Looney Tunes - Volume 3
Granny lets Bugs Bunny come in from the cold, but her dog Sylvester will have none of it. Elmer Fudd is a mad scientist who wants to turn Bugs Bunny into a fiend. Bugs tricks this ersatz Dr. Jekyll into drinking his own mixture; later, each thinks the other has changed into a bear. Bugs Bunny tricks Elmer Fudd into believing his house has been quarantined for something called "rabbititus."
