Mickey Rourke Talks Arm-Wrestling Injury on 'Late Show' (VIDEO)

If you star in a film called 'The Wrestler' there's an occupational hazard along with it, as Mickey Rourke explained to David Letterman on the 'Late Show' (weeknights, 11:35PM ET on CBS).

While in a pub in London, the 'Iron Man 2' actor hit it off with a team of burly rugby players.

"We were drinking tequila and one thing led to another, and we started arm wrestling," said Rourke. "I did OK with two of them," but then a man the "size of a house" took him on. Rourke beat the bloke with his stronger left, but with his right... quite a different result.
