Insane Troll Logic examples in Family Guy.
- In "Screwed the Pooch" when Brian is fighting for custody of (what he thinks are) his puppies:Lawyer: Mr. Griffin, which of the following two phrases best describes Brian Griffin: Problem Drinker or African-American Haberdasher?
Peter: Uh, do I-I guess problem drinker, but that's uh-
Lawyer: Thank you. Now: Sexual deviant or magic picture that if you stare at it long enough, you see something?
Peter: Well, sexual deviant, but that other one's not even, eh-
Lawyer: Thank you. - In "PTV", the FCC has a meeting over an incident where someone's genitals were exposed on live TV. One of the men in the meeting says they received twenty calls complaining about the event and goes on to say that one person equals a billion people. Therefore, twenty callers equals twenty billion people. This is ignoring the fact that the world doesn't even have half that many people.
- A Running Gag in the series combines this with Paper-Thin Disguise in that a character (Peter and Mort) pretends to be something they're not (Peter in "Patriot Games" pretending to be a cowboy astronaut to impress his high school classmates at a reunion, and Mort in "Road to Germany" disguising himself as a Catholic priest to get through Nazi Germany unhindered), and the disguise is blown all because some normally easily-removed article of clothing is...well, easily removed. (Peter's cowboy hat, and Mort's priest collar). Additionally, Mort is exposed when a real priest walks up, and the Gestapo officer looks confused and says "What? TWO priests?!" — as if there can't possibly be more than one priest in any one spot.
- In "No Meals on Wheels" Peter proves that (in his words) "cripples aren't cool". His favorite actor, Mark Harmon, doesn't need a wheelchair. Mark Harmon is cool. Therefore people who need wheelchairs aren't cool and shouldn't be allowed in his restaurant.
- In "McStroke", when Peter decides to grow a mustache:Lois: Oh! I think it's sexy!
Brian: I think it's gay.
Peter: It's not gay, Brian. If I'm gay, then Freddie Mercury was gay.
Brian: Freddie Mercury, the lead singer of Queen? He was incredibly gaynote .
Peter: He was not. He had a mustache, which is practically like a wedding ring. - In "When You Wish Upon a Weinstein" Lois, in a fit of rage, exclaims, "Sometimes I feel like I'm married to a child!". Peter replies that if she's married to a child, then she's a pedophile, and that he'll be damned if he'll stand there and be lectured by a pervert.
- Lois explaining to Chris in "Excellence in Broadcasting" that everything Fox News reports on is a lie. Even if it's true, it instantly becomes a lie if Fox News mentions it. Note that this is used to explain away the earlier revelation that Rush Limbaugh and Fred Savage were the same person, something Lois herself discovered and reported on for Fox.
- In "New Kidney in Town", Peter tries making his own Red Bull, and uses mostly kerosene, reasoning that Red Bull and kerosene are both fuel, so kerosene equals Red Bull. When Brian points out the sheer insanity of this and the fact that the drink will probably kill Peter, Peter responds with "Brian, whatever kills me makes me stronger".
- "Who cares what you think, you're a dog. You can't see colors, which means you can't see the colors of the American flag. Commie."
- In "Quagmire's Mom", Peter tries to proclaim Quagmire's innocence by claiming that he was born on February 29th and therefore, he's only 12 and therefore he was the one who was raped and not the underaged girl he slept with.Peter: Argo, Ben Affleck.
- In "Airport 07", when Peter sees Quagmire's plane being fuelled, he starts imagining his pickup flying through the air Top Gun style because according to him (and because he doesn't remotely know anything about aerodynamics), if he can get his pickup to run on the same fuel as a plane, and a plane is able to fly, then somehow his truck will be able to fly too.
- In "German Guy", Peter and Chris end up in a hostage situation with an elderly Nazi named Franz. Chris disarms him and aims the gun...but can't tell who's Peter and who's Franz because they switched places (despite them looking absolutely nothing alike).
