Question: If a monster comes up to you and says, "If you tell the truth, I will strangle you, if you tell a lie I will chop your head off." What do you say?
Answer: You can either say, "You will chop my head off," or "you will strangle me." For example, if you say, "You will chop my head off." If he strangles you, that will make the statement false. The statement is now false, so he'll have to chop your head off, but if he does, that will make the statment true. Causing you to be free.
