Actually, one that I'm not sure what the proper answer is the one that says:

Two people stand at the parting of a Y fork. One is a compulsive liar, the other will only say the truth. You are trying to reach the city at the end of one of these forks, you may only ask one question to learn which path is the correct one to take
