Terry Pratchett. Funniest books ever.
Okay, other people were able to explain what I wasn't able to put into words.
Basically, I like a lot of authors very very much, but if I had to choose only one author's books to read for the rest of my life ("you're stuck on a desert island, you've got plenty of food, water, and can comfortably sleep on the plush ground under sheltering trees. The only other thing on the island is a box of books that washed up on shore. All the books are by the same author, what author do you want it to be?")
