I was watching the Simpsons season 6 on DVD, the episode called "Bart of Darkness" and one of the people doing the commentary said something about the guy known as Dave Seville that he was in some movie with Jimmy Stewart. I think it was called Last Resort where he's got a broken leg and is watching people out his window or something like that. They also said that he recorded Witch Doctor first then added the Chipmunks but I'm sure you all know those stories. At least Snowseph, our resident Chipmunk stalker, should know.
