Peter's wife bought a new line of expensive cosmetics when she heard that they would make her look years younger. After applying the products, she asked her husband: "Darling, tell me honestly. What age would you say I am?" Looking her over carefully, Peter replied: "Let me see. Judging by your skin, 20; your hair 18; and your figure, 25." "Oh you flatterer, she gushed in delight." "No wait, Peter replied. I have not added them up yet!" (Source: Reader's Digest, Vol.81.No.482, May 2003 edition)
