** The introduction of the Legion of Super-Villains in ''Action Comics'' has Silver Age Lex displaying a fine example. He decides that since there exists a Legion of Super-Heroes there ''must'' exist a Legion of Super-Villains. Somehow. Of course, he's proven right moments later, because this is the Silver Age.

* In ''WesternAnimation/TheManyAdventuresOfWinnieThePooh'' Eyeore's explanation for how Piglet's house is Owl's house qualifies. But Pooh invokes this trope when he points out how they keep finding a sand pit when lost in the mist, which leads to him deducing that they should look for the pit instead to find their way home by accident. This leads to Rabbit deciding to prove this idea false, subverting the trope at first, only to double subvert it when it turns out that Pooh's plan is partially true; actively searching for the pit results in Rabbit not finding it, nor home.

* In Literature/TheQuran Abu Lahab doesn't believe and staunchly opposes UsefulNotes/TheProphetMuhammad -- to the point where the latter prophesies that Lahab will eventually burn in hellfire as an unbeliever. Of course, Lahab not believing in such things is unmoved by such a threat. The IST / Catch-22 comes when some use this passage to reason that Lahab could have easily have proven Muhammad's prophecy wrong and thereby scored further points by simply converting to Islam -- as it would thereby let him avoid going to hell (as according to Islam). Yes, Lahab ought to have debunked the teachings and inspiredness of Muhammad by accepting the teachings and inspiredness of Muhammad, according to the rules as dictated by teachings and inspiredness of Muhammad...

'''Gonzo:''' Sure, if you want to do it the ''easy'' way.[[note]]This, of course, would prove HilariousInHindsight, seeing as nowadays, Bombay makes even more movies than Hollywood does.[[/note]]

** The radio version also mentions that Marvin, the Paranoid Robot, who, due to copious amounts of time travel, ended up [[TimeAbyss several times older than the universe itself]], at long last finally broke down... and was promptly put back together again because his owners, i.e., Zaphod and the gang, were -- due to time travel -- alive at the time he broke, which of course went against the Sirius Cybernetics Corporation's lifetime warranty.

* In ''VisualNovel/UminekoWhenTheyCry'' this is what Battler's strategy degenerates into when he's desperately grasping at straws, no matter how ridiculous, as a viable theory (as long as magic isn't involved of course); from "spike-launching devices" to "small bombs". Beatrice lets the more amusing ones pass, at least for the time. Dlanor uses her laws to cut them down abruptly and mercilessly.

** This is also [[http://www.giantitp.com/comics/oots0206.html his reaction]] when Haley reverses the definitions of adventure and adventur''er'' to make him feel better. If anything they do counts as an adventure since they're adventurers, then of course he's going to go out and do the most random thing possible for the excitement that it's also an adventure. Even Miko is weirded out by his brand of Insane Troll Logic.

* This is part of the appeal of ''TabletopGame/{{Warhammer 40000}}'''s [[OurOrcsAreDifferent Orks]]. Imperial scholars theorize that somewhere in the distant past a Mekboy built two superficially identical vehicles, one of which was painted red. Due to an immeasurable internal difference, the red vehicle went faster, so the Orks decided it was due to the color scheme, a belief they've stuck with ever since. Since the Orks are unconsciously, latently psychic, this means that any vehicle painted red goes faster [[ClapYourHandsIfYouBelieve because they expect it to]].[[note]]It is entirely possible that Ork Mecs simply paint red those vehicles that are actually faster. Paint is not that expensive to not paint every vehicle in your army in desired color if it makes any difference. [[/note]]

* In the ''Recap/BigFinishDoctorWho'' spin-off audio "[[Recap/BigFinishDoctorWhoJennyTDDS2E4HerOwnWorstEnemy Her Own Worst Enemy]]" (looking at the adventures of Jenny, [[Recap/DoctorWhoS30E6TheDoctorsDaughter the Doctor's daughter]]), Jenny encounters a society that judges people by auditing them on whether ''they'' feel that they have lived a worthwhile life. As Jenny tries to point out, such a system doesn't actually work as the criteria being measured are too variable, as arrogant people will constantly justify their actions while good people may hold themselves to such a high standard that they can't live up to their own expectations.

** The same episode has a guy claiming aliens wanted him to be sentenced to death so they could save him at the last minute and prove their existence. Mari and Jasmine point out if the aliens were that powerful, they could easily find another way to prove they are real.

** The Auditors of Discworld reason that any sentient personality exists for a finite period, which is negligible in comparison to the infinity of Time. Therefore, they instantly cease to exist if they make the fatal mistake of identifying themselves as "I". The book Lampshades the Insane Troll Logic of this, but the erring Auditors themselves vanish too quickly to ever catch on.

* A SerialKiller (who specialized in [[BuriedAlive premature burial]]) in the ''Series/CriminalMinds'' novel ''Killer Profile'' claimed that, while he buried his victims, he was not responsible for their deaths, they alone were. They should have tried harder to escape, and because they did not, they obviously did not want to live and let themselves die, so all the alleged victims were not murdered, but actually committed suicide.

