Catalog log
Broadcast listing — not a TV Flash recap.
Homer is upset when he realizes that Marge brought him and the family to a boring Harvest Fest instead of his much-anticipated day of debauchery at October Fest. Attempting to leave, Homer accidentally drags the family into a puzzling cornfield maze. When the whole family manages to escape except for Homer, they send out Santa's Little Helper, who sniffs out Homer and rescues him. Santa's Little Helper becomes a local hero and the Simpsons decide to enroll him in Police Dog Academy, where he's teamed with a grizzled veteran cop named Lou and they become a crime-busting duo. Bart's excitement quickly dissipates when a jaded Santa's Little Helper bites him, and the Simpsons send the dog away to live with Chief Wiggum. To appease Bart's depression after the loss of his dog, Marge agrees to buy him a huge pet snake. But when the snake causes a life-threatening situation at Bart and Lisa's school, Santa's Little Helper gets a chance to redeem himself.

Why this series still plays
Watch it as a living joke encyclopedia, not a series you owe from pilot to present. The early years still teach how American satire learned to reset weekly; the later catalog is optional weather. You already speak Springfield. This is how the grammar got written.
The first image is a couch, and then it is not. The Simpsons treats the opening gag as a weekly contract: we will reset the living room, and we will still find a new joke about the country that owns it. Fox put a yellow family on Sunday nights in 1989 after the Tracey Ullman shorts, and the half-hour that followed did not merely popularize adult animation. It installed a shared vocabulary. People who stopped watching still speak Springfield.
