I've just been reading the spoilers for this year's Royal Rumble. Now, Vince McMahon isn't a wrestler. He wrestles now and then, but he doesn't actually have any wrestling training beyond falling properly. This usually results in his matches being what they call 'bloodbaths' with his opponent beating the living hell out of him with weapons, or throwing him through things. That's pretty much how they make matches with non-wrestlers interesting.
So Vince has all sorts of crazy shit happen to him. He's bled like mad, been beaten over the head with a bedpan, had someone kick a garbage can into him from the other side of the ring, etc etc. Last night at the Royal Rumble he suffered his first legit, major injury. He blew his knee out. Walking down to the ring. How fucking unlucky can you get?
