Answer to: Boiled or Fried

The thief said: "You will boil me in water." The King was faced with a dilemma. If he boiled the thief in water, that would make his statement true, which means he should have been fried in oil. They can only fry him in oil if he makes a true statement, but if they do, it would make his final statement false. The King had no way out of his situation and was forced to free the thief.
