This descending boing was created by Disney sound designer Jimmy MacDonald for the Mickey Mouse cartoon Canine Caddy, released in 1941, where it helped give Pluto's antics a springy, musical quality. It later entered the Hollywood Edge sound library as a wooden twang and musical boing, which made it easy for editors to reuse in cartoons, comedies and online videos. Its short length and clear downward slide still make it an instantly readable gag for clumsy falls and failed stunts.
