This is one of my favorite books to give as a gift to a child. Why? Well, why is it dangerous to do math with a spider? Lift the flap and find out.... If you add 4 and 4, you get ate! Then, push the button, and hear the laugh! It's so fun. Joke after joke on page after page, and you can just keep pushing that button! It's a joke party! Great for reluctant readers.
