The phrase comes from Dastardly and Muttley in Their Flying Machines, the late 1960s Hanna-Barbera cartoon in which Dick Dastardly and his dog Muttley repeatedly try to stop Yankee Doodle Pigeon from delivering messages. Shouted in almost every episode, it became the show's running joke and a shorthand for a villain whose elaborate schemes always fail. Decades later, cartoon fans and meme editors revived the line for chase clips and reaction videos, keeping it alive as a quick signal for comic desperation.
