Product Description
George and Harold, and their doubles, Yesterday George and Yesterday Harold, have a good thing going. Two of them go to school, while the other two hide in the tree house playing video games — then they switch! But when gym teacher Mr. Meaner uses mind-control to create obedient, perfect robot children, the future of humanity is in their hands!
