1955 Looney Tunes Bugs Bunny cartoon, directed by Friz Freleng. The cartoon pits Bugs against Dr. Jekyll, who continues to turn into Mr. Hyde. The title is a play on the expression "neither hide nor hair."

Bugs comes out of his rabbit hole in a city park every morning, because a kind gentleman keeps coming to feed him a carrot. At first feigning a usual rabbit stance, Bugs eventually stands up and confides that he'd rather simply go home with the gentleman, since it would be easier on both of them. As the gentleman brings Bugs home, the camera pans up to see that the name above the apartment is for Dr. Jekyll.
