Nick reminded me yesterday of the excellent Washington Post competition from 1999, asking people to amalgamate literary classics into strange new forms:
Green Eggs and Hamlet — Would you kill him in his bed? Thrust a dagger through his head? I would not, could not, kill the King. I could not do that evil thing. I would not wed this girl, you see. Now get her to a nunnery.
Catch-22 in the Rye — Holden learns that if you’re insane, you’ll probably flunk out of prep school, but if you’re flunking out of prep school, you’re probably not insane.
2001: A Space Iliad — The Hal 9000 computer wages an insane 10-year war against the Greeks after falling victim to the Y2K bug.
The others are very good, too (and they include some not on the list you sent me, Nick): follow the link above to see the rest.
