Uncle Shelby's Abz Book by Shel Silverstein

A darkly comic parody of a traditional alphabet primer that pairs silly, often subversive definitions and cartoons with each letter, offering absurd, mischievous instructions and gross-out jokes that deliberately undermine didactic children’s-book morals; the result is a satirical, irreverent take on learning the ABCs that uses humor and cartoonish illustrations to lampoon authority and conventional instruction.
