Hooray for Diffendoofer Day!A hilarious story about all the pupils and teachers at Diffendoofer School, written with all of Dr. Seusss classic trademark wit. Diffendoofer School isnt your average school. With classes on yelling and smelling and teachers bouncing on trampolines, this brilliant tale highlights the importance of individuality and thinking for yourself! This splendid school based story was the last storyline developed by Dr. Seuss shortly before his death in 1991.
