Monty Burns' Fleeing Circus - S28-E1

Trivia: At one point in this episode Homer is talking about the drink named after golf legend Arnold Palmer. This episode coincidentally aired the same day that Arnold Palmer died.

Phaneron

Two Bad Neighbors - S7-E13

Trivia: When the episode was written, the show's writers were unaware there was a real George Bush, Jr (e.g. George W. Bush). The intended joke was that, in one of his usual moments of idiocy, Homer had invented a fake son.

Four Great Women and a Manicure - S20-E20

Trivia: Bart does not appear at all in this episode.

Krusty Gets Kancelled - S4-E22

Trivia: The scene where Bette Midler sings to Krusty is an allusion to Johnny Carson's penultimate episode as host of The Tonight Show where Midler was his final guest and sang to him.

Phaneron

Coming to Homerica - S20-E21

Trivia: During the couch gag, the Simpsons run through different places (as spoofs of different TV shows). One of the places they run through is the bar from Cheers. When they all sit down, Sideshow Bob walks through the door. Kelsey Grammer does the voice of Sideshow Bob, and starred as Doctor Frasier Crane in Cheers.

The Old Man and the Key - S13-E13

Trivia: When Grampa, Crazy Old Man and Jasper are about to race Snake, and his girlfriend is there, the girlfriend is Gloria from "Hunka Hunka Burns in Love."

Behind the Laughter - S11-E22

Trivia: In this episode the Simpsons are labeled finally as a "northern Kentucky family"; this was quickly enough dismissed as a red herring for various reasons. To further mystify, however, if you turn on the English subtitles on the episode, they say "southern Missouri family".

The Old Blue Mayor She Ain't What She Used To Be - S29-E6

Trivia: When a man falls into the Springfield Cactus Plant after sliding down a wire to escape the panicked crowd, he yells a Wilhelm scream.

Radioactive Man - S7-E2

Insane Clown Poppy - S12-E3

Trivia: When Homer is looking at he blueprints for the dog kennel, he says he'll finish it in 2007. In the 2007 Simpsons movie, Santa's little helper gets a new kennel to replace the one that was destroyed earlier in the film.

Day of the Jackanapes - S12-E13

Trivia: The episode title is a reference to The Day of the Jackal, but the plot more closely resembles The Manchurian Candidate.

Cape Feare - S5-E2

Trivia: The gag of Sideshow Bob stepping on the rakes was only supposed to be him stepping on a single rake one time. But the episode's running time was short, so the sequence was extended as a time filler.

Homer's Odyssey - S1-E3

Trivia: Smithers made his first appearance in this episode but he was mistakenly animated with the wrong colour. He was made into an African American with blue hair. This was corrected in the episode "There's No Disgrace Like Home", where he appeared in his normal yellow colour.
