Three mischievous old Grandmas 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.



The Grandmas asked him to first turn around

a couple of times and to jump up and down

several times.



Then they all piped up and said,

"You're 87 years old!" Standing with his pants

down around his ankles, the old gent asked,

"How in the world did you guess?"



Slapping their knees and grinning from ear to ear,

the three old ladies happily yelled in unison...

"We were at your birthday party yesterday!"

lol!!!! Now that's a knee slapper!
