The Lazy GM

From Gamegrene.com:

I have to say I'm a lazy GM. I don't have the time or the energy to prepare a vast amount of background, labyrinthine plots, or hundreds of stats for monsters. So I spend an awful lot of time winging it during a game. My plots may be complex, and the background detailed, but this has little to do with the preparation I put in; mostly they are player lead adventures, and so I rely upon them for a lot of the inspiration and development of the game.
