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.
The narrator states that the Simpsons are a "Northern Kentucky" family, finally ending the age old question of the show and it makes sense according to the other clues. This was meant to give a sense of conclusion as this was the last episode of the season and many fans and even show runners thought the show was on its last leg.
Bart states he never said "Cowabunga, dude!" in his life, before joining the show. This is a reference to the line being a catchphrase for Bart even though he only said it once in a season 1 episode.
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.
The Blue-haired Lawyer atypically has black hair and red-framed glasses in this episode. Given the meta nature of this episode, he might use hair dye or a wig and a different pair of glasses for the series, compared to his "real world" appearance shown here.
Most of the names in the opening credits are grouped by category (for example, co-executive producers grouped together, etc.), but when the "Produced By" credits appear, Richard Raynis and Bonita Pietila are grouped together, while Denise Sirkot and Richard Sakai's names are shown individually.\
