Too bad for you that they electrocute you for being so cunning! If you say "You will hang me." , then you are creating a paradox - if they say it is a lie, then they will hang you, making it a truth. If they say it is true, they will shoot you, making it a lie.

Imagine you say, "You will hang me." It cannot be a truth, because then they will shoot you. But then what you said would be a lie. Contradiction. It cannot be a lie, because then they would hang you. But then what you said would be a truth. Contradiction. Therefore, the statement "You will hang me" is neither a truth or a lie, in this scenario.
