Double or Mutton is a 1955 Warner Bros. Looney Tunes cartoon directed by Chuck Jones. The short was released on July 23, 1955, and is the third cartoon featuring Ralph Wolf and Sam Sheepdog. Mel Blanc provided for the voices of all the characters in this cartoon; however, like all Ralph Wolf and Sam Sheepdog shorts, this short is mostly composed of visual gags. The title is a play on the gambling wager double or nothing. This is also the first short where it is clearly established that Sam and Ralph are coworkers, as well as the first short where their names are consistent.
