After a disastrous drop in audience approval, Krusty joins forces with a clown cohort led by Little Debbie Dimples to open a school for the clowning arts. The school is a hit and things are looking cream-pie-in-the-sky for Krusty. But Principal Skinner and town leaders don't think it's funny and sue to revoke the school's license. It's up to Krusty and his students to win Skinner over in an all-kidding-aside trial by amusement.
