The West Wing
But Atrios did a good job, I think. I do think he should have looked at the camera, it's not a good idea to make the jump to TV and not use it to advantage. I know he's shy about his looks, but it just made him look geekier by trying to hide. I couldn't even hear his lines, he mumbled so softly.
I guess he'll learn in time. Maybe he can get an acting coach.
(and he really should do something about the namestealers running around on his site, I mean it's theft, like what Ben did but worse, it's identity theft.)
