This three-book boxed set captures the classic Klutz spirit: funny, and ever-so-slightly subversive, with ideas so odd you wonder no one ever thought of them before. The Encyclopedia of Immaturity: short attention-span edition: the best and most essential life skills from our best-selling two-set of encyclopedias. -- The Klutz Book of Inventions: The most mind-blowing contraptions from our immature take on engineering and product design. -- The Greatest Facts in the History of Facts: An all-new book of mind-boggling realities, guaranteed to provide a lifetime of conversation starters. It's the truth's greatest hits, according to us.

Includes material previously published in The Encyclopedia of Immaturity (volumes 1 & 2) and The Klutz Book of Inventions. --Container.
