Merrie Melodies - Golden Yeggs (1950)

Golden Yeggs is a 1950 Warner Bros. Merrie Melodies short directed by Friz Freleng. The cartoon was released on August 5, 1950, and stars Daffy Duck and Porky Pig. A forerunner of the Rocky and Mugsy characters appear, with Rocky already in his present-day form.

The story was written by Tedd Pierce and animated by Arthur Davis, Gerry Chiniquy, Ken Champin, Virgil Ross and Emery Hawkins. Paul Julian painted the backgrounds and Hawley Pratt designed the layouts. Mel Blanc provided the voices (except for a goose, voiced by Stan Freberg) and Carl W. Stalling the music.
"Yegg" is a slang term for a burglar or safecracker. The same play-on-words was used in the title of the 1947 Bugs Bunny cartoon, Easter Yeggs. This cartoon also appeared in the magazine Time Inc. (owned by Time Warner), which would later spun off on June 6, 2014.

Alternative ending:
When this cartoon was used in The Looney Looney Looney Bugs Bunny Movie, a new ending was used. Instead of Daffy fainting, Bugs Bunny, alias Elegant Mess (a parody of Eliot Ness), arrives with the police to bust Rocky and his gang. Daffy is exhausted by carrying out Rocky's orders. Naturally, Rocky and his gang are arrested. Daffy is taken to a hospital on a stretcher. Bugs asks Daffy if he needs anything and Daffy requests a proctologist, immediately.
