The Artist

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 inquired 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."
