Take a few of my geek points away

[servermonkey]

I am only now getting around to The Colour of Magic and have never read a single page of the Discworld books.

I have owned The Fifth Elephant for a while now, but really want to begin at the beginning.

Or does it not matter as much with some of the story arcs?

I really enjoyed Good Omens a long while back and have been meaning to pick that one up again sometime.
