One Guard Always Lies & One Guard Always Tells The Truth 

I aaid it the perfect distraction 😂XDHAHAHA

"the goose"

What if he always lies?

it's like a parent throwing out a puzzle in a toddler's direction as a distraction before going back to the other parent to help finish making dinner quick enough before chaos ensues

I have the answer to both. Do something (hand a paper) to one of them and ask the other if you just did it. Take the goose first, take the fox, take the goose back, bring the seeds, come back and get the goose

The fact is he messed up, neither of them would ever say they are the lier.

I'd say it was pretty clear that was intentional, given the deliberation with which he said it. The only real question is whether Brennan started riffing of the intentionally wrong answer, or had fully expected that an internal argument was the funniest way to go.

I mean, it's all staged. They're on a stage.

​@@westrim well, ru-vid.comtLeAmByXvNs

@@jmackmcneillBrennan would immediately clock what he was saying was off, because the premise is either true or false as he’s saying it and that would cause confusion. Brennan set it up lol

“Well, I mean, the fork is metaphorical, it’s not, you know, like the thing you eat with. And, technically, yeah, sure, the labyrinth is a metaphor too. Honestly, don’t even get me started on that… what was I saying? Oh, right. Truthfully? You had the reward all along, it was the power of believing in yourself, you can just go home now.”

Or the whole premise is a lie and they're both liars.

I honestly think that's an even more clever way to solve the riddle than the traditional solution. The traditional solution being you ask guard 1 what type of guard (lying or truth telling) guard 2 would say guard 1 is. If the guard says "He would say I tell the truth", then that's the lying guard. If he says "He would say I lie", then that's the truth telling guard.

​@@consideringorthodoxy5495 that gives you the truth and liar identities but the classic puzzle gives you one question to ask to get the correct path. so the classic solution asks which path to take +the loopdeloop part of the question + you going the opposite direction.

@@consideringorthodoxy5495 The traditional solution is to ask one of the guards which way the other guard would tell you to go, and then go the opposite way. If you ask guard 1 what guard 2 would say and he says right, go left, because if guard 1 is lying, then it means he is lying about what guard 2 would say, and if guard 1 is telling the truth then he would tell you truthfully what guard 2 would say, so you go the opposite way.

Lol this is a really funny way it could have gone as well. Nice one

Extremely underrated comment

Jerry just won't forget or forgive.

Ah but is he sorry? Did he say it? He seems to always lie.

By explaining the premise, the first guard has shown he's the the one who tells the truth. Otherwise if he was the liar it would mean that the riddle wasn't explained properly and so you couldn't trust the entire premise ruining the whole point of the riddle.

I am really glad that someone finally pointed that out.

What if he IS lying and the river could be crossed without any of those things?

The best part is they could *both* be liars

It doesnt really. Their both supposed to say that the other is the liar.

​@@biz09ificationhim explaining truthfully breaks it, as he didn't lie, so the other one is a liar

Technically, no, that would be terrible advice for most things.

It's brilliant riddle writing advice

@@catastropheoverclock True

I love how every single part of this skit was programming riddles given to CS freshmen.

But, but which one??!! 😭😂

@@ashofmeal9453obviously Brennan was telling the truth. He gave it away with his starting schpiel; if he was the liar, none of it would’ve been true.

Plot twist the guard that declared the premise is the liar and they both lie in reality.

Or was he? *vsauce music*

Well if he was the liar, he coudn't say so. But if he told the truth, he couldn't say he was the liar. In both cases he break rules he supposedly can't break, so from this point the only option is that the guard who declared the premise is lying on the rules.

goose and fox are alone though on the other side while you get the grain.

@@RuneKatashima no cus I immediately take the goose back across

Or, alternatively: take the goose across. Go back empty. Take the grain across. Leave the fox, why do you have a fox? This version brought to you by XKCD.

@@Fre_shAvocadoYeah, I can’t see any flaws in that, personally. Good job! /Gen

My favorite solution is “Are you a tree frog?”

