- The plot of the episode is similar to The Prince and The Pauper, a story where a poor boy and a prince decide to live each others' lives.
- When Marge is washing the dishes, the song she sings to them ("Scrubbin' You") is a spoof of "Lovin' You" by Minnie Riperton.
- When Bart is looking at the different mansions, he sees McDonald's and Macaulay Culkin.
- When Mick Fleetwood and Stevie Nicks are seen in Springfield Heights, the pose they are in is identical to how they appear on the cover of the Fleetwood Mac album Rumours.
- The behavior of the Vac-U-Bots resembles the one of the leeches from Resident Evil Zero.
- In the TV6 airings of this episode, the episode's blackboard and couch gags are cut.
- Marge apparently drank a bit of alcohol when she expected Bart, causing him to be a prankster.
