52:5 Life, the Universe, and Everything, by Douglas adams.

Can you believe it?! I've read 3 books in this series in three days! Anyways, we find some interesting things. For example, we find out that the Ultimate question and the ultimate answer cannot be known in the same Universe. They are each Mutually exclusive. Frankly, I wouldn't be surprised if I finished the 4th book in the series tomorrow. Dang, I'm reading this book quickly.
