An elderly man was having a calm walk when he happens to pass a brothel.
One of the prostitutes calls out: “Hey Grandpa! Why don’t you try?
The old man replies: “No, my child, I cannot!”
The prostitute: “Cheer up !!! Let us try!!!”
The elderly man enters and performs like a 25 year old.
The prostitute says:”Oh Gosh! And you still say you cannot!”
The old man replies: – “Aaah, sex I can, what I cannot is pay!”
