This old man marries a girl barely out of her teens. Needless to
 say she is asking for it so whenever they get into bed on the
 wedding night she asks him "So are we going to have rampant sex
 tonight?"
 
 The man responds by raising his hand and outstreching his fingers.
 
 "What? Five times?" asks the eager girl.
 
 "No", he replied. "Pick a finger".
