Ep 12. Marge vs. the Monorail

In The Simpsons season 4 episode 12, titled "Marge vs. the Monorail," the town of Springfield receives a sudden windfall of money and decides to spend it on building a monorail system. After a cunning sales pitch from traveling monorail salesman Lyle Lanley (voiced by the late Phil Hartman), the town unanimously votes to hire him to build Springfield's monorail.

At the same time, Marge Simpson is worried about the town's decision to spend so much money on the monorail, especially since it will be operated by Homer, who has been given no training or experience operating a large transportation system. Her worries quickly come to fruition, as the monorail system proves to be a disaster waiting to happen.

As the monorail system becomes more and more dangerous, Marge becomes determined to stop it before it's too late. She spends the majority of the episode trying to convince the town that the monorail needs to be taken down, while Homer remains blissfully unaware of the danger he's putting the town in.

The episode is notable for its numerous references to pop culture, ranging from jokes about Star Trek conventions to a musical number that parodies The Music Man. As always, the animation and voice acting are top-notch, with the show's signature style and humor on full display.

Overall, "Marge vs. the Monorail" is a classic episode of The Simpsons that showcases the show's unique blend of humor, heart, and pop culture references. It's an essential watch for fans of the show and a great introduction for those who are new to it.
