Small Organ

A fellow picked up a girl in a bar and after a few drinks they went home together.

After some more drinking and talking, they got undressed and climbed into bed.

After a few minutes, the girl started laughing.

The fellow asked her, "What's so funny?"

"Your organ," she laughed, "It's a bit on the small side!"

He shot back acidly, "Well, it's not used to playing in cathedrals."
