Pluto first appeared as Mickey Mouse's loyal dog in the early 1930s, and by 1941 he had become an expressive star in his own right in Disney shorts. A Gentleman's Gentleman, released on 28 March 1941, gives Pluto a moment of comic shame, and this brief whimper captures that expression in sound alone. Shared later through sound effect libraries and online soundboards, the clip became a handy shorthand for guilt, fear and disappointment. Its age and cartoon clarity help it remain instantly readable, even to viewers who have never seen the original short.