@@foudesfilms Omg that’s genius!

I think they shared the line in the original.

"One of us speaks in riddles, the other speaks in rhymes!"

​@@joshuafox8856if they say the same thing, how are they still keeping the "always lies/always truth" premise? I've seen it where there's like, a sign (plaque?) explaining it which seems to work best I think.

@@3possumsinatrenchcoat they each speak one word of the sentence. So in effect neither one said the premise but it was said.

Unless the puzzle itself is a lie.

Unless they are both liars. If they are both liars, the setup of the premise is a liar (because both are liars in stead of only one being a liar). And saying I am thr liar is a lie, both it implies the other speaks the truth, when in fact both are liars. My head hurts...

Yes, Brennan is always lying, so his exposition of the premise also *has* to be untrue.

But the premise exists outside the power of the skit to an extent, so while two liars can work, it assumes that the prompt is equal to the characters when in fact the prompt is a hyperversal entity which created them.

Not necessarily. If Brennan's guard is the liar, then the whole premise is a lie to begin with.

​@@josephperez2004that was the brother paradox answer in yugioh.

I thought it already broke from the moment Brennan explained the premise. Wouldn't that mean he was telling the truth?

@@SpyrosKoronis But saying "I am" is a paradox. By saying he is the liar, it's a truth, which then makes it false meaning it's a lie, and so on and so forth.

@@SpyrosKoronis It exposed him as the one who tells the truth (unless he snuck some lie in somewhere). Ross saying “I am” breaks it because _neither_ should ever answer that question positively.

I suppose I should have been clearer. I meant "broke" as in "made moot", not as in "created a paradox", although both cases invalidate the premise.

@@SpyrosKoronis There is a logic in both. If Brennan rules applied, he was the truth-teller anyway. But Ross doesn't create an impossible situation with his response either. It just means that the rules explained by Brennan don't apply, that he lied and there are in fact other rules. My speculation so far is a Limbo contest.

*which

it’s accidentally the best way this could have gone it’s so funny

1+1=2 "Correct" - Guard 1 "Wrong" -Chad Guard 2

The correct answer was “Not me”

1000th like! Your welcome bro

My ADHD ass 10/10 would've said it just as confidently. Brain was faster than his mouth lol

The famous Liar Paradox..... 😂😂😂

Thats partly how you solve it

He actually fucked up because if he always lies then he shouldn't have said he was the liar and if he always tells the truth then it is incorrect to call himself the liar. Basically he should've said "I'm not" and then he could be both lying and telling the truth making the question useless. He fucked up.

@@TheEtherny Or the first guard had to answer that question. Having the second guard definitively answer that question either way validates the original claim.

​@@TheEthernythey sed he was a liar, not that he can only lie, you only need to lie once to be a liar, and it doesn't even have to be in your conversation. He might not even be a gard, but an imposter. Now there's a plot twist 😂

Unless he lied.

@@TheBenFlock A liar wouldn't appear accurate, so no.

Or "He is."

That is correct. Although with Brennan explaining the rules first, which are previously given as truth, he can already be identified as the truth speaking guard.. great improv nonetheless

"One guard always speaks true, the other in paradox. Our liar called in sick."

​@@earthgameplot twist: they're both liars

@@earthgameactually, he could have been the “lying guard” in that they don’t actually only speak in truth/lies

What makes it funnier is that that's one of the questions that won't solve the issue: the liar will lie and say the other guard is lying. And the one that tellls the truth will also say the other one is lying, which is true.

​@@gauchofromhell Unless the liar forgets they're not supposed to be honest about their lying 😂

Yup....since one of them could only tell the truth and couldn't lie, if one of them admitted to being the liar then they had to in fact be the liar. If he had said "not me" instead then the game would still be on.

@@gauchofromhellWait. So there wouldn’t be a time where either would answer that question with “I am”? That makes it even better

@@gauchofromhell Both guards can respond that the other is the liar, but the liar can't say he is the liar, otherwise he tells the truth. So he broke the rules, and in this situation the only explanation (beyond comedy ofc) is the one who explained the rules lied.

