When Lisa finds the horse's head in her bed and screams, it is a reference to The Godfather. Also, the music from the original horse head scene is recycled.
The footage of Homer trying to blow-dry Lisa's hair at one point is recycled from "Bart the General".
The footage of Lisa calling Homer at work to say she loves him is recycled from "Bart's Dog Gets an F", as you can clearly see Lisa has the mumps in this scene.
The owner of King Toot's appearance is based on actor Wally Cox.
This episode reveals that Lisa had her pearls since she was a baby.
A kid sings his own version of Chuck Berry's song " My Ding-a-Ling", which due to its heavy use of double entendres, was one of Chuck's least known hits, namely done as a call-and-response song with live audiences. Principal Skinner forces the child off stage after singing one verse, angrily proclaiming "This act is over!"
When Sherri and Terri are doing their act for the talent show, they are wearing patriotic leotards reminiscent of Wonder Woman.
Approximately sixteen minutes into the episode, Ralph and another boy are talking about Lisa's handling of the pony Princess. The other boy says "She's certainly tamed that horse" and Ralph says "Yes, but what man can tame her?" However, when he speaks, it is in Nelson's voice. Not only are both Ralph and Nelson voiced by Nancy Cartwright but both go on to date her. The most likely explanation is that scriptwriters placed 'Nelson' on the script while the animators were told to draw Ralph.
Lisa says that she called Marge about the reed, but to no avail. In the next scene, Marge is seen at the talent show. This raises the question as to why Marge didn't simply take Lisa to the store. There is the chance that Marge was already on her way to the talent show.
Chuck's hair is blue. He is normally seen with either blonde or sometimes brown hair.
