SpongeBob SquarePants is a long-running Nickelodeon animated series set in the underwater town of Bikini Bottom, where nautical sounds like foghorns fit the seafaring theme. Clips of its exaggerated sound effects have circulated for years on meme pages, soundboards and short-form video, where editors reuse them out of context for comedy. The foghorn version endures because it is instantly recognisable, easy to drop into a reveal and flexible enough for both sincere drama and parody.
