George and Harold accidentally create a monster in the fifth book in this #1 New York Times bestselling series by Dav Pilkey, the author and illustrator of Dog Man! George and Harold are always good at using their imaginations, and that drives their mean homeroom teacher, Ms. Ribble, crazy! But this time, they've come up with much more than a silly prank... With her horrendous hairdo and two rabid robots, Wedgie Woman is well on her way to world domination, and only the Waistband Warrior can stop her!
