Three elderly women are sitting on a bench outside a nursing home.

About then, old man Cohen shuffles by, and one of the old women calls out, “We bet we can tell exactly how old you are.”

Old man Cohen stops. ‘Well, so how can you do that?” he asks.

“All you have to do is drop your pants and your undershorts and we can tell your exact age.”

Old man Cohen is a little embarrassed, but he wants to prove these ladies are wrong. He decides to play their game, and he pulls down his pants and boxers.

“Turn around, turn around,” one of the old ladies exclaims. Old man Cohen obliges them by turning around a couple of times.

“Maybe you can jump up and down a bit?” the second woman asks.

With a bit of effort, Cohen goes up and down on his toes a few times. “So it’s not so easy to guess my age?” he asks.

All of a sudden, the third elderly woman calls out, “You're 94 years old!”

Standing with his pants and boxers down around his ankles, old man Cohen is amazed. “You’re right,” he says, “but how in the world did you figure it out?”

“It was easy,” one of the women answers. “We were at your birthday party yesterday.”
