Muttley's wheezing, snickering laugh from Wacky Races, the classic Hanna-Barbera cartoon, used in memes and edits for sneaky or mischievous moments.
This is Muttley's signature laugh, a high-pitched, wheezy snicker that starts quietly and builds into a raspy, breathless chuckle, as if he is barely holding back a joke at someone else's expense. The sound is instantly recognisable from his role as Dick Dastardly's snickering sidekick, and it carries a sly, scheming tone that makes any scene feel cheeky rather than outright mean. Played over a clip, it signals that something mischievous has just happened or is about to go wrong, turning a small prank, a failed plan or a sly glance into a punchline that viewers immediately understand without any dialogue.
Muttley first appeared in the Hanna-Barbera cartoon Wacky Races in 1968 as the wheezing, snickering dog sidekick to Dick Dastardly, and his laugh became one of the show's most recognisable running gags. The character returned in later Hanna-Barbera series, keeping the same mischievous snicker, and clips of the laugh spread through cartoon compilations, reaction videos and meme edits. Like the Woody Woodpecker laugh, it works because listeners recognise it instantly, even without seeing the character, and it still signals sly amusement in short videos today.
