Ladies And Gentlemen…Liars!
Riddle: A man and a woman are talking to each other. One of them is a brunette, while the other person is blond. The brunette says, "I'm a lady,". And the blond person says, "I'm a gentleman,". Assuming that at least one person is lying, can you guess who's who?
Answer: If we suppose that only one person is lying, then the people would either be both ladies or both gentlemen, which contradicts the first statement. Therefore, both people lied; the woman has blond hair, while the man had brunette hair.
