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?
Answer: Either man should be asked the following question: "If I were to ask him if this is the way I should go, would he say yes?" While asking the question, the hiker should be pointing at either of the directions going from the fork.

Question: A cop was walking past a restaurant when he heard someone scream - "No John, not the gun!" He ran inside and and saw a doctor, a lawyer, a milkman, and a dead body on the floor. He promptly walked over to the milkman and arrested him. He didn't witness the shooting and there was no apparent evidence to prove who shot the person and no one told him who the killer was.
How did the policeman instantly know it was the milkman?
Answer: The milkman was the only male. The doctor and lawyer were females, so the cop knew that "John" was the milkman.
Question: We are a pair,
We can dart here and there,
Though we always stay in one place.
We can smile or shed tears,
Show our pleasure or fears,
And you'll find us on everyone's face.
What are we?
