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...

            I want to read all the Captain Underpants because I think it is funny. I want to read them but don't know where to get them so please tell me how. I also want to know where i can watch the movie without going to a movie theater. I can only watch movies at home. Please tell me and please follow me.
