The Pope replied, "First the girl must be blind, so that she cannot see with whom she is having sex. Second, she must be deaf, so that she cannot hear with whom she is having sex. And third, she must be mute so that if she somehow figures it all out, she can tell no one." After another long pause, a voice finally asked, "And the fourth condition?"
