Watch: Barack Obama's witty reaction to man who tells him, 'don't touch my girlfriend'

Washington: Let's be clear: It was a joke. It unfolded while Obama cast an early ballot Monday in Chicago.

A young woman, Aia Cooper, was voting next to Obama when her boyfriend, Mike Jones, decided to make a wise crack: "Mr. President, don't touch my girlfriend."

Obama, laughing, replied: "There's an example of a brother just embarrassing me for no reason."

Cooper apologized. But Obama imagined how she would retell the encounter: "I can't believe Mike, he is such a fool. I was just mortified. ... But fortunately, the president was nice about it, so it's all right."

Obama gave her a kiss. "Give him something to talk about."
