Watch Jimmy Fallon and Jon Hamm Hilariously Photobomb Tourists at 30 Rock (Video)

The two jumped into the photos of unsuspecting tourists

Ever have the sinking suspicion that some snarky famous person is mocking you behind your back?

For a segment on “The Tonight Show” Monday night, host Jimmy Fallon and “Mad Men” star Jon Hamm jovially snuck into the background of some unsuspecting tourists’ photos at the top of 30 Rockefeller for a skit called “Celebrity Photobomb.”

“We asked people if they wanted to get their photo taken, we told them it was for the Top Of The Rock website,” Fallon explained. “We were lying!”
