    A judge was working in his room one day when a neighbour ran in and said, If one man's cow kills

another's, is the owner of the first cow responsible?

    It depends, answered the judge. Well, said the man, your cow has killed mine.

    Oh, answered the judge. Everyone knows that a cow cannot think like a man, so a cow is not responsible,

and that means that its owner is not responsible either.

    I am sorry, Judge, said the man. I made a mistake. I meant that my cow killed yours.
