A doctor and a lawyer were attending a cocktail party when the doctor was approached by a man who asked advice on how to handle his ulcer. The doctor mumbled some medical advice, then turned to the lawyer and asked, "How do you handle the situation when you are asked for advice during a social function?"

"Just send an account for such advice," replied the lawyer.

On the next morning the doctor arrived at his surgery and issued the ulcer-stricken man a $50 account. That afternoon he received a $100 account from the lawyer.

"I'm beginning to think that my lawyer is too interested in making money."

"Why do you say that?"

"Listen to this from his bill: 'For waking up at night and thinking about your case: $25'."
