The Encyclopedia of Immaturity by the Editors of Klutz Press, 2007.

This book is part of the classic children’s hobby and activity series from Klutz Press. It’s a collection of pranks, stunts, and fun things to do. There is too much in this book to describe everything in detail, so I’ll just explain some general themes and highlights.

The stunts and activities are in no particular order, and the book isn’t divided into any special sections. Most of activity or stunts just takes up a page or two of explanation, but some are longer, about three or four pages. None of them are very long.

Some of the activities are classic kids’ activities or pranks, like skipping stones, hanging a spoon from your nose, and Peep jousting (a more modern classic – the book points out that you can do it with regular marshmallows, too, but I like Peeps for the imagery). I remember the one about how to blow a bubble gum bubble from your nose instead of your mouth (found on p. 271) being mentioned in Amber Brown Goes Fourth, when Amber’s new friend, Brandi, teaches her how to do it.

There are also some more difficult tricks to master, like how to do an ollie on a skateboard and how to do a wheelie on a bike. (At least, I consider things like that difficult because I’ve never been able to master them.) I also don’t know how to whistle with my fingers, although the book shows multiple ways to do it.

Some of the pages are designed to be cut out and made into things, like the page that provides a pattern for a paper fortune teller and the page where you cut a square of paper so that it’s possible for a person to go through it.

Some of the activities in the book were also in previous Klutz books, like juggling and how to use trick photography to take pictures that make people look like they’re small enough to pick up. I also remember the backseat rituals for long car trips being part of the Klutz Kids Travel book.

My two favorite sections in the book are the part about how to be a headless person for Halloween and how to sneak around. I never dressed as a headless person as a kid, but I like the idea, and might still do it. I did a lot of sneaking around as a kid because I always loved hide and seek.

There’s quite a variety of activities in this book, including some indoor activities and outdoor activities, and things that can be done on car trips. Some of these activities look kind of gross to me (and still would have when I was a kid because I wasn’t one of the kids who was into gross outs), like how to make fake dog barf, but there’s such a wide selection of activities, I’d say that there’s plenty here for anybody to find fun things to do!

The book is available to borrow and read for free online through Internet Archive (multiple copies), along with the sequel to the book, The Encyclopedia of Immaturity, Volume 2.
