Surprising things from the retro cartoon channel, subsection "you really couldn't make that today": think it was a Harvey Studios, one of their 'tortoise and the hare' shorts from the '50s. Wherein after losing to the turtle again, the hare cartoonishly but unambiguously commits suicide. Pulls a gun out of hammerspace, shoots himself, angel floats off, iris out.
Boy howdy. Yeah, you couldn't get away with that today.
