While still tripping on anesthetic after a trip to the dentist, Bob mistakes his sister-in-law Gayle for Linda and kisses her. Gayle becomes convinced they are now having an affair, and while Linda tells Bob to keep it going to give Gayle an ego boost, Bob tries to set her up with the family's playboy dentist Dr. Yap.
Meanwhile, Tina tries to make Dr. Yap fall for her using the techniques of the Prince of Persuasia, and Louise and Gene compete for a jawbreaker in several crazy contests.
Tropes:
- Abhorrent Admirer:
- Gayle is annoying to Bob, keeps following him and trying to get them to act as if they are having an affair, while Bob is clearly not interested.
- The Prince of Persuasia's techniques are guaranteed to turn anyone who uses them into this if not a flat out sex offender. His first step is basically trapping your love interest by cornering them and making them unable to leave you.
- All Love Is Unrequited: Tina wants Dr. Yap, who wants Gayle, who wants Bob, who is Happily Married to Linda.
- Bait-and-Switch: This exchange:Gayle: You don't remember? We made love!Bob: WHAT!?Gayle: With our mouths.
- When Yap shows the Belchers to their rooms at the cabin, Gene realizes he can say whatever he wants in Bob and Linda's soundproof room without consequence. It's obvious set-up for a joke where he says something rude or vulgar only to be loud enough for his parents to hear him. However, when he actually enters the room...Gene (muffled): I love my family!
- When Yap shows the Belchers to their rooms at the cabin, Gene realizes he can say whatever he wants in Bob and Linda's soundproof room without consequence. It's obvious set-up for a joke where he says something rude or vulgar only to be loud enough for his parents to hear him. However, when he actually enters the room...
- Bestiality Is Depraved: Implied. When Bob is making out with Gayle, she remarks that his tongue "feels different from her cat"—the obvious (and disturbing) conclusion being that she has done the same thing with her cat as well.
- Casanova Wannabe: Dr. Yap is extremely desperate for love, but he's got way too many issues in the way of that.
- Character Development: Gayle is far more well adjusted than in "Art Crawl", but she mentions having changed the meds she is on.
- Cosmic Plaything: Bob is unwillingly forced into a Love Dodecahedron by his wife and sister-in-law, has to endure getting one of his adult-teeth removed without any drugs by Dr. Yap (who thinks he is having an affair with his would-be girlfriend) and is nearly doghoused by Linda even though the whole thing was her idea.
- Double Standard Rape: Female on Male: Gayle's constant advances on an unwilling Bob (some of which border on sexual harassment) are played entirely for laughs. When Linda and Yap catch them in the act, they also both get mad at Bob even though Gayle is clearly forcing Bob into it.
- Early-Bird Cameo: The Prince of Persuasia would appear in-person at the end of next season, in "The Unnatural".
- Expository Hairstyle Change: Gayle sports a new hairdo, though it's implied she did so because she took meds that toned down her usual neurotic self. Sure enough, she's back to crazy in the following episodes and loses the hairdo.
- Green-Eyed Epiphany: Linda realizes that she hates the idea of Bob and Gayle having an affair even though she was the one who started it when she sees the two of them together and absolutely loses it.
- Green-Eyed Monster: Gayle tends to want anything Linda has or whoever she is dating.
- Hidden Depths: Linda and Tina already know how to ski due to going to a skiing charity event without the rest of the family. It doesn't get commented on, but Gayle's also surprisingly capable at skiing for someone like her.
- Humiliation Conga: Poor Bob gets continually sexually harassed by Gayle, has a tooth pulled with no anaesthetics, and is slapped by Linda because of something that was her own fault.
- Kissing Under the Influence: Bob is high on meds when he kisses Gayle, but she believes he was doing it consciously.
- Know-Nothing Know-It-All: The Prince of Persuasia. Nothing what he says about picking up women makes the slightest sense psychologically, socially, or biologically, yet both Tina and Dr. Yap believe his every word.
- Limited Wardrobe: Pretty much the only episode where Gayle averts this; depicting her in a pink shirt instead of her usual purple shirt. She also lets her hair down, and overall these changes make her look a lot more like her sister (with the pink shirt being closer to Linda's red shirt). This is all intentional, as it makes it much more plausible that a drugged-up Bob would confuse Gayle for Linda.
- Love Dodecahedron: Tina is in love with Dr. Yap, who's in love with Gayle, who's in love with Bob, who's Happily Married to Linda, who briefly pretends to be in love with Dr. Yap in order to get him hooked up with Gayle.
- The Mistress: Gayle sees herself as this, convinced that Bob is into her.
- No Sympathy: Linda is more than happy to let Gayle believe she's having an affair with Bob, even as Bob becomes increasingly uncomfortable and Gayle straddles the line at outright sexual harassment.
- Not What It Looks Like: During the ski trip, Gayle falls on Bob and makes sexual advances right when Dr. Yap and Linda see them, causing the two to assume that they're actually making out with each other.
- Screams Like a Little Girl: Dr. Yap lets out a high-pitched, childish cry when bemoaning his bad luck with women.
- Ship Tease: Between Gayle and Dr. Yap. While it seems to be going somewhere at the end of the episode, this is never mentioned again and both are back to their single status by their next appearance.
- Shout-Out: Dr. Yap takes dating advice from a hack pick-up artist that calls himself the Prince of Persuasia.
- Unwitting Instigator of Doom: Linda letting Gayle drive to the dentist and pick up Bob leads to him kissing Gayle while high on meds, causing her to fall in love with Bob. Bob even calls her out at the end of the episode.
- Wrestler of Beasts: Invoked and discussed. The Prince of Persuasia says that one way to get a girl to like you is to make up a story about fighting and killing a wild animal.
