Guess Your Age

Four old naughty grannies were sitting at a table in a retirement complex when old grandpa walked in. One old grandmother cried out to him, “We bet we can tell you exactly how old you are.”

The old man said, “You can not really guess exactly my age, you bunch of old fools.”

The old grandmother said, “We certainly can do it! Drop down your pants and underpants and we’ll tell you exactly your age.”

A bit dismayed, but determined to prove that they could not, he dropped his pants and underpants down.

The grannies told him to turn around a few times, and than made him jump up and down several times. Then they shouted in unison, “You’re 87 years old!”

With the pants around his ankles, the old man asked, “How in Hell did you guess that?”

Roaring with laughter, tears on their cheeks, the old ladies shouted in unison, “Yesterday… we were at your birthday party!”
