At a recent breakfast event with reporters, James Carville responded to an inquiry about President Barack Obama's toughness by saying "If Hillary (Clinton) gave up one of her balls and gave it to Obama, he'd have two."

Appearing on 'John King USA' (weekdays, 7PM ET on CNN), Carville refused to back away from the "joke."

"If I offended anybody I'm not sorry, and I don't apologize," a snickering Carville told King. " It was the repeating of a joke, and, apparently, people laughed at it."

So far, neither Obama nor Clinton has commented on this most unconventional of junk touching.
