This episode was nominated for the 2001 Golden Reel Award for Best Sound Editing - Television Animation - Music. (edit) Blackboard Joke: I will not dance on anyone's grave.
Couch Gag: The family is swinging on vines in Tarzan-style clothes. Homer swings past the couch and crashes off-screen. (edit)

Vicky: I'm sorry, but giving everyone an equal part when they're not clearly equal is what again, class?
Girls: Communism! (edit) Ralph: Lisa's bad dancing makes my feet sad! (edit) Lisa: What am I doing wrong?
Vicki: Well, you're falling a lot. Maybe you should work on that. (edit) Homer: Now, honey, what were you trying to say before we kept interrupting with our loving proudness?
Marge: Yes, our tiny tapper, what was it you were going to say after "I wanted to be a dancer, but"?
Lisa: But, I just... need more practice! See ya! (exits kitchen, her shoes tap)
Homer: Oh, what's that awful sound?
Marge: The furnace?
Lisa: It's me!
Homer/Marge: Aww.... (edit) Vicki: You've just got to turn that frown upside-down!
(Lisa smiles.)
Vicki: That's a smile, not an upside-down frown! Work on that, too! (edit)

Where did Lisa's shopping bags go after the movie? Her and Marge both had two when they were looking at the title outside, and then when the come out, Lisa's are gone. (edit) When Professor Frink claps the can moves but when he puts the microchip in Lisa's shoe it is off. (edit) In the scene where the three bullies (Dolph, Jimbo, and Kearney) kidnap a blind Homer and make him go to the liquor store to get Jack Daniels and cigarettes, Jimbo's hat is mustard yellow instead of the usual grape purple. (edit)

The series Homer watches at the beginning features a robot similar to Robo Cop. (edit) :
When Milhouse is scared by seeing the lion's on the other side of the plant they're hiding in, he is scared speechless and communicates only by pantomine and whimering and growling. That is a parody of "Scooby-Doo" when Scooby sees a monster near them and pantomines the monster. (edit) :
The MORG synthesizer featured at Stan's Keyboards (a store at the Springfield Mall) combines the Moog synthesizer and the Korg keyboard brand names. (edit) :
The main inspiration for the episode's climax – Lisa tap-dancing uncontrollably while wearing a pair of red slippers and unable to remove the Professor Frink-altered shoes – is found in Hans Christian Andersen's "The Red Shoes" (wherein a ballerina wears a pair of cursed slippers that won't stop dancing).

A similar plot was found in the Warner Bros. animated classic, "The Wearing of the Grin," where Porky Pig – accused by a pair of paranoid leprechauns of attempting to steal their gold – is sentenced to wear a pair of magic green shoes that cause him to continuously dance a jig. (edit) Chief Wiggum: We'll catch that mallrat.
"Mallrat" is slang for young teen-agers who hang out at the mall, basically just to hang out, bother customers and store owners/employees, and generally cause trouble. Shown in Kevin Smith's 1995 film "Mallrats." (edit)
