Arty Fact

Picasso was fond of drawing on napkins at some of the restaurants he visited.  One day he was sitting at a table in a small Parisian cafe.  A well-dressed woman approched and asked if he could draw a sketch of her on a napkin. 'You can charge whatever you want,' she said.

Picasso asked a waiter for two napkins.  He pulled out his pen and drew a picture on the first napkin.  On the second he wrote the astronomical price for the drawing.  The woman gasped. 'Why is it so expensive? It only took you a few minutes to draw the sketch.'

Picasso thought for a moment, and replied, 'It took me a lifetime to learn how to draw that sketch.'
