A hiker comes to a fork in the road and doesn't know which way to go to reach his destination. There are two men at the fork, one of whom always tells the truth while the other always lies. The hiker doesn't know which is which, though. He may ask one of the men only one question to find his way. Which man does he ask, and what is the question?

You can ask them only one question. Except! One lies and one tells the truth, and you don't know which is which. So, What do you ask?