That was always my interpretation of the answer - that they both lie. To say that one always lies is a lie, since they both lie. And to say one always tells the truth is also a lie. So no matter which of them is saying the statement, they’re both technically correct in their lies.

That and the part where they realize they can just stab him.

Ikr, just the fact that he explains the whole thing makes him the one who is doomed to say the truth, but then saying “I am a liar” questions even the idea that this is the true trope-

@@m9l0m6nmelkior7"lier" 😂😂

It's not necessarily a fuck up. With those two statements we don't know anything about the guards yet. It could be that the first guard always lies, and the second guard chooses answers at random.

@@Hahahahaaahaahaa Yea, well, by that logic they could both be liars or maybe just two dudes with nothing special about them whatsoever. The point is that they fucked up the puzzle.

I actually remember the solution of that puzzle, first you take the Goose, as the Fox and the Grain can be together, Then you bring over the Grain and take back the goose, switch the Goose with the Fox, take the Fox over, and finally go back empty to pick up the goose

⁠@@Voron_Aggrav am I misremembering or was that puzzle in a poptropica game because Im getting 'looked up a walkthrough for this in elementary school' dejavu 😂

@@anny8720 I don't know, but both of them are very old, probably even older than computers

it’s actually amazing that he nailed the explanation on the spot so quickly. I don’t think it’s fully appreciated how hard that is, it’s like doing math on live TV/stream. No matter how simple it will scramble your brain unless you’re very good

Ask them both if one’s a liar and one honest If they give the same answer there both liars If one saids there both honest or lairs then the first one is telling the truth

The liar would point at the guard telling the truth and say he’s the liar and the guard telling the truth would point at the liar and tell the truth saying he’s the liar so they both would point at each other no?

​@diegopulido2528 Exactly, which is why saying 'I am' breaks the entire setup, because the Liar wouldn't declare themselves the liar, and the truther can't say he himself lies Simply put they both fucked it up

Wouldn't lying about the premise be impossible? I don't know of a way in which the premise could be presented by either of the guards without indicating who is who. Every time I've seen this, it's an unseen narrator setting it up 🤔

He said "you've arrived at a fork in the path on your way to the center of the labyrinth". If it's true, he says the truth, the rules are correct, and the answer is pretty easy. If the guard says "I see you flying on a winged pig on your way home to the castle of your cousin and very good friend Dracula the gerbil" and it's not true, he lies.

😂😂😂

The truth of the matter: one guard tells only lies, and the other guard tells only paradoxes.

Assuming the premise Brennan said was true, It would work if Ross said Brennan was the liar [a lie] and Brennan said Ross was the liar [the truth].

​@noodle3218 yes, thank you. He could accuse Brennan of saying that he is a liar, of course, to gain the traveler's trust and send them down the wrong path, which Brennan would then accuse him of doing also because he is honest but it would be hard for a stranger to know who is truly honest without asking further questions

Exactly. The truth-teller would be forced to point out that the other is a liar, and the liar would of course not implicate himself.

They could also just decline to answer too, since silence (even though it speaks volumes) doesn’t speak the true or false answer

Just ask what 1+1 is

@@HuskerHornet3145 Or they could skip the riddle altogether and just stab the guy. But neither seem very sporting, do they?

​@@case425that doesn't solve the actual riddle though. The idea is that they are guarding two doors/paths. One leads to certain death, one leads to success/freedom. You only get one question to find the correct path. If you use that question to determine which one the liar is, you still don't know which path to take. I believe the correct answer to the riddle is "what path would your partner tell me is correct?". They both will say the same thing.

​@@HuskerHornet3145I think they're explaining why the guards should not have answered with "I Am!" at least. Via the rules of their game, they should answer, but they got tricked into breaking their own rules.

They would both deny being the liar.

