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."
