The effect is credited to Disney sound artist Jimmy MacDonald and was created for the Donald Duck short Chef Donald, released on 5 December 1941. MacDonald built many of Disney's early cartoon effects from everyday objects and vocal tricks, and short zips like this became a staple of the era's animation language. As classic cartoons were reused in compilations, edits and meme videos, the keen zip out survived as a ready-made shorthand for instant, comedic speed, still recognisable decades after its first theatrical use.
