A woman went to a plastic surgeon for a facelift. The surgeon told her about a new procedure called "The Knob", where a small knob is placed on the back of a woman's head that she could turn to tighten up her skin to produce the effect of a brand new facelift. Of course, the woman wanted "The Knob." Over the course of the years, she turned the knob many times and the effects were wonderful - she remained young looking and vibrant. After 15 years, she returned to the surgeon. "All these years, everything has been working just fine. I've turned the knob many times and I've always loved the results. But now I've developed two annoying problems: First, I have these big bags under my eyes and the knob just won't get rid of them." The doctor looked at her closely and said, "Those aren't bags, those are your breasts." The woman said, "I guess that explains the goatee."
