Three mischievous old Grannies were sitting on a bench outside a nursing home. When an old Grandpa walked by. And one of the old Grandmas yelled out saying, βWe bet we can tell exactly how old you are. βThe old man said, βThere is no way you can guess it, you old fools.β
One of the old Grandmas said, βSure we can! Just drop your pants and under shorts and we can tell your exact ageβ¦β Embarrassed just a little, but anxious to prove they couldnβt 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, βYouβre 87 years old!β Standing with his pants down around his ankles, the old gent asked, βHow in the world did you guess?β Slapping their knees and grinning from ear to ear, the three old ladies happily yelled in unisonβ¦βWe were at your birthday party yesterday!β
