21 - 10: Once Upon a Time in Springfield

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.
