Lawyers never use his heart

A man affected by acute heart attack and was brought to Emergency Unit room . Doctor said to him that his soul is helpless unless he get heart transplantation at that time also.

Another doctor entrance to the room and said, "You are lucky, there are two hearts that are available, so you just have to choose one. The one belonging to a lawyer and the other one belong to of a social worker."

The man quickly replied, "Lawyer's heart."

Doctor said, "Wait! Don't you need a little time to get to know their background before making a decision?"

The man replied, "I am already quite familiar. We all know that social workers have the heart blood thirsty while lawyers never use his heart. So I believe the lawyer's heart is still in a good condition!"
