Back when the remake of Battlestar Galactica was on the air the showrunner Ronald D. Moore had a podcast where he’d sip some scotch and smoke a couple cigarettes and provide commentary for the episode. It worked really well, and got me to watch the show twice because I wanted to follow along. Eventually they made it onto the DVD/Bluray releases as commentary audio tracks.

With the growth of podcasting I’m amazed other shows haven’t done something similar.
