Dave Coulie (sp) from Full House voiced Baby Animal (I hear it used to be Howie Mandel, but he Quit for Some reason). Stitch was voiced buy Chris Sanders, who used that voice to annoy co-workers. He did the voice, because He couldn't see any Celebrity mumbling in a baby voice like that.
However, my impersonation of Stich is exactly the same as my Animal impersonation. Maybe because I'm a lousy imitator.
At least my "Bullwinkle" sounds good!
