Paul Newman on sunglasses:

‘I owe fans the best performance I can give; I owe them an appearance on my set exactly on time; I owe them trying to work for the best I can, not just for money. But if somebody says that what I owe him is to stand up against a wall and take off my dark glasses so he can take a picture of my eyes, then I say, ‘No, I don’t owe you that.’ I try not to be hurtful. I say something like, ‘If I take off my glasses, my pants will fall down.’ ‘
