"Sister Mary Katherine." exclaimed Jack, "I could never do that! I've never sold alcohol to a nun in my life!""
"Oh Jack," she responded. "its only for Mother Superior." Her voice dropped. "It helps her constipation, you know.
So Jack sold her the brandy. Later that night Jack closed the store and walked home. As he passed the nunnery, who should he see but Sister Mary Katherine. And she was snookered. She was singing and dancing, whirling around and flapping her arms like a bird in flight, right there on the sidewalk.

Sister Mary Katherine didn't miss a beat as she replied: "And so it is, me lad. When she see's me, she's going to shit!"
