In the landmark 450th episode of THE SIMPSONS, Krusty is approached by two network executives who want to bring on female co-star Princess Penelope to increase the show's female demographic. The onstage and behind-the-scenes rapport between Krusty and Princess Penelope grows, and before long, Krusty asks for his co-star's hand in marriage. Meanwhile, when Mr. Burns puts a stop to the free donuts at the plant to cut costs, Homer, Lenny and Carl decide to meet with a headhunter who specializes in nuclear workers and opens their eyes to opportunities free of draconian donut-cutting measures.

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.
