Started by Dr. Seuss, finished by Jack Prelutsky, and illustrated by Lane Smith, Hooray for Diffendoofer Day! is a joyous ode to individuality starring unsinkable teacher Miss Bonkers and the quirky Diffendoofer School (which must prove it has taught its students how to think—or have them sent to dreary Flobbertown). Included is an introduction by Dr. Seuss's longtime editor explaining how the book came to be and reproductions of Dr. Seuss's original pencil sketches and hand-printed notes for the book—a true find for all Seuss collectors! Jack Prelutsky and Lane Smith pay homage to the Good Doctor in their own distinctive ways, the result of which is the union of three one-of-a-kind voices in a brand-new, completely original book that is greater than the sum of its parts. For all of us who will never forget our school days and that special teacher, here is a book to give and to get.

The students of Diffendoofer School celebrate their unusual teachers and curriculum, including Miss Fribble who teaches laughing, Miss Bonkers who teaches frogs to dance, and Mr. Katz who builds robotic rats.
