Dastardly and Muttley in Their Flying Machines was a Saturday morning cartoon produced by Hanna-Barbera Productions for CBS from September 13, 1969 to September 5, 1971. The show's working title was Stop the Pigeon, and the show's theme song (derived from "Tiger Rag" and sung by Dick Dastardly himself) repeats the phrase so often that it is easy for that to be mistaken for the show's actual title. Under the working title, Dick and Muttley were not part of the cast; a chubby, heavy-jowled Red Baron-esque pilot and a dachshund in flying goggles were the central figures. It appeared that those figures were not going anywhere insofar as development, so the characters of Dastardly and Muttley were plucked from Hanna-Barbera's earlier Wacky Races for the series.
