Tropes:
- Alpha Bitch: Mrs. McGillicudy is this in The Retirement Home because she is the one with the largest Hummel collection. She uses her position to bully the rest of the inhabitants of the retirement home into exchanging drugs for more Hummels with birthday entertainers.
- Ass Shove: The guy dressed up in the Chuck E. Cheese had two Hummel figurines up his rectum. Apparently, every single birthday entertainer that died from a drug overdose had these inside their rectal cavity.
- Beta Bitch: Mrs. McGillicudy's two friends, who follow her everywhere.
- Breather Episode: This is one of the two Season 21 episode in which no mention of Cartman and Heidi's relationship is made, the other being "Holiday Special". Not even the Running Gag of Heidi talking to Cartman only for him to appear bored shows up.
- Cliffhanger Copout: The episode ends with Marcus walking in on a Pharmaceutical Doctors Convention to ask them some questions. Nothing comes out of it, however
- Children Are Innocent: Marcus, and seemingly other children too, genuinely believes that the birthday performers are the very same characters they are dressed up as.
- Continuity Nod: To South Park: The Fractured but Whole of all things. The Retirement Home sequence from the game is referenced when Cartman, Kenny, Kyle, and Butters form a quartet to cause a distraction.
- Faux Affably Evil: Mrs. McGillicudy. She acts sweet, but everyone can see just what a despicable person she is.
- Gasshole: Mrs. McGillicudy, who is constantly passing very quiet farts that sound like a deflating balloon.
- Genius Ditz: Marcus manages to figure out the plan with the retirement home and the Hummels... but he still doesn't know that the "Chuck E. Cheese" that died (as well as the other "characters" that died of overdose) was just a guy in a costume.
- Gilded Cage: The retirement home.
- Good Is Not Nice: Marcus wants to avenge Chuck E. Cheese's death, but he's rather abrasive about it.
- The Heavy: While the Pharmaceutical Doctors are behind the drug ring in the retirement home, its Mrs. McGillicudy that causes so much misery in said retirement home.
- Malaproper: Cartman refers to his barbershop quartet as "Young Prostitutes" after they were asked if they were the "Young Protestants".
- Product Placement: When Stan visits Kyle's house to ask his friends for assistance in helping his grandpa, Stan's friends are shown playing Rainbow Six Siege.
- Shout-Out: "Two Princes", "When I Come Around", "Milkshake" (by Kelis), "Rape Me", and "Insane in the Brain" are sung by Kyle, Kenny, Butters, and Cartman.
- Grandpa Marsh beating Mrs. McGillicudy with a bag of Hummels is very similar to the scene where one inmate beats another with a bag full of unopened soda cans in the 1983 film Bad Boys.
- Take That!:
- Towards retirement homes, comparing them to prisons.
- Also towards people who collect figurines of sorts and treat it as Serious Business rather than a small, fun hobby.
- The Man Behind the Man: It's implied at the end that Pharmaceutical Doctors are the ones behind the drug ring and that Mrs. McGillicudy was simply distributing the drugs for them.
- Tranquil Fury: Just before beating the shit out of McGillicudy and her cahoots, Grandpa Marvin coldly responds with a "Yes" when confronted as well as if he thinks having the Hummels makes him the "top bitch".
- Unusually Uninteresting Sight: The doctors performing autopsies (and the police officer standing watch) don't seem to think that the hummel figurines hiding in the overdosed part performer's asses are worth looking into. Apparently its so common, they just think that's a normal thing to find in overdose victims.Marcus: And you do not find this "out of the ordinary?"
Doctor: Not at all. - The Voiceless: Mrs. McGillicudy's two friends never speak in the episode and only open their mouths to groan in pain when Marvin attacks them.
