An octogenarian in a nusing home went up to a woman and said: "Bet you don't can't tell me how old I am." The woman said: "Yes I can." The man said, "Go ahead, guess." The woman replied "Only if you'll take your pants down." He said "Are you serious?" She replied, "Yes, take your pants down and I'll tell you your age." So he drops his pants, and after examining him carefully she says "Look at that. You're 84." He says, "My goodness, how did you do that?" She said, "You told me yesterday."
