This is one of my favorite book to ever be made. Though I'm not really suprized that I'm the only one on this site to say anything about it. I also own this book, it was one of the first books that I've ever owned. Now I've got over like 100 books but ever once in a while I'll go and find this book and read it again. There is a story behind me and this book, but I'll save that for another day.
