The Butter Battle Book by Dr. Seuss

The story is a satirical tale about two groups, the Yooks and the Zooks, who are embroiled in a long-standing conflict over their differing customs of buttering bread. The Yooks butter their bread side up, while the Zooks butter theirs side down, leading to an escalating arms race as each side develops increasingly elaborate weapons to outdo the other. Through whimsical rhymes and illustrations, the narrative explores themes of rivalry, the absurdity of conflict, and the potential consequences of an arms race, ultimately leaving the resolution open-ended to highlight the futility of such disputes.
