A Very Short War: Steve Barlow and Steve Skidmore, Star Bores, (USA and UK, Element Chidren's Books, 1999).
A spoof of Star Wars -- pretty bad but draws attention to the meaningless nature of two sides:
Bureau for the Advancement of Desruction, Depravity and Incredibly Evil Schemes (BADDIES)
Grand Order of Democratic Independent Emancipated Societies (GOODIES)
And I can't help loving a book where Princess Liar goes off with Choccibiicci, the hairy Cookie and leaves Han Zup and Puke Moonwalker to drink themselves to death in a bar.
