Who knew that Bob Saget,that clean-scrubbed patriarch of the G-rated family sitcom Full House, was in reality such a joyously filthy scumbag? The man once taunted as "Bob Faggot" in grade school has had a huge career renaissance lately, thanks to turning in one of the dirtiest performances in the dirty-joke movie The Aristocrats. (He also plays a bong-hitting parody of himself on HBO's Entourage.) His stand-up material would make even the Olsen twins blush. For example: "Girls go, 'Oh, my God, I grew up watching you,'" he told Rolling Stone recently. "And I go, 'Good. Now you've got to go down watching me.'" He's also working on a new HBO show in which he plays a single gynecologist, as well as an R-rated parody of March of the Penguins. Aw, Dad! Saget takes the stage today at 8:30 p.m.
