This is what happens when Stone Cold Steve Austin punches you in the face ... for real.
Stone Cold accidentally clocked MMA fighter Paul Lazenby while filming a movie called "Damage." Steve felt so badly about throttling Lazenby's face and giving him black eyes and a broken nose, he mugged for this shot of the two of them -- sling, ice pack, and all. Austin, needless to say, wasn't actually hurt.
Lazenby tells TMZ, "I want to stress that this was NOT a case of negligence or incompetence, just one of those things that can happen even between skilled performers when they're swinging their fists at one another. I don't blame Steve at all."
So now you know.
