Mr. Plow/References

Cultural References

 * Homer goes to the advertising firm of McMahon & Tate, which was the name of the advertising firm on Bewitched.
 * The avant-garde Mr. Plow commercial which not even Homer was sure whether or not was promoting his business was based on a Russian perfume commercial the writers saw. The producers parodied the commercial without permission, however, due to troubles with international relations between the United States and Russia, as of 2009 the producers of the perfume commercial still have been unsuccessful at seeking litigation against The Simpsons TV show.
 * The snowmen at the end melted the same way as the main villains did at the end of Raiders of the Lost Ark.

Trivia

 * When Homer makes the phony call to Barney claiming he has a $10,000 bill, Barney tests him by asking which American president appears on the $10,000 bill, Homer responds "All of them! They are having a party. Jimmy Carter is passed out on the couch!" Had Barney had better knowledge of American law or money, he would have recognized he was being set up. It is illegal in the United States to engrave American money with images of living people. Furthermore, the ten thousand dollar bill does not feature a U.S. President, but rather Supreme Court Justice Salmon Chase.
 * Originally, the Plow King's identity was supposed to be Lenny, but it was changed to Barney due to Lenny not fitting in with the story.
 * Troy McClure mentions that the viewer may remember him from The Erotic Adventures of Hercules, the film Marge and Homer were watching in the episode Kamp Krusty.

Goofs

 * When Homer is about to drive up the mountain to save Barney and Marge is begging him not to, Maggie’s coat is blue. But when the family is watching the mountain goat fall down the mountain, her coat is orange.
 * When The Simpsons are driving to save Barney, they come across a bridge. At first, the bridge is covered in snow, the angle then changes and the snow disappears.
