When we last saw our heroes, George and Harold, they were under arrest and headed for prison. Then Harold foolishly uttered the fateful words, 'What could be worse than going to jail for the rest of our lives?' and changed the course of human history. In this ninth epic novel, Dav Pilkey takes readers back in time to the carefree days of kindergarten, when the worst thing George and Harold had to face was NOT evil mad scientists or alien cafeteria ladies but a sixth-grade bully named Kipper Krupp, the nephew of their clueless school principal.
