Lester, an aged pensioner in the nursing home, approached Louise, another resident. He said, "See if you can guess how old I am."
Louise took one look and said, "DROP YOUR PANTS!"
Lester did so, and Louise looked him up and down for a few seconds, and said, "DROP YOUR DRAWERS!"
So Lester dropped his underwear and stood before Louise in all his glorious manhood. Louise looked at him thoughtfully a long time, and finally said, "NINETY TWO!".
"That's right!", said Lester, incredulously, "How did you know?"
"Because you told me yesterday."
