* CitizenshipMarriage: Lisa says she might consider getting married someday if it ever becomes necessary to protect a Chinese dissident from deportation.
* EverythingIsBetterWithPrincesses: [[SubvertedTrope Subverted]]. When Bart and Milhouse lured frogs towards the church, some where passing through what seemed to be a palace's garden and a princess was kissing as many as she could in order to turn one into a prince. Turns out the "princess" was a mental hospital patient and the "palace" was where she was staying.
* OpeningShoutOut: The couch breaks during the CouchGag (where The Simpsons go skydiving), which then leads to it being broken in the show proper, the first time the opening segues directly into the main action. Homer then comments on all the times they've sat on the couch. The episode proper starts with the Simpsons' roof and it's shown there's a patch covering the hole made there during the crash.
* StrangeMindsThinkAlike: When Ned Flanders told Bart Reverend Lovejoy was in a place full of sulfur and exposed flesh, Bart realized Flanders meant Lovejoy was selling hot tubs.
