An old couple were walking down the street. They went to cross the road and the old man got hit by a car. The old lady is screaming for help. Help help I need a doctor. Is there a doctor here in the crowd? She screamed. A man in a suit turned up and says Yes Im a doctor. Can you help him begged the old lady. The doctor looks over the old man and says yes I can help. He pulls out a gun and shoots the old man dead. What did you do that for asked the widow. What kind of doctor are you?? A Veterinarian madam!
