Speaking of satire, how about this idea:
A race of advanced, space faring, bicycle riding humanoids create a race of robotic "Carlons" to do their bidding for them. The Carlons (through an accident of artificial intelligence) become self-aware and begin to take revenge on their former masters by polluting their land, sea and air. The carlons massacre the humanoids, until a small group of survivors, led by the Battlecycle Galactica, escape and form a tenuous civilization of whiskey-fueled whiners. "Why did we make all those Carlons?" they ask themselves, and "What does it all mean, anyways?"
