Clean-cut Don Draper Morphs Into Big-Bearded Jon Hamm At Sundance 2010

On TV, Don Draper is a slick, clean-cut advertising executive. The ladies love him (in real life too) and the men can only hope to emulate him. He's got flaws of course, but he keeps them well-contained. Jon Hamm, the actor who plays Draper, is at Sundance right now, to promote "Howl."

As you can see in the video below, Hamm is not so clean-cut in real life. Not right now at least. He ascribes it to how much time off he has. MTV's Josh Horowitz asks the tough questions though, probing to get to the bottom of why Hamm's beard seems to have triggered the end of all civilization as we know it. His answer might shock you. Or not.
