It's Jon Hamm 's 43rd birthday this week, and we love him so much, and it's not just because he's played a character who's become so important to pop culture. We're so used to seeing Hamm as Don Draper on Mad Men  that when he steps out of the suit, it's a novelty, and lucky for us, Hamm tends to get goofy in movies like Bridesmaids, on SNL, and in real life. To celebrate the mad man, let's look at his most serious moments juxtaposed with his goofiest moments — in GIFs!
