Yesterday I was in the doctor's waiting room and I heard a ninety-six-year-old man pleading with the doctor for a lower sex drive.
'Surely you're imagining things,' said the doctor. 'You're ninety-six years old. Isn't all the feeling for sex just in your head?'
'Yes,' replied the elderly man, 'that's why I want you to lower my sex drive to the place where it might do more good.'
