The Hooker

An old man is walking around Kings Cross and passes a hooker standing on a corner of a brothel.

She asks him: "Granddad, why don't we give it a try?”

"No girl, that is no longer possible for me” he replies.

Says the hooker: "Come on, what have we got to lose, we can give it a try!?”

They both go inside and go to one of the rooms.

They undress and then he acts like a young man and performs 5 times in a row for over a hour.

"Oh my goodness", says the hooker, breathless "and you said that it was no longer possible for you?!”

Says the old man: “Oh, my screwing is still going well, it's the paying for it that is no longer possible..”
