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 organised 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."
