The sound comes from Family Guy, where the joke is built around a Jackass-style shopping cart stunt taken off a roof. That reference gives it instant context for viewers who recognise the reckless, stunt-show humour, even without knowing the exact episode. Shared as a short soundboard clip, it has found a second life in edits, reaction videos and fail compilations, where the long build-up and crashing payoff do the comic work on their own. Its appeal lasts because the premise is simple, visual and immediately understood.
