Mr. Plow

"Mr. Plow" is the 9th episode of The Simpsons' fourth season.

Synopsis
It is snowing badly in Springfield, so Marge calls Homer at Moe's Tavern and tells him to come home right away. Homer drives through a snowstorm and both cars are destroyed as a result. He lies to an insurance claims adjuster about his whereabouts before the accident in order to cover the fact that he was drunk at the time.

Homer goes to a car show to get a new car, where a salesman talks him into getting a snowplow because he can pay the higher debt by using it to plow snow off the roads. Homer starts his snow plow business as "Mr. Plow" with the help of a late-night ad and becomes a success, even being given a key to the city.

Barney asks how he can be a success so Homer says to go out and be the best Barney he could be. The next day Barney has bought a bigger plow, and with Linda Ronstadt's help, creates an ad as "The Plow King", which steals all of Homer's customers. Mayor Quimby takes back the key from Homer to give it to Barney. To get revenge Homer tricks Barney into going on a fake plow job.

Without Barney around Homer begins to plow driveways again, but the news reports there has been an avalanche on the mountain that Homer sent Barney to. Homer, feeling guilty, sets out to rescue him, and in the end they agree to become partners. Their claim that not even God could stop them brings about a response from God - the melting of the snow. Homer's plow is repossessed at the end of the episode.
