There once was a lady who was tired of living with men who were either 
  physically abusive, who ran away from her, or who were horrible in bed. 
  
  So she put an Ad in the internet, that was asking for a man who: 
  
  1)would treat her nicely 
  2)wouldn't run away from her, 
  3)would be good in bed. 
  
  Three weeks passed, and there was no reply from any man. So she just 
  figured that there wasn't a man alive who could live up to these 
  expectations, so she just gave up. 
  
  But then, one day she heard the doorbell rang. She answered it, and 
there on the front porch was a man in a wheel chair who didn't have any arms 
or legs. 
  
  The man said 'I'm here about the ad you put in the paper. As you can 
see,   I have no arms so I can't beat you, and I have no legs so I can't run 
away from you. 
  
  The woman replied, 'Yes, but are you good in bed?' And the man said with 
a  smirk on his face, 'How do you think I rang the doorbell?'
