Do you know Colonel Sander's secret recipe?
Did you know there's a secret daily flight from the United States to Cuba?
Did you know that there's an abandoned underground movie theater in France?

Secrets like these are finally revealed in the very top-secret and very tiny Book of Secrets ($6). Inside you can discover hundreds of covert pop-cultural and historical curiosities, government cover-ups, marketing tricks and practical secrets. I don't think it contains the clues to discovering any national treasures, but it would be a funny little coffee table book next to the big books. (via Michael Kiely)
