Three elderly ladies were sitting on a bench outside their home for seniors when an older man walked by. One lady said, “We can guess how old you are.”

The man replied, “No way you can guess right, you old ladies.”

The same lady said, “Yes we can! Just take off your pants and underwear, and we’ll tell you your age.”

Feeling a bit shy but wanting to prove them wrong, he did it. The ladies told him to turn around and jump a few times.

Then they said, “You’re 87 years old!”

The man, with his pants still down, asked, “How did you know?”

Laughing and smiling, the ladies said together, “We were at your birthday party yesterday!”
