One day the King decided that he would force all his subjects to tell the truth. A gallows was erected in front of the city gates. A herald announced, "Whoever would enter the city must first answer the truth to a question which will be put to him." Nasrudin was first in line. The captain of the guard asked him, "Where are you going? Tell the truth -- the alternative is death by hanging." "I am going," said Nasrudin, "to be hanged on that gallows." "I don't believe you." "Very well, if I have told a lie, then hang me!" "But that would make it the truth!" "Exactly," said Nasrudin, "your truth."
