A rich woman wants to commission a well-renowned artist to paint a portrait of her. She arranges to meet with him to discuss terms.

She tells him, "Price is no object, but I have only one condition. I want you to paint me in the nude."

This takes him a bit by surprise, as he is a married man, "Uh, I apologize ma'am, but I don't think I can agree to that-"

"I'll pay you ten thousand dollars," she interrupts him.

Again he is taken aback and considers, "Well... Let me ask my wife first, and if she consents then we have a deal."

They agree and he goes home. The next day, the artist returns. He gives the lady the verdict, "All right, my wife says it is fine, but you'll have to let me keep my socks on so I have somewhere to wipe my brushes."
