Yesterday (September 19) was Jimmy Fallon's 40th birthday, and the crew of "The Tonight Show" pooled their money and got him something extra, super special: a giant cake! What was inside that giant cake? A shirtless Seth Rogen and James Franco, of course.

Clearly, Fallon had no idea what skin-baring surprise was coming his way, because he was left speechless. He also laughed so hard that breathing became an issue for him.
