they casually know was asking Chuck if he could be a good MMA fighter.
Chuck looks, shakes his head at him and said something to the effect, "You really don't get it... I LIKE hitting people!"
It was the way he said it that made it so fucking funny....
