Yet another good one.
You are a prisoner in a room with two doors. You must pick a door to go out of. One leads to freedom, one leads to a firing squad. There are two guards in the room. One of them always lies, one of them always tells the truth. You do not know which is which. You get to ask ONE question and ONE question only. Can you get out of the room with your life?
