When we published The Encyclopedia of Immaturity in 2007, we knew it would make a great gift for someone's nephew. And, sure enough, people gave it to their nephews -- but also to their grandparents, brothers-in-law and accountants. Soon we were flooded with letters, e-mails and calls sharing one common theme -- ''More! More! More!'' So here's a second helping of skills, activities, and secret knowledge -- suitable only for those whose maturity stopped developing around the age of 12. In addition to thought-provoking topics like What We Talk About When We Talk About Wedgies, the book includes detailed directions for how to: fake a cold, slide down a banister, balance a ping pong ball on your nose, send a toiletgram, throw a sloshie, and more. It's all new and all hopelessly goofy. You can imagine our delight as we looked over the sales figures for the first volume of this encyclopedia. For years we've felt like the only kids at the grown-up table. Now it turns out the world is populated by a lot more people who are lot less mature than they look. Well, duh!
