An artist had been working on a nude portrait for a long time. Every day, he was up early and worked late - bringing perfection with every stroke of his paint brush. As each day passed, he gained a better understanding of the female body and was able to really make his paintings shine.

After a month, the artist had become very weary from this non-stop effort and decided to take it easy for the day. Since his model had already shown up, he suggested they merely have a glass of wine and talk - since normally he preferred to do his painting in silence.

They talked for a few hours, getting to know each other better. Then as they were sipping their claret, the artist heard a car arriving outside. He jumped up and said, "Oh no! It's my wife! Quick, take off your clothes!"
