Jimmy Fallon and Jon Hamm surprised sightseers today at the famed "Top of the Rock" at 30 Rockefeller Plaza, where The Tonight Show is filmed.

The visitors were told they were getting their picture taken, but what they didn't know was that behind them, Hamm and Fallon were photobombing them in pretty hilarious ways. ("The Hoagie" or the "Lady and the Tramp" = I DIE.) Plus, all the unsuspecting participants got a copy of their photo afterwards. Can you imagine what you'd do if you saw Jon Hamm's beautiful face jumping around in the background of one of your family photos? That is magic, people.
