Everyone smile and say, “Photobomb!”

Jimmy Fallon enlisted Jon Hamm to help pull off a prank of picture-perfect proportions when the two pounced on unsuspecting tourists posing for photos while visiting New York City.

The best part? TV viewers got a hilarious glimpse of it all on The Tonight Show with Jimmy Fallon on Monday.

In the clip, folks checking out the top of Rockefeller Center were asked if they’d be willing to pose for snapshots that, they were told, were going to be posted on a website.

Natch, it was all a bluff as – unbeknownst to the hapless out-of-towners – Fallon, 39, and Hamm, 43, came out of the woodwork and uncorked all sorts of shenanigans.

There was no shortage of that: The duo piggybacked, chest-bumped, popped out from inside hidden bins and … well, see for yourself in the clip below.

Hey, sure beats a ho-hum tourist shot of Times Square.
