Justin Bieber continues to keep things butch with his new fragrance, Someday, the ad for which sent the Beliebers into fits of ecstasy a few weeks back. Now, Bieber is making fun of himself, his commercial, and fragrance ads in general with the parody spot below, co-starring Jimmy Fallon (from the latter's NBC talk show). I was expecting the worst, given the participants, but the video is funny and well-crafted. Fallon playing Bieber's adulthood is sad and hilarious and accurate in too many ways to list here. It was odd, though, to see him doing comedy without corpsing every 10 seconds.
