An artist asked the gallery owner if there had been any interest in his paintings on display at that time. "I have good news and bad news, " the owner replied.

"The good news is that a gentleman enquired about your work and wondered if it would appreciate in value after your death. When I told him it would, he bought all 15 of your paintings." "That's wonderful!" the artist exclaimed.

"What's the bad news?" "The guy was your doctor."
