A woman places an ad in the local newspaper. “Looking for a man with three qualifications: won’t beat me up, won’t run away from me, and would be IMMENSELY good in bed”.
Two days later her doorbell rings. “Hi, I’m Sam. I have no arms so I won’t beat you, and no legs so I won’t run away”.
“What makes you think you are great in bed?” the woman retorts.
Sam replies, “I rang the doorbell, didn’t I?”
