Marvin was enjoying a beer in the outdoor seating area at his local tavern when a Nun suddenly appeared at his table and started decrying the evils of drink.
“You should be ashamed of yourself!” she chastised. “Drinking is a Sin! Alcohol is the devil’s drink!”
“How would you know, Sister?” asked Marvin sceptically.
“Mother Superior told me so,” came the nun’s resolute reply.
“But have you ever had a drink yourself?” pressed Marvin. “How can you be sure that what you are saying is right?”
“Don’t be ridiculous,” scoffed the nun. “Of course I have never taken alcohol myself.”
“Then let me buy you a drink,” offered Marvin. “If you still believe afterwards that it is evil, I will give up drink for life.”
“How could I, a Nun, sit outside this public house drinking?!”
“I’ll get the barman to put it in a teacup for you, then no one will know.”
The Nun reluctantly agreed, so Marvin went inside to the bar and ordered, “Another beer for me, and a triple vodka on the rocks,” then he lowered his voice and said to the barman, “and could you put the vodka in a teacup?”
“Oh no!” howled the barman. “Is that blasted nun back again?”
