    A man and A women

    A man and a woman were the only two people walking along a beach. "I'm a man," said the one with the black hair. "I'm a women," said the one with the red hair. At least one of them was lying. What was the color of the woman's hair?

    The woman has black hair.

    How do I know this? Well you know there is a man and a woman. You also know that at least one of them is lying.

    That means that if the one with black hair is a lier than it's a woman, but that would mean the red haired one is a man.

    What if the red-haired one was lying, that means that he's a man, which means that the other one must be a woman.

    In both cases, the one with black hair is the woman.

    Which means they're both lying.
