real art

"An art dealer once went to Picasso and asked him to look over some alleged Picassos he'd been offered, and pick out the fakes. Picasso obligingly stacked the paintings into two piles, "real" and "fake." Then, as he threw one canvas into the fake pile, the art dealer cried, "But no, Pablo. That's not a fake. I was visiting here the week-end you painted it." "No matter," said Pablo with the dignity of a great magician, "I can fake a Picasso as well as any thief in Europe."
