Can we all just take this as proof that when Mad Men ends after season seven, Jon Hamm's next gig should be "regular guest on The Tonight Show Starring Jimmy Fallon"? Because this clip of him and Fallon photobombing tourists on the roof of 30 Rockefeller Plaza is kind of gold, and more videos like this need to exist in the world.
As for the concept behind the video—it's fairly simple. Jon Hamm and Jimmy Fallon teamed up to photobomb people, so they set up a camera on the roof of 30 Rock and had a photographer tell people that their photo would be posted on the 30 Rock website. They were lying, though, because the photo was really used for The Tonight Show, and they all featured Hamm and Fallon doing something hilariously insane in the background. Like chest-bumping, or eating a hoagie.
