A really bad neighbor
The judge says to a double-homicide defendant, "You're charged with beating your wife to death with a hammer."
A voice at the back of the courtroom yells out, "You killer!"
The judge says, "You're also charged with beating your mother-in-law to death with a hammer."
The voice in the back of the courtroom yells out, "You sorry no good killer!"
The judge stops and says to the guy in the back of the courtroom, "Sir, I can understand your anger and frustration at these crimes but no more outbursts from you, or I'll charge you with contempt. Is that understood?"
The guy in the back of the court stands up and says,
"I'm sorry, Your Honour, but for fifteen years I've lived next door to that guy, and every time I asked to borrow a hammer, he said he didn't have one."
