This long-running animated comedy focuses on the eponymous family in the town of Springfield in an unnamed U.S. state. The head of the Simpson family, Homer, is not a typical family man. A nuclear-plant employee, he does his best to lead his family but often finds that they are leading him. The family includes loving, blue-haired matriarch Marge, troublemaking son Bart, overachieving daughter Lisa and baby Maggie. Other Springfield residents include the family's religious neighbor, Ned Flanders, family physician Dr. Hibbert, Moe the bartender and police chief Clancy Wiggum.

Professor Frink uses an astrology machine to ease Bart and Lisa's bickering, giving them a sneak peek at their final days of high school.

When Bart and Lisa unearth Marge's diploma from Springfield University, Marge reminisces about her college days, when she dated a pretentious professor and Homer became a music star.

Disappointed with Yale, Mr. Burns decides to start his own for-profit university and hires Homer as a professor.

Grampa gets a hearing aid and finally hears what everyone has been saying about him; Principal Skinner discovers that his mother has kept a secret from him.
