⟩ A man suspected his wife of having an affair. One day he told her that he had been suddenly called away on business and would be out of town for a few days. He then left the house but returned an hour later. His wife was not there but he quickly discovered the name and address of her lover. How?
He reasoned that she would have called her lover so he simply pressed the redial button on their telephone. When the man answered with his name the husband told him that he had won a prize draw and asked for the address to which it should be sent.
