Book of Secrets
Published in the form of a leather-bound hymnal or sacred text, The Book of Secrets is filled with short, little-known facts an anecdotes on science, sex, politics, history, and other subjects. The first entry in the book shares 10 secrets for "attracting beautiful women," followed by the "secret German link between Elvis, Frank Sinatra, and The Beatles."
I enjoyed the "secret tricks of the trade" section. Here's a trick for an actor: "A wise old actor once told Michael Caine, 'don't act like a drunk man. Act like a drunk man trying to be sober.'"
Some of the entries can hardly be considered secrets, but they're entertaining nonetheless.
