This clip comes from Window Cleaners, a Donald Duck cartoon released on 20 September 1940, in which Donald and Pluto work as window cleaners and encounter a bee. The short buzz was later preserved in Hollywood Edge sound libraries as a fly sound, which helped it circulate beyond the cartoon itself. Today creators reuse it as a tiny, instantly recognisable cartoon insect noise, valued because its vintage Disney origin gives a familiar, playful feel that modern buzz recordings rarely match.
