.Personally I love the humor in it, but then I've always been a fan of the British style of humor, and I knew pretty much all of the references in the book (like why Ford Prefect is a funny choice, what a zebra crossing is, and so on).
I don't really enjoy Brit humor, and that is the reason I never read it before. However, maybe my great love of Discworld has tempered my dislike for it. I really enjoyed it, even the odd references that I did not understand.
Will someone please kill me if I become a Benny Hill fan?
