An old man is walking in Perth and passes a hooker standing at her door.

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

                                                He replies: "No girl, that's no longer possible for me."

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

                                             So he made up his mind and they both go inside.
                                           
                                            They undress and he performs like a young buck, 5 times in a row.

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

                                            Says the old guy: "Oh, the sex part is still going well,

                                            it's the PAYMENT that is no longer possible!

                                           Old age and experience always out does youthful exuberance
