Apatow has recently refound stand-up as a passion after ditching it for nearly 25 years. In that time, he made hit films, like The 40-Year-Old Virgin, Knocked Up and, most recently, Trainwreck. So, we're not that upset, but we're happy he's back on the stage with a bunch of friends—and he's really funny. Need proof? Check out his set on TheTonight Show Starring Jimmy Fallon.
