I'm a PC

PCs have just about had it. Mocked relentlessly as stodgy and passé in those John Hodgman/Justin Long Mac ads, PCs are fighting back! Significantly funnier (and possibly cheaper) than the much anticipated, ultimately flat Bill Gates/Jerry Seinfeld ads, this spot finds real people of all sorts to give PCs a plug. Naturally, Gates is in there somewhere, but he's got nothing on the dude in the shark tank ("I'm a PC. And I'm kinda scared") or the incredibly random gentleman at the end, who just wants us to know that he's a PC and he sells fish. We're sold on this commercial.
