When I was a lad in college, we had an assignment that went over very well. We were to take a few sentences from one author and rewrite them in the style of another. It taught us something about the nature of composition or some such. Here's an example, and I beg the denizens of this fine community to contribute.

"Look," he said, "pay attention. This is important. I need you to go over these mountains, see, and do something about this dragon. He's a dragon for fuck's sake. Been tormenting the land about the mountain for years; time he cashed his check. Are you willing? Have you got the nerves?"
Bilbo's first sane thought was, what's in it for me?
