Name That Trauma :: Reader Diana G. on a Taxidermist on Trial

This one has puzzled experts for decades.

When I was a kid, I saw a cartoon about a taxidermist having a nightmare. He was put on trial and sang to a jury of animals. The taxidermist sang, "I ain't gonna stuff no more, no more, ain't gonna stuff no more."

And the all-animal jury replied,"He just says so, how do WE know he ain't gonna stuff no more?"

I suspect it was a Harvey Toon, since that's the package our local after-school show ran more often than not. But for decades I've been trying to see this cartoon about stuffed animals putting the man who stuffed them on trial.

Any help would be appreciated!