It is “who would your brother say is a liar.” the truth teller would answer “he would call me the lair”. the liar would answer with that his brother would call Himself the liar

Not really. Their both supposed to declair that the other is the liar or that they themselves is telling the truth

@@biz09ification The guard who said "I am" created the paradox

​@@biz09ificationthe joke is that the puzzle is so confusing even the guards administrating it are confused

No, they both say “I am” problem solved

@@xPRIMExNITROx no the paradox is the liar must lie, so if asked "which one is the liar" he can't admit to being the liar. The liar would have to say his partner is the liar.

The question wasn't tricky, the answer was 😂

And here's the answer to the other puzzle: 1. Take the goose across 2. Return alone 3. Take the grain across 4. Leave the fox (why did you have a fox)?

Low key, best comment

Guard1: "Liar"

Guard 1: One of us always tells the truth. The other always lies!" Guard 2: "He's right, you know!"

Underrated comment 😂

The only way this works is when both lie.

"Diversionary riddel" is too funny

First take the goose across, then go back and bring the grain across, and then leave. Why did you have a wild animal?

​@@DaxylStuff the fox in the grain bag to guard it from the goose, then tie it shut so it can't get out.

They could both be liars.

Wjhat do you mean?

@@fishyfish1917 Okay so Ross is clearly supposed to be the guard that lies, right? That means anything he says has to be false. Since he poses the fox-goose-grain puzzle, he would have to have told it wrong in some way - such as the fox _can_ be left alone with the goose. Since he tells it exactly how the puzzle is meant to be told, he's telling the truth again which is not his role in the Truth Guard/Lie Guard puzzle.

Wouldn't the answer to that puzzle just leave the fox with the grain?

@@LoRosa0224 right but you’d have to come back for the fox or the grain after, but if you leave either one on the other side with the goose, something will get eaten. The answer is 1) take the goose over, return with nothing 2) take the fox to the other side, return with the goose 3) take the grain over, return with nothing 4) bring the goose to the other side

The guy who set up the premise is lying. They both can lie whenever they so choose

They could both be liars.

They could both be liars.

So the solution is to pull up a quest helper?

@liger04 goose across. Fox across. Goose back. Grain across. Goose across. Solved. The puzzle is that if the Grain and Goose or the fox and the Goose are together when you take something across the bridge, the Goose will eat the Grain or the fox will eat the Goose. (Usually its a chicken, not a goose).

Dam temple nights xp

@@ToughBreK3 The second thing to be taken across can be either the fox _or_ the grain. The important takeaway from the setup is simply that the goose cannot be left unattended with anything else.

​@@coryzilligen790damn geese! Absolutely zero accountability!!

The second guard was a programmer and had a bug dealing with strings rather than ints.

If he’d specified the rules correctly, you have one question that can only be asked to one of the guards, problem solved. The other problem, “After this announcement, only then can one guard only speak true and the other lie.” Doesn’t take a genius to get it right, the answer’s a little more complicated, but I know it.

@AndrewHalliwell So, the way our DM did it, he said "Each of you is permitted to ask one question" there were four of us, so he was probably trying to make sure all of us could contribute, he just (for whatever reason) assumed that my bard, who's go-to move for the entire game was vicious mockery, wouldn't be a smart-ass in this one instance.

I mean, that's not really being a smartass that's just solving the riddle. What did the DM think was gonna happen?

@proton8239 in his defense, we absolutely botched a puzzle earlier mostly because someone in our group cant tell the difference between radius and diameter, so I don't blame him for simplifying it. But according to the DM, he figured we would ask questions specific to the dungeon or to the guardians to narrow down who was telling the truth. He just overlooked the fact that stupidly simple questions could break the puzzle. But, honestly, who cares? We laughed our asses off and have a funny story to tell, so who cares if we did the puzzle correctly.

This is the second comment I've seen along these lines, is it a reference?

​@EzaleaGraves I believe it's a reference to another game changer episode?? I have a vague memory of seeing this exact bit as another short

Ok that was a clever twist😂

Thank you I love this! I will absolutely use this as a Barbarian one day I’m sure.

