There was a man and a woman in an old folks home. The man says to the woman, i bet you cant guess what age i am. The woman says, i'll give it a go, but first pull down your pants. The man pulls down his pants, the woman instructs him to pull down his underpants too, so he does. She taps around down there for a couple minutes then looks at him and says, Youre 97. The man asks her, how do you know that? The woman answers, because you told me yesterday.
