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.

Fearing that she will end up like Marge, Lisa pledges to focus solely on her academics and not get distracted by other things; Bart puts Nelson in his place and unintentionally earns the title of school bully.

Mr. Burns becomes distraught at the town's apathetic reaction to the announcement that he has only weeks to live; Bart secretly takes Burns into the family's home.

After Bart nurses an injured bird back to health, Homer enters it in a race.

When the rest of the family seems to lack Christmas spirit, Marge contacts Martha Clause (guest voice Martha Stewart).
