Douglas Adams is one of my favorite authors. @ assassin: you should definitely read the first 3 Hitchhiker books, a lot of things are revealed. Oh, and I'd skip the DaVinci Code, way overrated IMO. I read half and then tossed it.

The fourth and fifth Hitchhiker books are so-so. You may want to read the Dirk Gently novels instead, I enjoyed those too. Douglas Adams also wrote a book with Neil Gaiman, but that one is pretty weird. Anyway, I think I'll spam some Douglas Adams quotes now:

In the beginning the Universe was created. This has made a lot of people very angry and been widely regarded as a bad move.

A common mistake that people make when trying to design something completely foolproof is to underestimate the ingenuity of complete fools.

Arthur hoped and prayed that there wasn't an afterlife. Then he realised there was a contradiction there and merely hoped that there wasn't an afterlife.

He felt that his whole life was some kind of dream and he sometimes wondered whose it was and whether they were enjoying it.

It is a well-known fact that those people who must want to rule people are, ipso facto, those least suited to do it... anyone who is capable of getting themselves made President should on no account be allowed to do the job.

Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the drug store, but that's just peanuts to space.

The Guide is definitive. Reality is frequently inaccurate.
