As this book says in the introduction, growing up is not something you should rush into.
So, if you are not ready for the serious stuff of life yet, you may be interested in having a nosey here.
Just a few of the important things included are: how to booby trap a drink , how to shinny up a tree, frozen underpants, the one-person piggy back , great cell phone shots and so on.
The Encyclopedia of Immaturity is a chunky (nearly 200 pages) book of activities, pranks and info that you can’t miss if you enjoy the ridiculous.
