An artist asked the gallery owner if there had been any interest in her paintings that were on display.

“Well, I have good news and bad news,” the owner responded. “The good news is that a gentleman noticed your work and wondered if it would appreciate in value after your death. I told him it would and he bought all 10 of your paintings.”

“That’s wonderful,” the artist exclaimed. “What’s the bad news?”

“The gentleman was your doctor.”
