VH-1 allowed the crew to modify Behind The Music's visual graphics package for use throughout the episode.
The name of the episode is also what inspired the name of the Behind the Scenes section of SimpsonsWiki called "Behind the Laughter."
A scene depicted Homer and the cast looking at an episode they just completed in which the family talk about visiting Delaware. Homer mutters to the director, "This'll be the last season." The whole quote is used by the family when they're in the airport in the Season 12 finale, Simpsons Tall Tales.
Queen Elizabeth also appears in this show, laughing at the Simpsons on TV. The Queen was also worked into "The Regina Monologues" four seasons later, albeit in conflict with the Simpson family.
While living in MC Hammer's mansion, Homer has a pot-bellied pig named Mr. Porky; Homer would get a second pig in The Simpsons Movie, who is referred to as his "summer love" in a contemporary couch gag.
The narrator states that the Simpsons were a "Northern Kentucky" family. This would not fit into the series Canon because in one of the episodes, Homer stated that he's "never been to Kentucky" and in another, he says he's lived in the same state most of his life. This only underscores the ambiguity of where the Simpsons live. Also, the DVD subtitles say "southern Missouri" and several state locations instead of "northern Kentucky", emphasizing the gag.
Bart states he never said "Cowabunga, dude!" in his life, before joining the show.
In Lisa's tell-all book, she revealed that she is given anti-aging hormones. This is mostly likely a joke referring to how despite the many years the show has gone on they have yet to age. However, the intent was a barb at Gary Coleman, who had sued his parents claiming they secretly dosed him with anti-growth drugs in order to prevent his body's natural growth.
When the screaming fans are shown watching Bart skateboard, there is a "Hysteria Ward" sign shown, but the joke would require the sign to be inside the room, instead of outside-leading-in as most signs are displayed. Patients themselves would not need a sign telling them what room they're inside.
On the "Behind the Laughter" title screen, the top-left repeatedly contains a clip of Homer wrangling the grease hose from Lard of the Dance with which he sucks his eyeball out of its socket.
