A red parrot once said: "As long as my lie isn't solved, I will always lie."
In turn, a blue parrot said: "If the red parrot lies, the yellow parrot will also lie."
And the yellow parrot said: "Whoever is able of solving my lie will tell the truth."

What parrot is lying?

Oh, and feel free to share any other mind games/trick questions you might have.

The blue one. I tried to write down my reasoning but it has eluded me.

I actually didn't get the sayings. What do they mean by "solving my lie"?

Btw, I'd vote for Blanka!

Did I just wander into an obscure NES RPG?

Translating this Brazilian phrase was harder than the puzzle itself, but I think I get it. "Solve my lie" seems to mean being correct when commenting on whether or not a person is telling the truth. Blue is the only one commenting on their truthfulness, so Red is saying "If what blue says is correct, I am lying". Blue speaks proper English, so we just have to figure out Yellow, who I can interpret 2 ways. Either he's saying "The person who comments on whether or not I'm lying (Blue) is telling the truth", or, "If Blue is telling the truth about how I lie, Blue is telling the truth". So here's how how it goes for either one:

If what blue says is correct, I am lying
If red is lying, yellow is lying
If blue is telling the truth, Blue is telling the truth (I'm stating the self evident, thus telling the truth)

So yellow is telling the truth. That means that if Blue is telling the truth, Red can't be lying. Red says that if Blue is correct (which means Red is telling the truth) he is lying.
-If blue is telling the truth, Red just said "If I am telling the truth, I am lying." Red is lying. But that would mean that yellow is lying, which it isn't, so Blue would also be lying.
-If blue is lying, that means Red could be lying. If blue is lying, Red is saying that he isn't lying, which works.
Blue is lying.

The other interpretation

If what blue says is correct, I am lying
If red is lying, yellow is lying
Blue is telling the truth

Blue says that if Red is lying, yellow is lying about Blue telling the truth. So in order for blue to be telling the truth, Red must be telling the truth, which it can't be because it says if Blue is telling the truth he (Red) is lying. But if Blue is lying that means Yellow is lying. Therefore this interpretation must be wrong, or Cara is lying about there only being one parrot lying.

Either way, my brain hurts.

Or like “Labyrinth”, they are all cheating you…

Ok, I'll give: that enigma I threw at you was based on a little philosophical concept known as the Liar Paradox (and to a certain extent, on the Epimenides Paradox). In other words: when you try to find a solution to that question, you only find a continuous link of facts, that ultimately lead to no answer at all.

Or you could just ask the parrots if they were wearing glasses, but that goes against the rules.
Speaking of parrots: the original puzzle used a lawyer, a judge, and a whatever-word-you-have-for who's-on-trial-that-escapes-me-now, and was much harder to translate; so, I came up with color-coded birds.

Anyway, you guys seriously don't have any "brain exercises" to show off? Anything goes.

Er...how much wood could a woodchuck chuck if a woodchuck could chuck gophers?

(Just throwing crap out there, really...)

I think I got one, but I bearly remember it correctly. Still, I'll see if anyone can give this a shot:

Water drowns Fire, Fire burns Earth, Earth repells Wind, Wind parts Water. Water heals Earth, Earth fules Fire, Fire heats Wind, Wind guides Water. We all rule over each other, but what element rules all?

Hydrogen.

HEART.

edit: Green's is better.

Boobies.

Either Light, Darkness or Psychic.

EDIT: Meh, forget it. Gibbon owned the rest of us.

I'm selling these fine leather jackets

My name is Bobbin Threadbare and I'm looking for a flock of swans.

You make me want to puke.

Shut up. Loom is law.

You fail. Proper response was "You make me think somebody already did." Let's try this again.

There are no words for how disgusting you are.

Also <i>Loom</i> WAS awesome, although it totally needed to become the trilogy it was always planned to be.

How appropriate, you fight like a cow.

Yes there are. You just never learned them.

Every one of you fights like a dairy farmer.

I'd post Einstein's famous one, but I'm sure everyone knows that one already.

A girl, whom lives in a house, realises that she's out of milk. She turns off all the lights in her house and goes to a petrol station for milk. When she comes back, her house is destroyed.

How was the house destroyed?

Boat ran into it. She lives in a lighthouse.
