In the S1E06, I think it's called Belief, there's a song that Ali G uses in a video he makes to try and market to TV execs. It's actually just been used in a car commercial too, I think. I have a clip of it on my web site taken from the Ali G show. If anyone knows the name of the song or the artist, that'd be awesome. The quality of the clip sucks ass, just so you know.
