Here we have "The Night Before Christmas" as read by a whole bunch of voice actors including Gary Owens, Tom Kenny, Brian Cummings, Jim Cummings, Eddie Deezen, Grey DeLisle, Candi Milo, Billy West, Jennifer Hale and Don "The Movie Trailer Guy" LaFontaine. I believe Jim Cummings is the first person I've ever heard do an impression of Professor Irwin Corey. I'll bet there's a lot of call for that.
