A middle aged lady goes to her cosmetic surgeon to see what her
options are concerning her rapidly sagging face. "We can give
you an old-fashioned face-lift", he says, "or we can use a
new high-tech procedure called 'the knob'".
"What's 'the knob'', doctor?", she asks.
He replies, "It's procedure where we install a knob under your
hair on the back of your head We then connect it to the
facial muscles which sag, and whenever you start to notice any new
wrinkles and sagging, just tighten the knob a few turns and your skin
will be nice and tight again."

"Oh, YES, doctor! That is exactly what I would like to have",
she says excitedly. The operation is a complete success and she
looks 15 years younger. As time passes, whenever she
notices any new sagging, she simply tightens the knob and VOILA! Her
face is again beautiful.

One day about 8 years later she wakes up one morning and sees two
very large bags under her eyes. Alarmed, she calls her doctor
and reports the bags. "Come down to my office right away and let
me check it out!" the doctor tells her.

After examining her, he says, "You've been tightening the knob WAY
too much!!! Those bags under your eyes are your breasts".

The lady sighs and says, "Well! I guess that explains
the goatee!"
