Who is your favorite football commentator, and who is your least favorite?

Who is your favorite football commentator, and who is your least favorite, either during the games, or not. I always like to listen to Michael Irvin (although lately he has been sounding a little cracky) and Warren Sapp -- they're usually insightful and funny as hell. Least favorite: Cris Collinsworth because he's creepy and the sound of his voice annoys me. Plus, I've seen that video from his playing days when he talked about how he used to like to hit on girls as young as 14 -- pervy!!!
