Oh! what a tangled web we weave

When first we practise to deceive!
Walter Scott, Marmion (Canto VI. Stanza 17)

A suspicious character, thinking a friend or loved one is lying, goes along with the lie, forcing the liar to expand upon the cover story in a grossly outlandish fashion. Named for "pull the thread, and watch the sweater unravel."

In a comedy series, this can result in a Fawlty Towers Plot situation. In a drama, it results in the catastrophic collapse of a villain's house-of-cards scheme. May result from Spotting the Thread. Not to be confused with All Cloth Unravels, when literally pulling a single loose thread on a piece of clothing causes the whole piece of clothing to come undone.

Contrast Seamless Spontaneous Lie.

Examples of Pull the Thread include:

Anime and Manga


  • The film Shattered Glass has editor Charles Lane asking reporter Stephen Glass to retrace a sequence of events reported in one of the latter's (completely made-up) news articles. Glass picks a building and a restaurant more or less at random, then has the spectacularly bad luck of discovering both were closed at the time the events in his article supposedly took place. The trope is eventually subverted because no matter how many blatant lies Lane catches him in, Glass never capitulates and continues to spin how it could have happened (supposedly it happened this way in real life as well).
  • The ending of the 1974 version of The Taking of Pelham 123 has the last remaining hijacker accidentally giving away his identity with his recognizable sneeze.


  • Recall the elegant subversion in To Kill a Mockingbird: Atticus successfully pulls many threads in the Ewells' story of how Tom raped Mayella, particularly in the disparity of Mayella's bruise and Tom's handicap but the all-white jury ends up finding him guilty anyway.
  • In Lois McMaster Bujold's Vorkosigan Saga novel The Warrior's Apprentice, Miles invents the "Dendarii Free Mercenaries" out of whole cloth as a quick cover story. Then the new "provisonal members" start to inadvertently Pull the Thread , so he adds more detail. By the end of the novel there actually IS a Dendarii Free Mercenaries, uniform, field manual, hidden government backing, and all. The majority of it essentially made up on the spot by 3 terribly overworked people.

Live Action TV

  • The usual tactic used on the BBC panel show Would I Lie to You, where the panelists present facts about either themselves or other famous people/events and the other team has to guess if they're telling the truth. Most lies collapse when the liars are pushed for information they haven't invented and contradict themselves. That said, being confused or vague doesn't always mean they're lying...
  • Every last Columbo episode revolves around Lt. Columbo pulling the threads in the culprit's story.
  • In all three incarnations of the CSI franchise, characters will indicate that it is time to Pull the Thread by saying, "Little lie, big lie."
  • The usual first step in The Perry Mason Method on Perry Mason.
  • Repeatedly inverted on Law & Order: Special Victims Unit: Any sociopathic criminal the detectives try this tactic on is so cunning, confident, and prepared, no matter how complex the cover story gets, it never collapses.
  • In Seinfeld, George's desperation not to spend time with his once-potential parents-in-law at a function they have arranged sees him concoct a story about owning a luxurious house in the Hamptons which he is spending time at, and ends with him driving them all the way to the Hamptons to keep the lie going. When he breaks down and admits the truth, they confirm they knew all along, but let him suffer through keeping up the charade because they don't like him very much.
  • Everybody Loves Raymond: Ray lies to cover up the fact that he didn't want to have dinner with his mother, Marie. To keep up the lie, he arranges a cover story with his wife. It snowballs until he ends up breaking the VCR and the washing machine, but she figures it out anyway when they run out of lies. Hilariously, Robert's wife Amy confesses to not eating the dinner Marie made them after watching her pull the thread and guilt-trip Ray, because "it's only a matter of time". Then a verbal slip from Marie reveals to Robert that she didn't actually make a special meal for him, she made it for Ray.
  • Used on Friends to get Chandler to admit he is in a relationship with Monica by having Phoebe come on to him.
    • Also, Monica warns Chandler against a similar danger when he sees a photograph of himself making his "bedroom eyes":

 Chandler: Oh my God! Those are my bedroom eyes?! Why did you ever sleep with me?

Monica: Do you really want to pull at that thread?

