Lost on a rainy night, a nun stumbles across a monastery and requests shelter there. Fortunately, she's just in time for dinner and was treated to the best fish and chips she's ever had.
After dinner, she goes into the kitchen to thank the chefs.
She is met by two brothers, "Hello, I'm Brother Michael and this is Brother Charles."
"I'm very pleased to meet you. I just wanted to thank you for a wonderful dinner. The fish and chips were the best I've ever tasted. Out of curiosity, who cooked what"?
Brother Charles replied, "Well, I'm the fish friar."
She turns to the other brother and says, "Then you must be"?
"Yes, I'm the chip monk."
