A fellow picked up a girl in a bar and took her home with him.  After some
preliminary drinks and talk, they got undressed, climbed into bed and
generally got organized for a leg over.  After a few minutes, the girl
started laughing. The fellow asked her what she found so amusing.  "Your
organ," she replied. "It's a bit on the small side."
    Hurt, he replied: "It's not used to playing in cathedrals."
