Looney Tunes - Bugs Bunny - Hyde and Hare (1955)

Hyde and Hare is a 1955 Warner Bros. Looney Tunes cartoon, directed by Friz Freleng. The short was released on August 27, 1955, and stars Bugs Bunny. The short is based on Robert Louis Stevenson's 1886 novella Strange Case of Dr Jekyll and Mr Hyde. 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."
Allusions:
In the cartoon, Bugs sits down at a piano, places a candelabra upon it, and utters the phrase, "I wish my brother George was here". The reference was to Liberace, who had a brother named George that was also his conductor on TV. It also references Liberace's personal appearances during the 1950s. Liberace's feature film debut Sincerely Yours, also produced by Warner Bros., was released around the same time as this cartoon.
The piano piece that Bugs plays is the Minute Waltz (Bugs pronounces "minute" as if to mean tiny) by Chopin, or as Bugs calls him "Choppin'."
When Bugs first sees Mr. Hyde, he says Ralph Kramden's line to him, "You...are a mental case!"
