Grandma Joke :)

Three old mischievous Grandmas
were sitting on a bench outside a Nursing home.

About then an old Grandpa walked

by, and one of the old Grandma's yelled out saying, 'We bet we can tell
exactly how old you are.'

The old man said, 'There's 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 grinningfrom ear to ear, all three old Ladies happily yelled in unison--

'We were at your birthday party yesterday!'
