Watch Jon Hamm's Face Go From Don Draper to Goofball in No Time

It's Jon Hamm's 44th birthday this week, and we love him so much — 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 Saturday Night Live, and in real life. To celebrate the mad man, let's look at his most serious moments juxtaposed with his goofiest moments — in GIFs! Plus, in case you haven't checked out the totally '70s Mad Men pictures, you need to.
