Meanwhile, Professor Poopypants sees an ad to teach at the school and applies for the job, thinking children to be kind and sweet-hearted, but they spend days laughing at his silly name. The professor only gets them interested by building a robot that makes gerbils jog along with them but it is short-lived. Some time later, Ms. Ribble reads The Pied Piper of Hamelin, which inspires George and Harold to make a comic about the Professor trying to take over the world, which destroys the last of Professor Poopypants' sanity.
