Jimmy Fallon and Jon Hamm photobomb NYC tourists

Jimmy Fallon and Jon Hamm went to the "Top of the Rock" to photobomb unsuspecting tourists as part of a segment for The Tonight Show starring Jimmy Fallon.

Once the two got to the top of Rockefeller Center, they had NBC staffers ask tourists to take a picture and then Fallon and Hamm jumped in the background. They jumped in the air, made ridiculous faces and even ate a hoagie in the background.

The tourists initially had no idea the celebrities were behind them but it's a safe bet they didn't mind the cameos.
