"The Human Centipede The Musical"
Though I can barely stomach knowing the basic concept for those films, much less ever watching them, even I can see the potential for some amazing choreography here.
I've also spent too much mental energy working out the logic of a Star Trek musical in which, as is often the case, music = emotion, so the human characters would sing and/or dance everything while some Vulcans would speak all their lines and look on at all the human/musical theatre silliness with disdain. Half-human Spock would speak in rhyming couplets without ever realising or admitting he was doing so, with some climactic all-out singing moment. It would be terrible/great!
