This has been going around, from Esquire:

“I hope this isn’t too personal,” I said to [John] Edwards, “but I was reading about how Elizabeth discovered her cancer this second go-around. It was a broken rib, correct?” “Yes,” Edwards said. “The papers said you were hugging her — which is always nice to hear, a married guy hugging his wife. It must have been bizarre. What happened, you just hugged her and heard a snap?” “Maybe it is a little personal,” Edwards said, laughing self-consciously. “Maybe I don’t want to know?” “It was a perfectly reasonable question,” he said, bailing me out. “So hugging was perhaps a euphemism?” “That’s my story, and I’m stickin’ to it,” he said, raking his forelock with his fingers.
