Duffless/References

== Trivia ==
*During the tour of the Duff Brewery, the three vats are marked "Duff", "Duff Light" and "Duff Dry". The vats are filled by the same pipe, indicating different names for exactly the same product. This may be reference to an urban legend that some gas stations hooked up their regular, plus, and super unleaded to the same tank, charging more money for customers who bought plus or super while getting the same product.
**Related to this gag, this same scene has been used to show the aspect ratio differences between the original 4:3 as seen on Fox and on the DVD releases and the 16:9 versions seen on FXX and Disney+ prior to the latter allowing the option to view 4:3 ratio in pre-HD episodes. In the 16:9 version, the pipe is cropped out of view making it seem like they are indeed three different products.
*This is the first appearance of Sarah Wiggum (Chief Wiggum's wife).
*It is revealed Hans Moleman is 31 years old and looks old because of severe alcoholism (though later episodes would have him as 80 years old).
**This is also the second episode to imply that he was significantly younger than his appearance would suggest, as he was mentioned to have been born on August 2, 1961 on his driver's license in the episode "Selma's Choice" (which at the time of airing was on January 21, 1993, which would make him roughly that age).
*Martin had a flying balloon which was deflated when Nelson shot it from his B.B. Gun exhibit. Nelson states that he was aiming for Martin's head. In the syndicated version, both Martin and Nelson's exhibits at the Science Fair were removed. In the DVD release, this scene was left in uncut.
**Also cut in syndication is the scene of Chief Wiggum accidentally showing a home video of him eating a hot dog in a kiddie pool (and later spraying his wife with a hose) during the anti-drunk driving class.
*When Barney is talking to the quality control worker, one of the bottles that pass by is actually a jar with Adolf Hitler's head in it. Some bottles before the jar contains dentures, a small 3-eyed fish, and broken glass bottle neck.
*On Homer's fake ID, his name is listed as Brian McGee. His date of birth is also listed as August 2, 1948.
*Bart hurling Lisa's science experiment at Skinner's posterior while the latter was tying his shoes was similar to the Picture Day level in Virtual Bart, where the player can throw (regular-sized) tomatoes and eggs at Skinner's posterior while he is bent over and not get in trouble. Coincidentally, both this episode and Virtual Bart were released within the same year.
*Ned mentioned that he hasn't drank in 4000 days, which would be the equivalent to 10 years and 11 months.
==Cultural references==
* Lisa asks Bart to hold the giant tomato and Bart answers "Certainly" and laughs, in reference to a catch phrase of Curly Howard from the Three Stooges. Another Three Stooges reference is when Bart trying to pick up the cupcake and get electrical shock, and Bart responded "wise guy, eh?" and the iconic action of hands patting the face.
*Barney mistakes a pile of rags for Princess Diana.
*A commercial from 1960 with former United States Presidents Richard Nixon and John F. Kennedy is shown at Duff Brewery.
*Lisa laughs and says she just remembered a joke from the sitcom Herman's Head, a show that featured Lisa's voice actress Yeardley Smith and Hank Azaria.
* McMahon and Tate Advertising, from Bewitched, is shown during the Duff commercial where two beer truck drivers douse a trio of feminists protesting against Duff's sexist ads with beer and turn them into party girls in bikinis.
*At the end of the episode the song "Raindrops Keep Fallin' on My Head" is played while Homer and Marge ride a bicycle.
* When Homer was 17 years old, he listened to the British rock band Queen and had a poster of them on his wall.
**The "Very Good Beer" song Homer sings is a parody of Frank Sinatra's "It Was a Very Good Year".
* The scene where Bart is tempted to touch the two cupcakes is a reference to the scene in A Clockwork Orange where Alex is tempted to touch the woman's breasts as part of his treatment.
* Martin is dressed up as Phileas Fogg, the main character from the Jules Verne novel Around the World in Eighty Days for his science fair project.
* When Homer is pulled over under suspicion of being drunk and made to do a dexterity test, he ends up having to sing the Alphabet song while touching his nose and hopping from one foot to another, albeit with slightly modified lyrics.
*The final scene in which Homer and Marge ride off into the sunset singing B.J. Thomas' "Raindrops Keep Falling On My Head" parodies a similar scene in Butch Cassidy and the Sundance Kid.
*When Lisa goes to the pet store and asks for the most intelligent hamster they have, the shopkeeper gives her one by the name of "J.B McGregor" who writes mysteries. This is reference to the character of J.B Fletcher, the fictional character from the crime drama series Murder, She Wrote who also writes murder mystery novels.
== Censorship ==
* When Princess Diana died in 1997, the scene of Barney mistaking the pile of rags for Princess Di was cut from UK television.
== U.S. Syndication Cuts ==
The following scenes/shots were cut when aired on free-TV syndication, though not cable, streaming, or home media releases:
* The shot of the Prohibition Era Duff beer poster
* Three scenes at the science fair: a father yelling at his son to get away from the volcano he made for him, Martin's presentation on the hot air balloon and Nelson shooting at it from his "Wasting Squirrels with BB Guns" booth, and Nelson saying, "Dang! I was aiming for his head!"
* Homer sitting through Patty and Selma's Tupperware sales pitch, Selma scaring Jub-Jub (the pet iguana from "Selma's Choice") after putting the Tupperware tub on her head, and Homer muttering, "I would kill everyone in this room for a drop of sweet, sweet beer."
==Goofs==
*After Homer says "...send the kids to the neighbors I'm coming back loaded" he kisses Marge and she blinks with her eyelid being see-through.
*In the scene where Homer returns to Moe's Tavern, you are able to see two Larrys at once; sitting drinking beer amongst other patrons.
*It's impossible for Homer to be listening to Queen when he was 17. Since Homer is 37, and the episode was released in 1993, that means that he claims he was listening to Queen in 1973. He has a poster hung on the wall of the album , which was released on November 21, 1975, when Homer was 19.
*The fake ID card Homer shows has an age on it which wouldn't make sense, as the card's shown age would have to change yearly.
*The hamster is colored pink for most of the episode. However, at the science fair it is colored a more realistic brown.
