here is a favorite of mine

You are rushing your mother to the hospital

There is a fork in the road and you dont remember which way to go

There are two twin brothers there, one who always lies and one who always tells the truth. They look identical, and it is impossible to tell them apart

You only have time to ask one brother one question. And again, the one who answers you have no idea if he is the one who lies or tells the truth

What one question can you ask so that no matter which brother answers, you will know which way to go to save your mother

Answer: <font color="white"> "If I asked your brother which way is it to the hospital, what would he say?" Then go in the other direction. </font>

[/ QUOTE ] Or:<font color="white"> There is an alternative answer. Ask one of them "If I were to ask you which way to go, what would you say?" Then go the way he says. </font>

well the liar will say the wrong way but the truthteller will tell you the right way....effective....

[/ QUOTE ]

What? The truthteller will obviously tell you the right way, but so will the liar. The liar knows he would tell you the wrong answer to the question "Which is the right way?" so when you ask him "If I were to ask which way is the right way, what would you tell me?" he would have to lie about his answer, so he tells you the correct way.

I thought you were mistaken, but after reading this a couple times, it works. Just watched Labyrinth yesterday, had to chime in for no good reason.
