Billy West also voiced Skeeter's dad (Joe Valentine) and Coach Spitz
Mentioned it a few years ago:

And I've seen him credited as the voice of "Boomer" on another website.
Strange that he isn't credited as such on IMDB. What I want to know is who did the voices for "The Beats" and how many people got involved with the music for the show. I know Fred Newman and Dan Sawyer were the two main ones credited for the music, but I wonder if Billy West also got involved (aside from the obvious times when he was doing Doug singing or rapping or whathaveyou), because he has mentioned more than once that before he started voice acting, he was a musician and played guitar. Plus, he's a vegan...and he mentioned in one interview that tofu is an absolute staple of the vegan diet.
Coincidence that The Beats' first song was Killer Tofu? I wish I could meet him and ask him about that.
I know the lyrics to "Killer Tofu" were written by one of the show's writers, Alan Silberberg (per his website).
