Audio Books?

Can anyone recommend any decent literature in audio format? I found recently I enjoyed listening to The Hitchhiker's Guide to the Galaxy (the radio play) while programming, but I wouldn't want it to get stale after the 100th time, so I'd like some suggestions for alternatives. Something humourous would be preferred.

How can you listen to something complicated while doing something complicated :X?

Batman - Knightfall.

BBC radio production, like H2G2 was so good voice acting and production. Its only 2/3 hours long though.

What about Star Wars?
