Goof: Santa's Little Helper is seen in the flashback despite the fact that the Simpsons did not get the dog until Christmas when Bart was ten and Lisa was eight.
Goof: In the 1985 flashback, when Marge is crying about Homer telling her he must act like he's not married during his tour of Sweden, on the wall over the bed is a photograph of Lisa in her present day and age, despite the fact she would be a toddler. To the right of it is a picture of Maggie, despite the fact she wasn't born yet.
Goof: When the Be Sharps are singing at the Centennial Celebration of the Statue of Liberty, the voice of Chief Wiggum can be heard, despite the the fact that he was replaced by Barney Gumble in the group.
In this episode, we find out that in the mid-80's Moe's was named "Moe's Cavern."
When Homer's barbershop quartet is singing at the church, the marquee outside says: "Today: What a f iend we have in God. Also: The Be Sharps."
However, the group doesn't get that name until later in the episode, after Barney joins the group.
If you look closely on top of Moe's at the end of the episode you can see Edna Krabappel's number, it is 555-6921.

Poo poo pa-doop...

Homer: I pity the fool who doesn't like... he. And where's Barney?
Skinner: Oh, he's with his new girlfriend, the Japanese conceptual artist.
(Barney and his girlfriend walk in, and Barney inserts a demo tape into a recorder)

(On the recorder)

Reporter: Principal Skinner, you've been referred to as "the funny one." Is that reputation justified?
Skinner: (seriously) Yes. Yes, it is.
Reporter: I have a question for Apu du Beaumarchais. Isn't it true that you're really an Indian?
Apu: By the many arms of Vishnu, I swear it is a lie!
Homer: Well, one of us made some money. I sold a guy our spare tire. (the tire blows out) D'oh!

Homer: Shut up!
George Harrison: Hello, Homer! I'm George Harrison.
Homer: (incredulous) Oh my God. Oh my God! Where did you get that brownie?

At the end of this episode the words "Dedicated to the memory of Michael P. Schoenbrun" shows up before the Gracie Films logo appears. Schoenbrun was a production manager on a number of television projects, including the 1966 series Misson Impossible. For the Simpsons, he was the executive in charge of production on the Season 4 episode, "Kamp Krusty".
Blackboard Joke: I will never win an Emmy.
Couch Gag: The family shatters like glass when trying to run to the couch (in the original, there are two more takes: one has the family meld together into a blob and the last take has the family explode on contact. These have been removed in syndicated versions).
"The Be Sharps" vocals were sung by "The Dapper Dans" who are: James Campbell, George Economou, Shelby Grimm & Dan Jordan.
John F. Kennedy
Mayor Quimby's '"Ich bin ein Springfield Swap Meet patron" line is similar to a Kennedy quote, "Ich bin ein Berliner."
The Be Sharps are based heavily on The Beatles. Here are some references you may have spotted:
The Beatles played their first gigs at The Cavern Club; The Be Sharps played at Moe's Cavern.
A member is replaced.
The album ''Meet the Be Sharps'' and its cover.
Nigel's line, ''You've just recorded your first number one.''
Apu changing his surname from "Nahasapeemapetilon" to "de Beaumarchais" is a reference to Ringo Starr having changed his name from Richard Starkey. Barney's girlfriend looks like Yoko Ono, John Lennon's girlfriend and the track ''Number Eight'' is a reference to Beatles' track, ''Revolution No. 9.''
The ''Bigger Than Jesus'' joke.
The ''Coop coop a-doop'' line from one of the songs is similar to the ''Goo-goo-a-joob'' line from ''I Am The Walrus.''
The final rooftop performance is something The Beatles did; in fact, George Harrison passes by in this scene and says: ''It's been done'', referring to himself.
The fans shouting "Wiggum forever, Barney never!" then "Barney forever, Wiggum never!" is similar to when Ringo Starr replaced Pete Best as drummer. Fans of Best would fight at the Cavern Club, shouting "Pete forever, Ringo never!" Other fans shouted the contrary, "Ringo forever, Pete never!"
Principal Skinner: Ah, prisoner 24601.
The number of Jean Valjean in the famous movie/musical/novel "Les Miserables" (also used as Sideshow Bob's first prison number)
Homer's Song: "It's Not Geraldo's Fault"
Homer's first song (the one with the lyrics "There was nothing in Al Capone's vault, but it wasn't Geraldo's fault.") mirrors an incident in 1986 where Geraldo Riveria searches for a treasure in Al Capone's vault, only to find nothing.
Alvin and the Chipmunks
Melvin and the Squirrels, whose record is on sale at the Springfield Swap Meet, is a parody of the novelty recordings of "Alvin and the Chipmunks."
Groundskeeper Willie: "When yea're alone and life is gettin' you lonely, ye can always go, ACH!Doon-toon."
Willie mangles the 1964 #1 hit for Petula Clark, "Downtown," in his audition for the Be Sharps.
