Best known for his hilarious, hard-drinking, reality-ish Comedy Central show Insomniac, Dave Attell is apparently sober but not quite walking the straight and narrow. These days, he’s got a show on Showtime called Dave’s Old Porn. He calls it “The Mystery Science Theater of porn”: Attell and foul-mouthed comedian pals like Chelsea Handler, Adam Carolla and Jim Norton sit around watching ’70s and ’80s stag films and laugh/gag at how hairy everybody was. His standup act, meanwhile, remains as beautifully harsh and self-deprecating as ever.
