The sound comes from The Simpsons, the long-running animated sitcom built around Homer Simpson and his family in Springfield. Homer's clumsy falls, screams and hard landings have been a recurring slapstick gag throughout the show, making this kind of tumble instantly recognisable even without any picture. Short clips of those moments have circulated widely in meme edits, reaction videos and soundboards, where the fall alone can carry the joke. It remains popular because the cartoon exaggeration is universal, funny across languages and easy to drop into almost any fail.
