There's a famous story about Picasso. People would often approach him asking him to authenticate their artworks. One day this happened while an art dealer friend was present. "Fake!", says Picasso. The art dealer was skeptical, so he gave one of his own Picassos to a third party and asked him to check. "Fake!", says Picasso. "But Pablo, I saw you draw that. You gave it to me with your own hands!" "Bah. Anyone can do a fake Picasso. I often do them myself."
