A man murders a wino on Skid Row and then cuts off the wino’s arms. The man mails each arm to a different address. The man then goes the train station. Another man sees him, becomes enraged, and kills the first man. Why did the last man become enraged and kill the first man?

Are you going to submit that to the lateral puzzles thread?
