Three mischievous old Grannies were sitting on a bench outside a nursing home. When an old Grandpa walked by. And one of the old Grandmas yelled out saying, “We bet we can tell exactly how old you are.

”The old man said, “There is no way you can guess it, you old fools.” One of the old Grandmas said, “Sure we can! Just drop your pants and under shorts and we can tell your exact age…” Embarrassed just a little, but anxious to prove they couldn’t do it, he dropped his drawers then,

The three mischievous grannies looked him over carefully, inspecting from every angle. They prodded here, poked there, and even gave a few things a little tug. After a few moments of examination, they huddled together, whispering and giggling.

Finally, one of the grannies turned to the old man and confidently declared, “You’re 87 years old!”
The old man was astonished. “How on earth did you figure that out?” he asked, completely bewildered.

The grannies burst into laughter, and one of them replied, “We were at your birthday party yesterday!”
