What is the name of the 80's cartoon short that had two characters in white lab coats? There was a tall thin man, and a short, more round one. The tall man had a wiry black moustache, very prominent nose and had a nasally voice, and I am unsure of any features for the short man, and I don't believe he talked at all. I believe the tall one was the main character, always messing up the experiments? While the short quiet one was the more intelligent one?
