Drunk Nun Joke

A nun walks into a corner shop and asks the man behind the counter for a bottle of whiskey.

"But you're a nun," the shopkeeper says confusedly. "You're not supposed to drink alcohol - if I sell this to you, it'll be against your - and my - religious beliefs."

"Oh no," the nun says sweetly. "You don't understand. It's for the Mother Superior's constipation."

"Oooh," he nods. "Right. Well, seeing as it's for health reasons...I'll sell it to you."

So he sells her the bottle of whiskey and off she goes.

Two hours later, the man shuts up the shop, and begins to walk down the street when he notices the nun - she is extremely drunk, swinging from the lampposts and singing merrily.

"Excuse me!" the shopkeeper yells, as he approaches the nun. "I thought you said that bottle of whiskey was for the Mother Superior's constipation!"

The nun stops swinging from the lamppost and looks at him through hazy eyes. "Aye!" she says. "It was! And when she sees me, she'll shite herself!"
