Homer vs. the Eighteenth Amendment

After Bart Simpson accidentally gets drunk at a St. Patrick's Day parade, a prohibitionist movement emerges in Springfield. After it is discovered that a ban on alcohol has been in effect but gone unnoticed for two centuries, Mayor Quimby, not wanting to alienate voters during an election year, agrees to enforce the law. However, the mob continues to supply the town with alcohol through bribery of local law enforcers, allowing Moe Szyslak to reopen his bar disguised as a pet shop. There, a group of staunch prohibitionists discover an intoxicated Chief Wiggum and demand his removal. Wiggum is replaced by U.S. Treasury officer Rex Banner, who blockades the city entrance and buries all of the alcohol in a mass grave at the city dump.

Homer Simpson concocts a plan to continue supplying Springfield with alcohol: he and Bart reclaim the beer disposed of at the dump, pour it into the finger holes of bowling balls and, through a intricate network of pipes set up under Barney's Bowl-A-Rama, bowls them straight to Moe's. Upon discovering their scheme, Marge is actually impressed Homer was able to devise it and encourages him to continue, although Lisa questions whether Homer should be breaking the law whether or not it may be arcane or unpopular. The media realizes someone is allowing Springfield's underground alcohol trade to flourish, and they dub the still-unknown Homer "The Beer Baron". Banner's unsuccessful policing of Springfield's prohibition law and investigation into the Beer Baron's identity sees him miss or overlook blatant clues that the law is being ignored by the town and that Homer is the Beer Baron (which is effectively an open secret to the rest of the town).

When the beer supply runs out, Homer distills his own homemade liquor but eventually his stills explode, leading Homer to cease bootlegging (after one sets him on fire). A desperate ex-Chief Wiggum attempts to mug Homer with the remains of his gun, leading Homer to pity Wiggum and allowing him to turn him over to the police. After confessing to his crimes in public, Homer, originally believing he would be let off with a light punishment, faces expulsion from the town (and likely death) by catapult, showing how anachronistic the law really was. Marge pleads with the town not to punish Homer as the prohibition law and its punishment make no sense and are robbing people of their freedoms, especially to drink. When Banner steps up to lecture the town on the reasons why the law must be upheld, Wiggum has him catapulted. The town clerk then finds out that the prohibition law was actually repealed a year after it was enacted and Homer is released. Mayor Quimby asks Homer if he can re-supply the town with alcohol, but Homer tells him that he is retired. Within five minutes, Fat Tony and the mob have the town re-stocked and Springfield salutes alcohol's qualities, with Homer proclaiming his undying love of alcohol by saying, "To alcohol! The cause of, and solution to, all of life's problems."

The main plot of the episode is based on the Eighteenth Amendment to the United States Constitution, in which alcohol was banned in the United States.^[3] As The Simpsons has many episodes that have stories and jokes related to alcohol, the writers thought it was strange that they had never done an episode related to Prohibition, and that the idea seemed "perfect."^[3] The episode features a vast amount of Irish stereotyping at the St. Patrick's Day celebration. This was a reference to when Conan O'Brien was a writer for the show and was of Irish descent, and his use of Irish stereotypes.^[3] Various writers were very concerned about Bart getting drunk. This was why he drank the beer through a horn, to show that it was only accidental.^[3] This was a toned-down version of what was in John Swartzwelder's original script.^[4] Originally Chief Wiggum's first line was "They're either drunk or on the cocaine", but it was deemed too old-fashioned.^[5] The discovery of "more lines on the parchment" was a simple deus ex machina to get Homer freed and to end the episode.^[3]

When Homer first enters Moe's "Pet Shop", the man that tips his hat to him outside was a background character used in the early seasons.^[5] The riot at the beginning of the episode was taken from footage from the end of the season 6 episode, "Lisa on Ice", and updated.^[6] The line "To alcohol! The cause of, and solution to, all of life's problems," was originally the act break line at the end of act two, but was moved to the very end of the episode.^[7]

The episode parodies the series The Untouchables, with the character of Rex Banner based on Robert Stack's portrayal of Eliot Ness,^[1][8] and the voice of the narrator being based on that of Walter Winchell.^[5] Barney leaving flowers outside the Duff brewery is, according to show runner Josh Weinstein, a reference to people leaving flowers at the grave sites of various Hollywood figures like Rudolph Valentino and Marilyn Monroe.^[3] The shot of the diner references Edward Hopper's Nighthawks painting.^[3]

In its original broadcast, "Homer vs. the Eighteenth Amendment" finished 39th in ratings for the week of March 10–26, 1997, with a Nielsen rating of 8.9, equivalent to approximately 8.6 million viewing households. It was the second-highest-rated show on the Fox network that week, following The X-Files.^[9]

The authors of the book, I Can't Believe It's a Bigger and Better Updated Unofficial Simpsons Guide, Warren Martyn and Adrian Wood, called it "A nice episode in which Homer actually devises a clever plan to keep the beer flowing."^[1] The Toronto Star described the episode as one of Bob Anderson's "classics".^[10] The Daily Telegraph also characterized the episode as one of "The 10 Best Simpsons TV Episodes".^[11] Robert Canning gave the episode 9.8/10 calling it his favorite episode of the series.^[12]

Homer's line "To alcohol! The cause of, and solution to, all of life's problems," was described by Josh Weinstein as "one of the best, most truthful Simpsons statements ever".^[3] In 2008, Entertainment Weekly included it in their list of "24 Endlessly Quotable TV Quips".^[13]

A scene in which a British chip shop named "John Bull's Fish & Chips" blows up was censored in Britain and Ireland but it is no longer.^[14] This scene is shown uncensored on the Disney+ streaming service.
