Mr. Burns has The Simpsons house-sit for him while he goes to the Mayo Clinic, and Homer uses Mr. Burns' mansion and wealth to hold a booze cruise for his buddies.

* BitingTheHandHumor: Homer calling out everyone in the credits over being richer than he is (including the voice actors, who aren't as rich as they should be, but still are richer than he'll ever be).
* LoopholeAbuse: Homer would take Mr. Burns yacht to international waters just so Moe would be able to sell beer on a weekend before 2:00pm. Barney pointed out Moe could legally ''give'' beer. Moe doesn't budge.
* OffModel: According to, Britney Spears was drawn more like Baby Spice from The Spice Girls, though her character design was meant to look like Spears from her "Baby One More Time" video.
* OlderThanTheyLook: The search for Springfield's oldest resident reminded us of Ned Flanders' real age.
* SelfMadeOrphan: When Mr. Burns filled a form, he had to inform his parents' cause of death. He wrote "Got in my way".
* TakeThat: When Homer moaned that he never got any award, Marge reminded him of [[Recap/TheSimpsonsS5E1HomersBarbershopQuartet his Grammy]], prompting him to say he meant an award worth winning. Then we're shown a disclaimer stating Homer's opinions don't necessarily reflect those of the network, [[BaitAndSwitchComment who doesn't consider the Grammy an award at all]].
** {{Irony}}: They made that joke on an episode that had someone who won a Grammy at the time of the episode's premiere (BritneySpears)
* UnusuallyUninterestingSight: While Marge is cleaning Mr. Burns mansion, one of the rooms she tidies is his secret laboratory. She nonchalantly wipes dust away while ignoring the bizarre and horrific experiments around, including several jars containing clones of Burns and Smithers.
