One for the "old ladies"

[dubl_t]

3 Grandmas were sitting on a park bench, when an old Grandpa walked by.

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!'
