I always stay behind and read the movie credits. :) Welker's shown up in almost every cartoon series I've ever seen, and he does vocals in live-action films as well. I don't know his email address; I can't even find signs of a fan club. Odd. Here's a couple of mailing addresses, though. They were posted in Welker's entry on the Internet Movie Database. Maybe you can reach him through one of these: 10635 Santa Monica Blvd. #103 LA, CA 90025 26500 W. Agoura Rd #600 Calabasas, CA 91302
