There was once a lady who was tired of living alone.

 So she put an ad in the paper
which outlined her requirements. She
wanted a man who
1) would treat her
nicely,
2) wouldn't run away from her, and
3) would be good in bed. Then, one day, she heard the doorbell
ring.
She answered it, and there on the front
porch was a man in a wheel chair who
didn't have any arms or legs.
"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."
"Yes, but are you good in bed?"
"How do you think I rang the doorbell?"

Is he qualified?
