Perry Homer is bad news, just like the rest of his troublemaking family. Perry thinks he could be good. His favorite teacher, Miss Penelope, recommended him for a scholarship at the prestigious Ithaca School, and it's his chance to change things. He just has to get home from Lindsborg and show up for the interview. Still, that's easier said than done. After the Homers get kicked off their plane, Perry comes up with one last scheme to keep them pointed toward home.
