In part one of this trilogy episode centered on a meteor shower, Cartman's mom goes to a meteor shower party, and leaves her son with Shelly, Stan's violent sister. Meanwhile, Cartman's cat, Mr. Kitty, is in heat and goes searching for sex with other cats.
This episode provides the following:
- Ankle Drag: Shelley clutches onto Cartman's ankle when she chases him up the stairs. A reference to Aliens where Ripley gets this treatment from the Xenomorph.
- Aside Glance: Mr. Kitty does this after first encountering the fat orange cat.
- Babysitter from Hell: Shelley is abusive towards Cartman.
- Big "NO!": When Skyler discovers his trashed guitar.
- Borrowed Catchphrase: Skyler makes a variant of Cartman's once he breaks up with Shelly.Skyler: Screw you, bitch, me and my kickass guitar are going home.
- Can't Stop the Signal: Cartman claims he sent evidence to the press which he hopes will keep Shelley from killing him.
- Cassandra Truth: Cartman eventually gets through to his mother but she doesn't believe his claim that Shelley is having her boyfriend over.
- Character Development: Cartman at first treats Shelly like his mother, yelling at her and ordering her around like a slave, but when that repeatedly fails he decides to calmly manipulate her and play with her emotions instead, a step towards the Manipulative Bastard he'd become in later seasons.
- Continuity Nod: When Shelly and Skylar are eating the pizza in the kitchen, magnets of Fluffy and Kyle's elephant can be seen on the fridge in reference to "An Elephant Makes Love to a Pig".
- Damsel in Distress: Cartman's Selma Hayek doll in the opening scene.
- Early-Installment Weirdness: This episode was made when Cartman was just a stupid Spoiled Brat, so him showing empathy and being nice to Shelley (especially after Skyler dumps her) might seem strange to someone who's only seen Cartman's personality in the later episodes.
- Ephebophile: Skylar. He’s 22 and was only dating Shelly because he assumed he could have sex her, when she refused he dumped her.
- Even Evil Has Standards: Even Cartman is freaked out that Shelley has a 22-year-old boyfriend. Shelley also realizes that when Skyler dumped her because she won't put out.
- Everyone Has Standards: Skyler's bandmates are grossed out by him dating Shelley because she's underage and nearly a decade younger than he is.
- Evil Versus Evil: Shelley babysitting Cartman. Both of them then team up and go against Skyler.
- Garage Band: Skyler and his band don't even have a garage for practice so they come over to Cartman's house.
- Get Out!: Skyler tells his bandmates to do this when they criticize Shelly's song and the fact that he's dating her.
- Giftedly Bad: Skyler as a songwriter and musician.
- Held Back in School: Skyler is 22 and still in high school.
- High on Catnip: Mr. Kitty brings her tomcat friends in the house, dumps catnip on the floor, and one of the cats snorts it. And then... Well, see the episode's title.
- I Can Explain: Cartman's reaction when his mother comes home while the house is in disarray.
- I Just Want to Be Loved: Shelley, who dates the inappropriately aged Skyler because she isn't pretty nor popular enough at school for her peers to date.
- Jerkass: Skyler. He's a stuck-up arrogant douche who tries to have sex with an underage girl. Once she refuses, he immediately dumps her.
- Laser-Guided Karma: Shelly wrecks Skyler's guitar that he stated was important to him and sticks the parts into a cat's litterbox and when he shows up back at Cartman's house, Cartman throws the catnip from the cat orgy on him and the cats attack him off-screen and even rip his pants off.
- Let's See YOU Do Better!: Shelly criticizes the band's sound and the bassist dares her to do better. She then produces the turd song.
- Pet the Dog: Cartman's helping Shelly get revenge on Skyler. Shelly also allows Cartman to go with her to see the meteor shower out of a rare moment of kindness after he tearfully tells her that he misses having a sibling.
- Priceless Ming Vase: Skyler points out how awesome and scratchless his guitar is. Needless to say, it's trash by the end of the episode.
- Shout-Out: Cartman parodies Newt from Aliens several times, with a play on her original line of "They mostly come at night....mostly" (referring to the alien).
- Synchronous Episodes: This episode is the Cartman portion of the "Meteor Shower" trilogy, which depicts the same evening through the POV's of the four main kids (Stan's tale is in "Two Guys Naked in a Hot Tub", while Kyle and Kenny's are told in "Jewbilee").
- Take That!: Throughout the episode, while playing with his toys, Cartman makes allusions to Wild Wild West. Coincidentally, the film was released on the same day as South Park: Bigger, Longer & Uncut, two weeks before the original broadcast of this episode. Those at South Park were disappointed that Wild Wild West performed better at the box office than their film despite being critically panned, and some underage moviegoers snuck into the R-rated South Park film after having bought tickets to the PG-13-rated Wild Wild West.
- Truth in Television: That whole "20-something guy flirting with a 12-something girl" doesn't come out of nowhere — it was very common for young girls in the '90s to have an "older boyfriend" and even sometimes being proud of it with the other students.
- Unusual Euphemism: Lianne tells Shelley to remind Cartman to wipe when he "makes bears."
- Waxing Lyrical: When Cartman takes the picture of Shelly and Skyler kissing, he exclaims "Ha ha! Charade you are!" which is the refrain of the Pink Floyd song "Pigs (Three Different Ones)" from Animals.
- Wedgie: A Running Gag of Shelley and her boyfriend pulling this prank on Cartman.
- We Need a Distraction: Cartman uses his Selma Hayek doll to lure Skyler away from his house.
- Your Tomcat Is Pregnant: Played with. Mr. Kitty is female but was given a male name probably because of gender confusion.
