Stand-up comedian Dave Attell made a real name for himself with his Comedy Central show 'Insomniac: With Dave Attell' in the early 2000's. Since the end of the show in 2004, Dave has returned to his traveling stand-up gigs, making regular USO tour appearances, hosting the Adult Video Awards, and had his short lived 'Gong Show' on Comedy Central. Now the stringy haired, alcohol driven, comedian returns with Showtime's 'Dave's Old Porn' which combines comedy and old 70's porn.

Attell, talking about the show with Conan O'brien, described it as: "It's like a Mystery Science Theater...but with porn." Check out the entire chats with Conan below.
