Three cheeky old grannies were sitting on a bench outside the nursing home when an old grandpa strolled by. One of the grannies, always up for a challenge, yelled out, “We bet we can guess how old you are!”
The old man smirked and said, “No way, you old fools! There’s no way you can guess it!”
One of the grannies, never one to back down, said, “Oh, we can! Just drop your pants and underwear, and we’ll tell you your exact age!”
A little embarrassed but eager to prove them wrong, the old man pulled his pants down. The grannies then asked him to turn around a few times and jump up and down a few times.
With grins widening, they all shouted in unison, “You’re 87 years old!”
The old man, standing there with his pants around his ankles, was stunned. “How did you guess?”
The grannies burst out laughing, slapping their knees, and grinning from ear to ear. “We were at your birthday party yesterday!”
