Dastardly and Muttley in Their Flying Machines Dastardly and Muttley in Their Flying Machines (or simply Dastardly and Muttley in the UK) is a cartoon produced by Hanna-Barbera Productions for CBS. Originally the series was broadcast as a Saturday morning cartoon, airing from September 13, 1969 to January 3, 1970. The show focuses on the efforts of Dick Dastardly and his canine sidekick Muttley to catch Yankee Doodle Pigeon, a carrier pigeon who carries secret messages (hence the name of the show’s theme song "Stop the Pigeon"). The cartoon was a combination of Red Baron-era Snoopy, "Wacky Races" (which featured Dastardly and Muttley in a series of car races), and the film "Those Magnificent Men in Their Flying Machines".
