The family ends up on an The 1900 House-type reality show after Lisa's newly-obtained hockey stick from a Russian player infests the house with termites.
Gilligan Cut: When a pipe fell on Homer's head at the plant, Burns was afraid he'd hold out for millions. Cut to the next scene with Homer and the family going to a hockey game to enjoy the skybox. And Homer didn't even realize it was a hockey game before Lisa pointed it out. In fact, several people didn't realize they were going to a hockey game until they read the sign at the stadium.
Good Is Boring: The Simpsons soon become much nicer after living a 19th-century, but ratings plummet.
End of an Age: This is the last episode produced in traditional ink and paint to air on the show.

While the Simpsons' house is being fumigated, the theme of King of the Hill is playing while they are waiting.

Bart: [opens the kitchen door and the termite-damaged knob comes off] Hey Mom, our crapshack's going to Hell. Marge: [offended] Bart, watch your potty mouth! [Homer suddenly falls through the ceiling onto the kitchen table while still seated on the toilet] Homer: [notices Marge and Bart] Hey, get out! I'm in here! [beat] Oh.
