An elderly patient needed a heart transplant...
An elderly patient needed a heart transplant and discussed his options with his doctor. The doctor said, "We have 3 possible donors; the 1st is a young, healthy athlete who died in an automobile accident, the 2nd is a middle-aged businessman who never drank or smoked and who died flying his private jet. The 3rd is an attorney who died after practicing law for 30 years. Which do you want?""I'll take the lawyer's heart", said the patient. After a successful transplant, the doctor asked the patient why he had chosen the donor he did. "It was easy", said the patient, "I wanted a heart that hadn't been used."

A little change
The patient shook his doctor's hand in gratitude and said:"Since we are the best of friends, I would not want to insult you by offering payment. But I would like for you to know that I had mentioned you in my will.""That is very kind of you," said the doctor emotionally, and then added, "Can I see that prescription I just gave you? I'd like to make a little change..."
