Three mischievous old grannies were enjoying a sunny day on a bench outside their nursing home. They couldn’t help but notice an old grandpa walking by. With mischievous grins, one of the grannies called out to him, “Hey there, we bet we can tell exactly how old you are!”

The old man, feeling confident, replied, “There is no way you can guess it, you old fools.”

Unfazed by his challenge, one of the grannies boldly declared, “Oh, we can! Just drop your pants and under shorts, and we’ll prove it to you.” The grandpa blushed a little, but he was curious to see if they could actually guess his age. So, he decided to play along and lowered his pants.

The grannies instructed him to turn around a couple of times and jump up and down several times. They observed him carefully, exchanging knowing looks. Then, with mischievous joy, they gleefully announced, “You’re 87 years old!”

The grandpa, standing there with his pants down by his ankles, was dumbfounded. He couldn’t believe they had guessed correctly. Curiosity got the better of him, and he asked, “How in the world did you guess?”

The three grannies burst into laughter, slapping their knees and grinning from ear to ear. Finally, one of them happily replied, “Well, dear, we were actually at your birthday party yesterday!”

Even in their golden years, these mischievous grannies know how to have some fun!
