An artist asked the gallery owner if there had been any interest in his paintings currently on display.
"I've got good news and bad news," the owner replied.
"Give me the good news first," the artist demanded.
"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 could possibly be the bad news?"
With concern, the gallery owner replied, "The guy was your doctor."
