Jimmy Fallon turned 40 years of old yesterday and to celebrate, people at the Tonight Show office arranged a special surprise for him, inviting his two sexy friends to dance out of a cake. Seth Rogen and James Franco shake it for the show host, but only as a sensual preamble for the real surprise.

Franco and Rogen called music legend Stevie Wonder to the stage to sing Fallon "Happy Birthday," and it brings a look of unparallelled joy to Fallon's face. Happy birthday, you goofy man.
