He also appeared on Robot Chicken and Family Guy, reprising some of these roles.
- He is very good friends with Peter Cullen, and they sometimes do interviews together. This is despite the fact that they play the worst of enemies on TV.
- He also voices Soundwave in Italian. Wow.
- He has been Fred in every form of Scooby-Doo media ever save for the live-action movies and the version where everybody is a kid.
- One time, he voiced for Yoshi! Unfortunately, it was only in the movies, so yeah.
