First Aired - 2/7/1991
Homer gets an illegal cable hook-up, which causes Lisa to worry for her father's soul, as she learned about the 8th Commandmentnote in Sunday school ("Thou shalt not steal") and begins seeing theft everywhere she looks.
- Adult Fear: While Lisa's nightmarish Imagine Spot shows her fears of going to Hell depicted in Fire and Brimstone Hell style, Homer's shows his fears of being isolated from his family (or at least everyone but Bart).
- Being Good Sucks: Homer misses the match and deprives himself of cable after his conscience gets the better of him.Lisa: Dad, we may have just saved your soul.
Homer: Yeah, at the worst possible time!
- Call-Back: While Homer is watching TV, one sound clip heard is Scratchy saying "Lemonade?"
- Characterization Marches On: It seems unusual for Lisa to be so gung-ho about Christian morals after she's been a Buddhist for several seasons, not to mention more concerned with the environment and social justice than her own moral status. She still would not be okay with Homer stealing, of course, but the point is that there would be another reason for it than the one of this episode.
- Corrupt Cop: Some cops show up at the Simpson residence upon being informed Homer has an illegal cable hook-up. Homer is initially afraid they're there to arrest him but they tell him they just want to watch the match.
- Digital Piracy Is Evil: This trope is played remarkably straight. Even the guy who hooks up the cable is later shown to be stealing car stereos and breaking into houses. Homer, who's shown to have stolen from Moe's and work and is an unabashed alcoholic and Jerkass, comes to view this (although only after Lisa and Marge guilt-tripped him to the point he gave in) as a kind of evil even he can't support.
- Dirty Kid: Bart takes a liking to the adult programming on Top Hat Entertainment, and charges all the other boys in the neighborhood to come watch it.
- Distant Prologue: "Mt. Sinai: 1220 B.C."
- Early Installment Weirdness: When Homer says he only invited a few close friends to watch the fight, and then Apu shows up, it's meant as a joke: the idea is that Homer has actually invited anyone and everyone to watch the fight, even if they're less a "close friend" and more just a "guy I see at the convenience store a lot". Since this episode aired, however, the show has really built up the friendship between Apu and the Simpson family, to the point where him showing up at a gathering of Homer's close friends would make complete sense.
- Funny Background Event: Jimbo Jones can twice be seen stealing things in the background, at the supermarket and later at the Kwik-e-Mart.
- Holier Than Thou: Lisa really lays it on thick over the Eighth Commandment. When she guilts Marge into paying for two grapes she sampled at the grocery store, the clerk is annoyed that he has to call in a price check for two grapes.
- Insistent Terminology: When Mr. Burns shows up to watch the fight, Homer tells Bart to hide the stuff he "borrowed" from work. Bart won't obey until Homer admits that, by "borrowed", he actually means "stole".
- Insufferable Genius / Rightly Self-Righteous: Lisa and Marge guilt trip Homer into giving up cable. Homer eventually admits defeat, but tells them he loathes them for it. They just smirk in response. Earlier, Lisa did the same to Marge over testing two grapes in store, Marge was similarly annoyed by it while Lisa just smiled. She's right and both sides sure know it.
- Missing the Good Stuff: In addition to guilt-tripping him into accepting that stealing cable is wrong, Marge and Lisa guilt-trip Homer into staying outside the house while the boxing match is on (and Homer forces Bart to stay outside, too). As a result, while a large number of people are inside partying, the Simpsons males are suffering in silence.
- No Celebrities Were Harmed: Drederick Tatum is a parody of Mike Tyson. His opponent Watson is based on Marvin Hagler.
- O.O.C. Is Serious Business: The normally friendly Ned is furious that he was offered illegal cable hook-up and yells at the shady cable man to leave.
- Parallel Porn Titles: The two adult films Bart watched were "Stardust Mammories" and "Broadcast Nudes".
- Reality Ensues: Lisa forces Marge to admit she ate two grapes to a grocery store clerk. Rather than comically overreacting, the clerk does not care and openly mocks Marge for asking to be charged for them.
- Soapbox Sadie: From the moment Lisa learns about the commandments (especially the eighth, "Thou Shalt Not Steal") she gets on it and guilt-trips her entire family into accepting that stealing is wrong and getting varying degrees of humiliation as a result (Marge is insulted by a jackass clerk and Homer accidentally cuts the power to the entirety of Evergreen Terrace trying to cut the cable).
- Special Guest: Phil Hartman as the Cable Guy, Moses, and Troy McClure
- And a bunch of the voices on TV. They really got their money's worth out of Hartman's appearance!
