Socialite Mrs. Silverstein goes to renown plastic surgeon Dr. Yang. Says she wants him to give her a face lift. Dr. Yang says, "Face lift is a very invasive surgical procedure we have a much more effective treatment now to maintain taut, wrinkle free skin. It also lasts longer than conventional face lift".
Mrs. Silverstein agrees to undergo the new procedure, which involves the implantation of a small knob under the back of her hairline. As the skin starts to sag all she has to do is turn the knob clockwise a bit to give her face that fresh young unwrinkled look again.
This works fine for about 3 years after which she shows up at Dr Yang's office and tells him it appears the treatment is no longer as she now has enormous bags under her eyes.
Dr. Yang looks her over with furrowed brow and finally proclaims, those aren't bags under your eyes.
It's your tits.
Mrs. Silverstein appears enlightened by the prognosis and says, well...that explains the goatee.
