Chess Boxing

I kid you not:

One man makes his move, and respectfully looks up to the gentleman seated across from him. The second man pensively nods his head in recognition of a good move. He thinks to himself: One more move like that will bring about a checkmate, unless I can...

Then they stand up, don a pair of gloves, and proceed to beat the living crap out of each other while others gape in horror! In a few minutes, the first man falls unconscious to the floor. Man number two walks away a champ in spite of the impending checkmate against him.
