Here's the proof:
So how about an impromptu review from The Professor:
This book is called the Dangerous Book for Boys and I really think it is interesting. No wait, I mean... I think it is really interesting. It has all the supplies a boy should have. It mostly tells you how to do things like skin a rabbit and how to make some cool paper airplanes. It tells you about the time period of the dinosaurs and it also tells you how to play marbles and about famous battles like Julius Caesar's invasion of Britain.
My favorite part was that it tells you how to make a bow and arrow. Some of the instructions are kind of hard to understand but I think I might be able to manage it with the help of a grownup. It also tells you how to make a simple go cart. I'm not sure where to get the four wheels, but I would like to try it someday.
It talks about girls too. It tells you that when they aren't able to lift something, don't taunt them. Offer to help. If you can lift it, ask where she wants it to be put and if you can't, sit down and just talk to her. I don't think I will need to read that chapter until I am 12 or something.
I think that boys from 9 to maybe 20 would like this book but my dad likes this book and he is older than that!
