Two grannies were sitting on a bench

Two grannies were sitting on a bench outside a nursing home when an old man walked by.

One of the grandmas yelled out: “We bet we can tell exactly how old you are.”

“There is no way you could guess that, you old biddies,” the man replied.

The other grandma said: “Sure we can! Just drop your pants and undershorts and we

can tell your exact age.” Embarrassed just a little, but anxious to prove they couldn’t do it, he dropped his drawers.

The grandmas asked him to first turn around a couple of times and to jump up and down several times. Then they both yelled: “You’re 87 years old!!!”

Standing with his pants down around his ankles, the old gentleman asked: “How in the world did you guess?”

Slapping their knees and grinning from ear to ear, the two old ladies giddily yelled in unison: “We were at your birthday party yesterday!”
