Three old ladies were sitting on a bench in the grounds of the old peoples' home when one of them said, "Let's play a game with old Tom". So as Tom walked past one said, "I bet I can guess your age."
Tom replied, "Go on then".
She told Tom to drop his trousers and pants and then she cupped his balls in her hands and squeezed them gently.
She said, "You are 83."
Tom replied, "Bloody hell, how do you know that?"
She answered, "I was at your birthday party last week."
