Interviewer : Once, there was an insane king, who wanted to test the intelligence of a young man. So he asked ” Oh young man! Tell me a sentence you like. If it is true, I will kill you by a sword. If your sentence is false, you’ll be hanged to death.”
If you were in the position of that young man, what would you do to save yourself?
Candidate : Sir, I would say “Oh my majesty! I would be hanged to death.”
Explanation : If the sentence said by the candidate is true, he should be killed by a sword according to the given conditions, but if the sentence itself is true, he should be hanged (by the literal meaning of the sentence). So the sentence is not true. But if it is false, he should be hanged to death according to the given conditions, but if the sentence itself is false, he should not be hanged to death (again by the literal meaning of the sentence). So the sentence is not false either. Hence, he got saved.
