this short film is pretty awesome- albeit pretty strange- made in 1988, it combines French cliches of the American west with American cliches of France. I don't know how i stumbled upon in, but I thought I'd provide one more way for others to come across it. If you like to multitask, or if you have a spare half hour, it is a satisfying way to spend that time.
One great drunken bit: Slim chanting "oh la la" while Pierre chants "Yipee kai yai yay" with some good ol' guitar strumming in the background

also, here is a link to the screenplay just for fun
