Jimmy Fallon & Jon Hamm's Amazing Photobombs

Jimmy Fallon had a little fun with people in New York City recently.

In a bit for his “Tonight Show,” Jimmy’s team asked people if they wanted to get their photo taken on top of 30 Rock, for NBC’s “Top of the Rock” website.

“We were lying,” Jimmy revealed to his audience on Monday night.

What came next was unsuspecting folks having their photos taken while secretly being photobombed by not only the “Tonight Show” host, but “Mad Men” hunk Jon Hamm. And it was all recorded for Jimmy’s show.

“That went way better than I expected, “ Jon quipped after he and Jimmy got in many pics – including one that involved a hoagie (just watch) – without alerting the people posing.
