This short, silent, animated film was absolutely hilarious. It has an adult theme (a man is frustrated with desire and can neither satisfy his urges nor repress them) but due to its creativity, I don’t think anyone could watch this and not find it funny.
It is apparently hard to find. I saw it at a museum showing. I have heard it is also in a compilation DVD that won a Cannes Film Festival award a few years ago called The Good Old Naughty Days.
