How To Guess Your Age

[kevjohn]

Three mischievous old Grandmas were sitting on a bench outside a nursing home when Grandpa Andy walked by.

One of the old Grandmas yelled out, ' Bet we can tell exactly how old you are.'

Old Andy 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 underpants and we can tell your exact age.'

Embarrassed just a little, but anxious to prove they couldn't do it, Grandpa Andy 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, Grandpa Andy 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!'