For examples of characters who engage in this, see TheDitz, {{Cloudcuckoolander}}, {{Straw|Character}}[[TheWarOnStraw men]], MoralGuardians, and of course trolls of both [[{{Troll}} internet]] and [[OurTrollsAreDifferent mythological]] origin. A character will tend to use this when [[KnowNothingKnowItAll he thinks he is smarter than he really is]]. See also BatDeduction (when the Insane Troll Logic is used to deduce something - correctly), RightForTheWrongReasons (same), BlueAndOrangeMorality (when the troll logic stems from an otherworldly bizarre moral compass), and RealityIsOutToLunch (when reality actually follows the troll logic). IrrationalHatred may have this as its basis, and ChewbaccaDefense is literally ''built'' of it. And then, sometimes it's just ObfuscatingStupidity or ObfuscatingInsanity in action. No relation to Music/InsaneClownPosse… [[WordSaladLyrics for the most part]].

'''Administrivia/NoRealLifeExamplesPlease''' Disagreements may cause flame wars. Those very flame wars will happen on this website if started, therefore Wiki/TVTropes' servers might catch on fire and may get damaged, and spread to the rest of the internet via the gravity of the situation. You cannot argue with this, it's legitimate fact-based physics. That's why it will happen physically. These flame wars will be the depth of the Internet — No, not DEATH, but they are similar concepts because they're similarly pronounced. Furthermore, many computers are connected to those servers and they might catch on fire, too. Because if you can see a fire, you can feel the heat. Ergo, fire is bad, and everyone needs to cool down a bit. [[SelfDemonstratingArticle So, remember to always douse your computer with water when having a disagreement.]]

** ''VisualNovel/Danganronpa2'': [[spoiler:Mikan tries arguing (very poorly) that her double murder of Ibuki and Hiyoko wasn't her fault because everyone else obviously hates her and they drove her to do what she did by making her into her current self with their bullying, so everyone should just immediately forgive her. Never mind the fact that sans from Hiyoko literally everyone else in the of the cast shows no hostility towards Mikan, and in fact, most of them have shown her the exact opposite. This is also a doubly awful excuse, as Hiyoko, the only person in ther whole cast who is shown bullying Mikan, and thus the only one Mikan might have some ounch of justified hostility towards, was only killed out of neccessity due to being a chance witness in Ibuki's killing. Ibuki, the most cheerful and friendly character bar none, never did anything to harm Mikan, despite being who she picks as her victim.]]
** ''VisualNovel/DanganronpaV3'': Himiko is the Ultimate Magician who prefers being called the Ultimate Mage, and acts like she can perform real magic. This leads to her often claiming that things happened as a result of magic. [[spoiler:Gets to ludicrious degrees during the second class trial, as the body was discovered during Himiko's magic show. The first portion of the trial is spent with Himiko refusing to drop the "it was genuine magic" shtick, even though it was ''making her the prime suspect''. After Shuichi proves how the trick was done she ''still'' insists it was real magic, and that she's not a magicain for the rest of the game.]]

* From ''{{Webcomic/Homestuck}}'':
** In one of the later chapters, Terezi attempts her hand at insane troll logic when she finds the [[spoiler:corpses of her recently murdered friends]]. According to Terezi, there is no way that it could be anyone but Vriska. To rule out any discrepancies in her logic, she fabricates her own story in which Vriska [[spoiler:murdered several trolls, then developed a taste for troll blood (which would explain the vampiric markings on the side of Feferi's neck)]]. She gives up on trying to explain it, acknowledging that her explanation is [[http://www.mspaintadventures.com/?s=6&p=005337 stupid and unlikely]]. However, this doesn't change her mind ''at all'' about the culprit, logic be damned. [[KnightTemplar She's not at her most sane by this point]].
** Post-scratch Derse apparently has its own version of Serious Business (a social network). [[http://www.mspaintadventures.com/?s=6&p=007469 The first time we see it]], a Dersite known as HATLIKER tells everyone that he accidentally sat on his favourite hat. What do the others suggest? Turning the hat upside-down and sit on it again to "unsit" on it.

* Havest from the ''ComicBook/New52'' almost certainly counts. In the future, he fought in a war against metahumans, which started when Superman retreated from the world after the gradual death of his son, Jon Lane Kent. When his own son dies in the war, the man who would become Harvest decides to end the war by any means necessary. How does he accomplish this? By going back in time, infecting little Jon with something that'll make him look like he died of a birth defect, kidnapping him when everyone thinks he's dead, and brings him back to the future to raise as his own son and anti-metahuman weapon. That's right, Harvest '''started the very war''' his son and countless others died in… all so he could ''end it''.

* ''Film/ThePrincessBride'': Vizzini batters the Man in Black with a series of contradicting logical deductions to decide which cup is poisoned. The Man in Black accuses him of using his monologue to trick him into revealing where the poison is. Whether this is his goal or not is never explicitly explained, since the core of Vizzini's trick is simply [[spoiler:switching goblets while the Man in Black's back is turned. It's unclear whether his deductions truly led him to believe that the goblet originally in front of him was the poisoned one, or whether he was simply counting on the Man in Black's reaction to his choice being the confirmation]]. Either way, he was wrong.[[note]]He was most likely just probing for a reaction-- if he were actually paying attention to his own logic, he might have realized that his alternating conclusions that "I can clearly not choose the wine in front of you," and "I can clearly not choose the wine in front of me," might ''both'' be correct.[[/note]]

* ''Webcomic/TheWhiteboard'': [[http://www.the-whiteboard.com/autotwb1154.html According to Doc]], he won't need a parachute when he next goes skydiving. He'll just bring along an extension cord or some welding leads, and [[MurphysLaw it's an even bet that they'll snag]] on ''something'' before he lands.

** Mr. Lamb asks his landlady Mrs. Bradby to charge less rent for the benefit of both of them. When Mildred questions how it brings help to her, Lamb says that in weeks he can't pay she loses less money.
