The Nursing Home

Three mischievous Grandmas were sitting on a bench outside a nursing home when an old gent walked by. And one of the Grandmas called 'We bet we can tell you exactly how old you are!'

The old man said, 'There's no way you can guess it, you old fools.'

Another of the Grandmas said, 'Sure we can. Just drop your pants and undershorts and we'll tell you 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 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?'

The three ladies happily said in unison - 'We were at your birthday party yesterday!'
