President Barack Obama President Barack Obama

Note to the American people: Do not tell President Barack Obama he can't touch your wife or girlfriend, because he will punk you good.

The president was casting his early voting ballot in Chicago Tuesday among the hoi polloi, when a man named Mike Brown walked by and jokingly said, "Don't touch my girlfriend," referring to the woman, Aia Cooper, who was in the voting booth next to him, CNN.com reports.

Without missing a beat, the president said, "I really wasn't planning on it," and said it was a case of a "brother just embarrassing you for no reason." Obama went on to mimic the conversation that Cooper would have with Brown when the two got home. "I can't believe Mike. He's such a fool," Obama said, impersonating Cooper. "I was just mortified. But, fortunately the president was nice about it. So it's all right."

Obama decided to take the joke a step further and tried to make Brown jealous by kissing Cooper on the cheek, ABC's Chicago affiliate reports. "He gave me a hug and a kiss on the cheek, just the cheek," Cooper told the news station. "Please, Michelle, don't come after me, just the cheek!"
