Uncle Alec was taking his evening walk when he chanced upon a lady of the night, who was leaning against a lamp post.
The lady called out to Uncle Alec, “Hey old man, why don’t you give it a try?”
Uncle Alec replied, “No, young lady, I don’t think I can.”
The woman persisted, “Oh come on, let’s give it a try!”
Uncle Alec agreed and went with her into a seedy hotel room. He surprised her with the rigour with which he performed.
The woman said, “I can’t believe you said you don’t think you can! You performed like a young boy!”
Uncle Alec replied, “Oh that!! That’s not a problem at all, what I can’t do is pay!”
