One day this lady goes into a plastic surgeon's office. She wanted something 
that would take away the wrinkles in her face. The doctor suggested that they 
put a screw in her head and every time she wanted the wrinkles out of her face 
she would tighten the screw. The lady agreed to this idea and went home with a 
screw in her head.
About a month later the lady came in complaining that the screw wasn't 
working. 
"look at these bags under my eyes, they're hideous! I want my money back!" 
"Listen lady," said the doc, "those bags are your breasts and if you keep 
tightening that screw all the time you're soon gonna have a beard!"
