Mutley is the snickering dog sidekick to Dick Dastardly in the Hanna-Barbera cartoon Wacky Races, first broadcast in 1968, and later in Dastardly and Muttley in Their Flying Machines. His wheezy laugh became one of the show's most recognisable running gags, signalling that a cheating scheme was underway or had just gone wrong. Decades later, short cartoon laughs like this one circulate widely in meme edits, reaction videos and chat audios, where a single familiar chuckle can carry the whole joke without any dialogue.
