I knew a guy in school whose wallet was stolen. Later that day he was at work - he worked retail, and helping a customer ring up a large sale. He looked at the credit card - it was his! He excused himself for a second and walked back to call security - cool as hell. He returned and continued to ring up the sale while security arrived. He then accused the thief, which the guy denied. The response? Dude, that's MY name on the credit card.
