Bob pretends to be stuck inside the walls of their house so he doesn't have to deal with Linda's parents in their house.
Meanwhile, Tina, Gene and Louise get in trouble in school.
- Actually Pretty Funny: After calling Linda Nag-atha Christie to mock her for nagging, Bob fires off a whole slew of nag-puns at the end. Linda is unamused until he gets to "Secretary of Nag-riculture", where she admits that one is pretty funny.
- Ax-Crazy: In Bob's hallucinations, Louise's nightlight immediately suggests killing his mother-in-law for bringing "An outside protein" to the restaurant. Rather than agree, Bob muses he turned mean pretty quickly.
- Didn't Think This Through:
- Bob never confirmed whether he was stuck or not in the wall, so he pretended to be, but as it turns out, he really can't leave the wall.
- Similarly, Frond, who got the kids out of the school without permission or their parents' approval, which amounts to essentially a kidnapping, something even lampshaded by Linda's mother to get him to back off from calling Social Services.
- Freudian Excuse: Tina says that her fetishes for zombies started when Bob left her alone with the movie Night of the Living Dead playing on TV, and her fears and budding teenage desire are getting mixed up.
- Like Mother, Like Daughter: Bob mentions Linda is looking more and more like her mother. Something that made Linda angry.
- Mama Bear: When Frond tries to call Social Services on the Belchers, Linda's mom immediately defends her daughter and son-in-law, saying they're great parents and that sometimes just drive each other a little crazy. She also points out that Frond doesn't really look good in this situation (since he took the Belcher kids out of school without telling the principal or the parents), either, which got him to back off.
- Nightmare Fetishist: Tina, who states that she has erotic dreams involving zombies.
- Obnoxious In-Laws: Bob can't stand Linda's parents, which annoys Linda.
- Oh, Crap!: Bob, twice. First when he overhears Linda's parents planning to stay longer, and then when he realize he's really stuck.
- The Calls Are Coming from Inside the House: Played with, by Bob.Bob: "The scream... it's coming from inside the wall!!"
- Sanity Slippage: Bob begins going insane while left alone in the wall after having a fight with Linda, to the point of talking with his night light and believing that there's a secret speakeasy in the walls.
- Linda says that the family sheds hair like a bunch of Chewbaccas.
- Several to The Shining, including the iconic bar and the "Here's Johnny" scenes.
- Gene makes a reference to the book The Lion, the Witch, and the Wardrobe.
- Tina says that her fetish for zombies comes from when she watched the 1968 Night of the Living Dead.
- Louise's friends refer to the movies Ghost and Ghost Dad when talking to Bob.
- Too Dumb to Live:
- The girls Louise brings over for a fake seance seem incapable of understanding the "Ghost" they're taking to is Louise's dad despite being told at least three times who he is, to the point Bob screws with them by saying he wants to eat their souls for being so annoying.
- Mr. Frond takes everything Louise tells him at face value and never even bothered to double check with or call Linda to inform her Louise is having problems because of her dad's supposed death.
- "Well Done, Son!" Guy: Tina, downplayed. She states that her father would be proud of her if she slept on the ceiling.
- What the Hell, Hero?: Linda was furious when she learned Bob pretended at first of being stuck between the walls just to avoid her visiting parents.
