This sound comes from the cartoon animal-effect tradition associated with Warner Bros., where exaggerated goat and sheep bleats were used to sell a quick farmyard gag without dialogue. The short clip has circulated on user soundboards as a ready-made animal reaction, rather than as a line from a single famous scene, and its appeal is its instant recognition: listeners hear farm animals and expect silliness. That simplicity keeps it useful for memes, streams and edits that need a fast, family-friendly animal joke.
