Encyclopedia of Immaturity

All who are given the Encyclopedia of Immaturity must place their right hand on it and repeat: "I promise to never, ever grow up. I vow to never stop hanging spoons from my nose, and to always do my best to annoy my siblings." More than 300 entries are each painstakingly explained and illuminated with full color photographs, illustrations and diagrams. An award winner, believe it or not!  Encyclopedia of Immaturity from Klutz #135424.  Ages 8 to Teen (though we've had quite a few folks buy it for adults!)