  • In Lost, Sayid interrogates a captive who claims to have reached the island by balloon. How big was the balloon? How did he afford it? What was the business he sold?
    • Except the captive answers all the questions in a self-consistent manner. Sayid thinks that he's probably lying, but can't tell for certain. He turns out to be the leader of the Others, Benjamin Linus.
  • Emily can't stop herself from pulling the thread in her S4 episode of Skins; it starts with Naomi telling one small lie to the police and ends in The Reveal that Naomi cheated on her at a university open day.
  • Lie to Me: This is half the premise.
  • How I Met Your Mother: One episode featured Robin revealing that she had an unusual fear of going to the mall. The other members of the group form theories as to why this is. Marshall believes it's because she got married at a mall when she lived in Canada. Not wanting to reveal the real reason, Robin decides to use this as her cover story. Ted decides to test her on it and asks her numerous detailed questions about her wedding, all of which Robin easily answers, but then blows it when she's suddenly unable to think of an answer when Ted asks her the simplest question, what the groom's name was.
    • The implication seems to be that like a lot of (mainly female) people, Robin has a pretty solid plan of what she wants her wedding to look like, with just a couple of details to be filled into the blanks.
    • Robin does this again when she tells them that they were right in thinking that she slept with a rather dumb guy after a Halloween party and thus did not have time to change out of her costume before the next morning. When the lie unravels we find out that she was still in her nurse uniform costume because it was actually for an adult diaper commercial she filmed.
  • Narrowly averted on Raising Hope after Victoria tells her cousin Delilah that Maw Maw has died just so Delilah would not come for a visit and see what a mess Victoria's life was. A few years later Delilah comes to town to see if Maw Maw left her anything in her will and Victoria starts spinning more lies to hide the truth. Delilah never finds out the truth because she is more interested in screwing with Victoria than pulling more threads. When she actually sees Maw Maw alive and walking she assumes it is a ghost come to punish her for being such a Jerkass.
  • It's pretty clear that Britta in the Community pilot has caught early on exactly what kind of guy Jeff really is, but is stringing him along until he can demonstrate it in front of everyone.
  • Pulling the thread on It's Always Sunny in Philadelphia leads to Frank and Dee (father and daughter mind you) almost getting married just to keep up the lie that they were in a relationship in order to scam some money.
  • The Doctor in Doctor Who loves doing this. In "Amy's Choice," he sums up his mission (and life philosophy) in two sentences: "Something's not right here. Let's go poke it with a stick..."


Tabletop Games

  • This is one of the rules of the storytelling game The Adventures of Baron Munchausen. One player starts to tell the most outlandish story about his adventures (Such as the time a pair of Frenchmen took credit for his invention of the hot air balloon), and the other players repeatedly interrupt him with additional questions. The storyteller has to either incorporate them into the story or pass the turn to the next player.
    • This player has a nice way of countering this. If another player gets a bit too vicious in picking your story apart, simply ask them "Are you implying that I would be lying, sirrah?". If they don't retract this implication, challenge them to a duel at dawn.
      • In the drinking version of the game, you are allowed to insult the questioner instead of actually answering their questions, as long as the insult is appropriately creative. However, you have to take a drink if you choose this option.


  • Oh, Oedipus, you just had to pull the thread yourself.

Video Games

  • Pulling the thread is an integral concept in the Ace Attorney series.
    • Well, usually. In most cases, it's not a matter of playing along with the lie, but with catching the lie and then forcing the person you're questioning into making up a lie to cover up the lie ("No, wait! I was mistaken!"). In at least one case (Mr. Kudo), this actually comes back to bite Phoenix, when he really should have convinced the court to listen to the person he just completely discredited.
    • This is essentially the point of the "press" option: if you can't see anything contradictory in the witnesses' current statement, you can ask them to elaborate, which quite often leads to them saying something that is contradictory, which you can then call them on.
  • During the Clear My Name quest of Neverwinter Nights, Chapter 2 you come across a "witness" who is obviously falsifying his story. Only by pulling the thread of his story can you get him to admit he was nowhere near the scene of the murder.
  • In Dragon Age, there is more than one way to reveal the fake Weylon. One, you just get too near a certain door and refuse to leave. The other is tricking him, intimidating him and forcing him to expand on his story while picking out all the mistakes he makes until he finally merely gets irritated and attacks.
  • In Clannad, pulling the thread on one of Sunohara's lies leads from how Sunohara's parents will get worried if they're out too late to the invention of an illegitimate adult son for the 23 year old Sagara Misae. Said son is named Sagara Missile. And to make things worse, Sunohara then nicknames Tomoya Apache and Tomoyo The Ultimate Weapon. But it works out okay because they still go and do what he wanted.
  • In the 1st Degree goes into this trope when it comes to questioning the witnesses.

