Pee-wee's Playhouse was a children's television series created by Paul Reubens that mixed live action, puppets and cartoon segments, and its exaggerated sound effects became part of its playful world. The fish laugh fits that style, sounding deliberately absurd rather than realistic, and it later found a second life on soundboards and in short-form video, where creators reuse it as a quick reaction sound. Its appeal has lasted because the laugh is instantly recognisable as cartoon silliness, even for viewers who never watched the original show.
