A woman who had been married twice and divorced twice was fed up. Her
   first husband beat her, and her second husband ran away with another
   woman. Plus, she couldn't find a new lover who could satisfy her
   sexually, so she put an ad in the classifieds:
   Wanted: A good looking, single guy who won't beat me, won't leave me,
   and is good in bed.
   About a week later, her doorbell rings. She opens the door to find a
   man with no arms and legs on her front porch.
   "I'm here about your ad," he says.
   "You must be mistaken," she says.
   "Let me explain," he says. "I can't beat you, I don't have any arms.
   And I can't run away because I don't have any legs."
   "But," she asks, "How do I know you're good in bed?"
   "I rang the doorbell, didn't I?"
