A sheep or a good man?

Yesterday I was sitting in a restaurant, waiting for my brother, when I saw a man come in and make his way toward the cashier. When he was a few feet away one of the employees said, “Excuse me, sir, do you have a mask?” The man sighed and nodded as he reached into his pocket. After he had the mask on the man said, “I’ll be a sheep.” Then, he kind of turned to look around and I caught his eye and said to him, “It’s funny, but you don’t look like a sheep. You look like a good man.”
