Three lively grandmas were sitting on a bench outside their retirement home, chatting away, when an old gentleman walked by.
“Hey there! I bet we can guess your age exactly!”
He chuckled and said,
“Oh really? I doubt that!”
The grandma winked and replied,
“Go on then, humor us — drop your pants and we’ll tell you!”
He turned red, but curiosity got the best of him. He looked around, then quickly did as she said.
The ladies made him spin in a circle and jump once or twice for good measure.
Then, in perfect unison, they shouted,
“You’re 87!”
The old man gasped,
“That’s unbelievable! How did you know?”
The grannies roared with laughter and said,
“Easy! We were at your birthday party yesterday!”
