The cash register sound is a classic stock effect rather than a clip from one specific film or show, and it has long been used to signal a sale in comedy, cartoons, and advertising. Its bell and drawer became shorthand for money because audiences recognise the sound of a real till instantly, even without seeing one. Online, creators reuse it in short videos, streams, and memes whenever a joke involves spending, winning, or charging a ridiculous price. That simple money association keeps it useful across formats, from shopping content to gaming clips.
