The Dangerous Book...

...for Boys.  I just ordered it for my brother-in-law, and scanning the reviews, I just got the thrills.  A six year old treasured it, wearing it out.  ^_^  I love this book.  It has  chapters teaching how to build a treehouse, grow a crystal, tell direction with a watch, handle girls and  learn famous quotes, stories, battles, and phrases that "every boy should know."  Vive masculinity!
