Diffendoofer School is an offbeat academy. "Miss Bobble teaches listening, / Miss Wobble teaches smelling, / Miss Fribble teaches laughing, / And Miss Quibble teaches yelling."
Students are taught how to tell a cactus from a cow, tie knots in noodles, saddle a lizard, and use their melons to the utmost--namely, to think, and think fresh.
School principal Mr. Lowe announces the grim news that students must take a standardized test and that if they do poorly, their school "will be torn down, / And you will have to go to school / In dreary Flobbertown," where the school is a totalitarian, conformist institution.
Since Diffendoofers have been encouraged to think, they ace the test and belt out the old school song: "You're gribbulous, you're grobbulous, / Each day we love you more. / You are the school we treasure / And unceasingly adore." The afterword includes Seuss's original sketches and a history of the project.
