Two logicians are on holiday in the Alps when a mad scientist captures them. The mad scientist knocks them unconscious and then tattoos their forheads. When they awake, the mad scientist says with a sneer:
" At least one of your has a tattoo on your forehead. Maybe both of you do...I'm not telling. I will allow you to go free if you have a tattoo on your forehead. All you have to do is walk out that door.
However, if your walk out that door and you do not have a tattoo on your forehead, I will put you to to death. I will leave you in this room, and if you communicate with one another in any way, you will be put to death.
Every day at noon, I will have the door unlocked briefly. You can choose to leave then and only then if you think you have a tattoo on your forehead."
