This was an idea from a while back.  Basically a pisstake of more or less all musicals and operas ever.  The idea is that the characters have been pared back to their most basic form.  The main girl is the Soprano, the evil dude is the Tenor, and so on and so forth.  It could be just be a really condensed simple plot, where everyone just states their intention outright and then does it, for example, the Tenor is standing next to the Soprano, says he loves her and he is going to take her away and then proceeds to try and take her off stage.  The main dude (is it Alto?  Hell, I dunno the names), says he will slay the Tenor, and then does that.  And the Tenor says something like "How could I not have seen this coming?"
