Book excerpt: Do you have a big sister? Do you know how to drive her crazy? It's easy, really easy. Take it from me, Bradley Harris Pinkerton. Does your sister hog the bathroom? Does she spend hours on the phone with her friends? Then this book is for you! All you need is a rubber snake, some bubble gum, and a little bit of sneakiness. Oh, and a really good hiding place. Note: Do not let your sister read this book!
