Talk about taking the best picture ever!
Jimmy Fallon and guest Jon Hamm decided to have some fun on "The Tonight Show" with a few lucky New York tourists ... by photobombing their pictures at Rockefeller Plaza.
Check out the hilarious video above to see the great poses the guys make!
Jon's expressions are seriously priceless, and we love how he and Fallon coordinated their stunts for the fun photos.
We only wish we could see these tourists' reactions when their got their Rockefeller snap back! What do you think of the late night host and the "Mad Men" star's prank?
