A man is fighting with a cup of coffee. The rules: he must not br break the cup nor spill its coffee; nor must the cup break the br man's bones or spill his blood. br br The man said, oh the hell with it, as he swept the cup to br the floor. The cup did not break but its coffee poured out br of its open self. br br The cup cried, don't hurt me, please don't hurt me; I am br without mobility, I have no defense save my utility; use br me to hold your coffee.
