"There's a drawing by Rembrandt, I think it's the greatest drawing ever done. It's in the British Museum and it's of a family teaching a child to walk, so it's a universal thing, everybody has experienced this or seen it happen. Everybody. I used to print out Rembrandt drawings big and give them to people and say: 'If you find a better drawing send it to me. But if you find a better one it will be by Goya or Michelangelo perhaps.' But I don't think there is one actually. It's a magnificent drawing, magnificent."
