Visitors to New York City's Top of the Rock — the roof deck of 30 Rockefeller Center, which offers stunning views of the Manhattan skyline — were in for a treat recently, when Jimmy Fallon and Mad Men star Jon Hamm teamed up to photobomb the unsuspecting sightseers as part of a Tonight Show prank.
One of Fallon's Tonight Show crew members was stationed on the rooftop with a point-and-shoot camera and offered to take pictures of visitors, who were told the shots would be used on NBC's website. (They weren't.)
As the groups and pairs were posing, Fallon and Hamm inserted themselves into the background of the photos, with antics that got more and more ridiculous as the day went on — including a Lady and the Tramp dramatization involving a hoagie.
