Jon Hamm played with his buttons on his way in to tape The Late Show with David Letterman in NYC yesterday. His interview doesn't air until Friday, but it must be an interesting week to sit down with the talk show host. To tons of fans, Jon is basically one and the same with his character Don Draper — case in point, AskMen just named Draper as the most influential man of the year. It's quite the compliment to Jon's acting, and we're looking forward to seeing him outside of the world of Mad Men, especially alongside also sexy Ben Affleck in The Town.
