I was walking in the park the other day and saw these three mischievous old Grandmas sitting on a bench. As I walked by one of the old gals yelled out saying, 'John, we bet we can tell exactly how old you are.'
I snorted and said, 'There is no way you can guess it, you old fools.'
One of the old ladies 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, I dropped my pants and drawers (extremely glad I had no ‘hash marks’ to exhibit.)
The old hags asked me 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 65 years old!'
Standing there with my pants down around my ankles (enjoying the breeze), I was dumbfound and asked, 'How in the world did you ever guess?'
Slapping their knees and grinning from ear to ear, the three old ladies yelled in unison, 'We were at your birthday party yesterday!'
I had the last laugh, though. My birthday party was last week.
