The sound comes from Fall Out Fall In, a Donald Duck cartoon released on 23 April 1943, in which Donald's army camp routine provides the setting for a bugler's brief snore. Like many short cartoon effects from that era, it was later catalogued as a stock snoring effect and circulated through sound libraries, which helped it reach meme and video editors long after its first broadcast. Its appeal today is its brevity and clarity: in under half a second it signals sleep without needing any dialogue or context, so it still works as a quick gag in short-form edits.
