An artist asked the gallery owner if there had been any interest in his paintings that were currently on display.
“I’ve got good news and bad news,” replied the gallery owner.
“The good news is that a gentleman inquired about your work and wondered whether it would appreciate in value after your death.
When I told him it would, he bought all fifteen of your paintings.”
“That’s great!” exclaimed the artist.
“So what’s the bad news?”
“The man was your doctor.”
