Professor Pippy P. Poopypants may be the greatest scientific genius the world has ever known. Unfortunately, he has such a silly name that nobody takes him seriously! Needless to say, George and Harold poo-poo Poopypants' pride -- practically pulverizing it -- and Poopypants is preparing to pounce! This looks like a job for Captain Underpants...

                This book is hilarious with all funny names that I have never heard before. Professor Pippy P . Poopypants was laughed at for his funny name. So he created the name change-O-chart 2000 with silly names to change everyone's name on the planet. But he never thought of changing his own silly name.
