Well, to be fair, doesn't sound like Chuck had a chance, considering he was TOTALLY not expecting any sort of attack. Guy thought he was there simply to exchange pleasantries.
Not to suggest Mike wasn't a beastly mutha, of course. But if Norris had had ample warning, the result might have been, how shall I say, more blustery?
Regardless of who the eventual "winner" might have been, it's safe to assume there would have been a substantial dust-up. Chuck is a tough SOB.
