Once this woman placed an ad in the local newspaper looking for a suitable
 man.  Then one day her door bell rang.  She answered it and to her dismay a
 man in a wheel chair with no arms and no legs was sitting there. 
 She says, "Can I help you?"  
 He says, "I'm here to answer your ad."  
 She says, "There must be a mistake."  
 He says, "No.  Correct me If I'm wrong, but this ad says you're looking for 
 someone who won't beat you and as you see I have no arms, right?"  
 She says, "Yeah, but..."
 He says, "You also said you want someone who won't run around on you and as 
 you can see I don't have any legs, right?"  
 She says, "Yeah, but I also said I want someone who's great in bed..."  
 He says, "Lady, how do you think I rang your door bell?"