Western Animation

  • Turned up in an episode of Cyberchase; The Hacker is running for president of Cyberspace, on the platform of "I'll cure Motherboard of that nasty virus I gave her" and mentions that doing so involves a triangle, which can be made with any three lines. When the Power Trio proves that not all lines can form (closed)triangles, everyone immediately stops believing Hacker and agrees with the kids. Kicking reason to curb indeed.
    • Fridge Brilliance. The whole show is based on math and logic, and in logical proofs refuting a single argument makes the whole thing invalid.
    • It's also justified in that the three lines he brought to form the triangle to cure Motherboard's virus were actually impossible to make a triangle with, so he really was lying the whole time and had no intention of curing her.

Real Life

  • Miss Manners actually recommended this tactic for dealing with a woman who always has to top whatever story you tell. If you say your wife just had a baby and she brings up a relative who just had triplets, Miss Manners advocates playing along with fervor: "Oh, how wonderful! When were they born? What are their names? How big were they? Did they have any medical problems? I hear triplets can be low birth-weight and need a respirator for a few weeks..." etc. Until she runs out of ammo, or realizes what you're doing, at least you're having as much fun with it as she is.
  • This is a common cross-examination technique. In most Western legal systems, lawyers aren't allowed to directly accuse a witness of lying as a challenge. The solution is to pull the thread until an inconsistency, either with evidence or prior statements, comes out. This can then be waved about, usually discrediting the witness in the eyes of the jury.

    Also a common police interrogation technique. Many confessions have come after the interrogator first gets the suspect to admit to a small lie ("Yeah, okay, I did know him") and then going from there.
    • Unfortunately, it's just as easy to get an innocent person to confess with this method as it is a guilty person.
  • Socrates did this with style and to some people he probably shouldn't have screwed with, although in his opinion it was his duty to do so, and he insisted that he really just wanted to learn instead of just being a dick. The Socratic method owes its name to his rhetoric. It should be noted that Socrates wasn't uncovering lies per se, but hypocrisies. And that he ended up highly dead.
  • Louis CK's stand-up routine about kids asking "why?" and how you should understand when their parents tell them to shut up, because "they just keep coming, more questions, why, why, why, until you don't even now who the fuck you are anymore at the end of the conversation!"

"Papa, why can't we go outside?"

"'Cause it's raining."


"Well, water's coming out of the sky."


"'Cause it was in a cloud."


"Well, clouds form... when there's... vapor."


"...I don't know! I don't know. I don't know any more things. Those are all the things I know."


"'Cause I'm stupid. Okay? I'm stupid."


"Well, 'cause I didn't pay attention in school, okay? I went to school but I didn't listen in class."


"'Cause I was high all the time! I smoked too much pot!"


"'Cause my parents gave me no guidance! They didn't give a shit!"


"'Cause they fucked in a car and had me, and they resented me for taking their youth!"


"Because they had bad morals! They had no compass!"


"'Cause they had shitty parents! It just keeps going back like that!"


"'Cause, fuck it, we're alone in the universe!..."

  • In mathematics and logic, there is proof by contradiction—one way of proving something is to assume the opposite is true, and follow the consequent trail of reasoning until you arrive at an obvious fallacy. For instance, one can reason that 1 = 2, but only if somewhere along the way they divide by zero. Since you end up with a contradiction, this shows that the original premise (that the opposite of what you wanted to prove was true) was actually false, and hence what you wanted to prove is true.
