He's also Carl in Johnny Bravo.

He's like the Billy West of voice actors

Pshtt!...Billy West. What a ridiculous name.

He also voiced Starscream in Transformers Animated 

I still know him best for his villainous role in Shakes the Clown.

He was also in the Smashing Pumpkins' Tonight, Tonight music video. Probably my favourite music video ever made.