Barbarian kills one of them, asks the other „He dead? G-„No“ B-„This one liar“

Okay, the original version on this is that you only get one question, though, so you just used that up.

​@@jenikabartlett9396they used it up on getting the right answer though

The rest of the skit is Ross telling Brennan to not reveal so much info so that the logic puzzle could be bypassed.

He could be referring to cutlery, it could still be a lie.

I’m pretty sure the scene in Labyrinth also played out similarly. I haven’t watched in a decade but they had a bit of an argument.

thing is, "he is" is just as broken: you answer with that, but if you're the liar, then you're lying, pointing at the other one. if you're not the liar, you're telling the truth. Neither can answer 'I am' and follow the logical problem of the 'always' part of 'lie/tell the truth'. the trick is that the one faced with the conundrum needs to ask a question were no matter who answers, the answer itself reveals the liar. I don't remember what the puzzles' actual "question-answer" is tho.

@@AlMcpherson79 You could just ask each of them how many guards guard the pathway

​@@AlMcpherson79the answer is always to ask either guard which path the OTHER guard would tell you is correct, then take the opposite path. either you're speaking to the liar who is lying about which path the truther would point you towards, or you're speaking to the truther who is correctly telling you which path the liar would mislead you with.

You could just like ask what color an orange is, if he answers orange, he's the truth teller. If he answers anything else, he's the liar.

​@@steveoconnivo9666 don't oranges start start out green and then ripen to orange?

Yes! The only logical conclusion to "I am the liar" is that he does lie but not right now. So the premise was clearly a lie. But we can't know if the first guard also can tell the truth, so getting any valuable information from them is impossible.

I like how for a moment the liar forgot to lie and admitted he played the role of a liar.

but if both guards sometimes lie and sometimes tell the truth... 😈

What if it's not the center of a labyrinth, though? Then they lied

Its called the Liar Paradox 😂

Unless he's the liar and he changed a rule of the game.

Or they're both liars

Thanks for this comment! Other folks seem to be forgetting that the actual CRUX of the problem, if the setup is done *properly* is that you only have the ONE question to discern the liar from the truth-teller, and no *second* question in which to ask for the actual directions. 😋😋

im glad somebody else gets this one

Omg I had to visualise your comment, I get it now. Thank you!!

if he's not telling the truth, then maybe both of them are liars since he's the one who stated that there's one lying and one telling the truth.

@fliptheflipped or one always lies, and the other can either lie or tell the truth

If Brenna is the liar this whole thing is fucked

​@@fliptheflipped He could also just be lying for fun. I'm pretty sure if the one saying the prompt isn't telling the truth, there's no way to solve the puzzle, other than asking the same question forever until one of them cracks.

It may Seem the path is straightforward, but a keen eye will notice, half buried in the dirt, there is Indeed a Fork and therefore, he is the truth teller

Thank you! Everyone is commenting on the liar paradox but whenever I hear the boat animal riddle, I am stumped

I knew you had to do a Bring Something Back thing, ty!!! Scrolled for your comment.

The real answer is that you eat the goose, then bring the fox and grain over before it digests fully.

I found "how to beat the Labyrinth" and the guards puzzle is beatable with this rule - you get to ask one guard one question. The question you should ask is, what will the other guard say is the safe fork in the path? If Path A is safe and Path B is unsafe, the lying guard will say that the other guard recommends Path B (he thinks you'll spot the lie.) The truthful guard, asked the same question, will say that the other guard lies and will recommend Path B (he also thinks you'll spot the lie.) The solution is to always choose Path A or the opposite of what either guard says.

I think another point at that scene is that it's taken for granted that any of the guards would be telling the truth.

The guards immediately frame Sarah's perception of them and the situation she is in.

@@ALTR.555 I want to make sure everyone understands the point here. If you consider that, while the guards are explaining the situation here, one of them is presumably lying, because he has to. This totally changes the challenge she faces.
