Miles Murphy and Niles Sparks are great at being terrible. Nearly every day the fearsome pranking duo turns Yawnee Valley Science and Letters Academy upside down with their stunts. The Big Chirp. The Cafeteria Calamity. Their pranks bring joy to their classmates and embarrassment to their nemesis: blowhard Principal Barkin. But one day—school picture day, to be precise—a scheme goes too far, and Principal Barkin ends up fired. His replacement: Principal Barkin Senior, the principal’s no-nonsense father. The new principal runs the school with an iron fist, out to destroy all signs of fun. No group work. No Pajama Day. And definitely no pranking. “Fast-paced and laugh-aloud funny, the book will appeal to a wide range of readers. Frequent, humorous graphics will attract fans of visual storytelling and also make the book more accessible to reluctant readers. Quirky writing and colorful dialogue make the book an excellent read-aloud.” - School Library Journal
