The cash register sound is a classic stock effect rather than a clip from one show, built around the bell and drawer of a mechanical till. It became a universal audio shorthand in cartoons, comedy sketches, and adverts, where a single ring could signal that money had been earned or spent without any explanation. Online, editors adopted the same two-second cue for haul videos, sales announcements, and money memes, because viewers recognise it instantly across languages, including in Spanish-language clips where it is shared as caja registradora.
