The "New York Times" Guide to Essential Knowledge: A Desk Reference for the Curious Mind Hardcover – 30 Oct. 2007

A good way to irritate and intrigue (in equal measures!) your work colleagues. I keep it at work for when our connection to Google is too slow.

Essential reading for people who are interested in the world and life in general. Is full of interesting facts and stats. Much more fun than a search on Google.
