The sound comes from Get Rich Quick, a Goofy short released on August 31, 1951, during Disney's classic theatrical cartoon era. In that period animators relied on exaggerated vocal and effects work to sell gags without modern sound design, and a squeaky smooch could carry a joke on its own. The clip later circulated on soundboards detached from the short, where its old-fashioned cartoon timing made it easy to reuse. It remains popular because newer kiss effects often sound realistic, while this one reads instantly as comedy.
