Little did I know that when I picked up The Butter Battle Book at the library I actually picked up “Dr. Seuss Does an Arms Race”! The Yooks and the Zooks butter their bread differently, which leads to weapons, culminating with the creation of the “Big-Boy Boomeroo,” a tiny device that, if dropped, will annihilate the enemy. Could be humorous if not for current events. A few world leaders should read this book. It‘s right at their reading level.
