"You're in remarkable shape for a man your age," said the
doctor to the ninety-year old man after the examination.
"I know it," said the old gentleman. "I've really got only
one complaint-my sex drive is too high. Got anything you can
do for that, Doc?"
The doctor's mouth dropped open. "Your what?!" he gasped.
"My sex drive," said the old man. "It's too high, and I'd like
to have you lower it if you can."
"Lower it?!" exclaimed the doctor, still unable to believe what
the ninety-year old gentleman was saying. "Just what do you
consider 'high'?"
"These days it seems like it's all in my head, Doc," said the
old man, "and I'd like to have you lower it a couple of feet
if you can."
