If I had a hammer

A man is in court for murder and the judge says
"You are charged with beating your wife to death
with a hammer."
Then a voice at the back of the court says, "you
bastard."
Then the judge continues, "you are also charged
With beating Your daughter to death with a
hammer."
Again the voice at the back of the court says,
"you bastard."
The judge says, "now we cannot have any more of
these outbursts from you or I shall charge You
With contempt, now what is the problem?"
Then the man at the back of the court says,
"fifteen years I lived next door to that bastard
and every time I asked to borrow a hammer he said
he never had one!"
