Great Book! Very Funny!
The complete collection of Adams' stories about Ford Prefect, Arthur Dent, Zaphod Beeblebrox, and Ms. Trillian. If you like humor, spaceships, or British people, read them. Did I mention there is a robot who wants to kill himself? The first page is probably the funniest thing I've ever read.
I will admit, the first three books are by far the funniest, but every story is well worth the read.
