A traveler, lost on a rainy night, stumbles across a monastery and takes shelter there.
Fortunately, she's just in time for dinner, which turns out to be the best fish and chips she's ever had. After dinner, she goes into the kitchen and asks "Excuse me, but who cooked that meal?"
Two of the brothers step forward in response. "Hello, I'm Brother Michael, and this is Brother Charles."
"Pleased to meet you both. I just wanted to thank you for a wonderful dinner." Both brothers smile and murmur "Thank you, our pleasure."
"Out of curiosity, who cooked what?"
Brother Charles said, "Well, I'm the fish friar."
She winces, turns pale, and says to the other brother, "Oh, no. Then you must be..."
"Yes, I'm the chip monk."
