Parmigiano-Reggiano

“A man who has been three years biting his nails on a desert island, Jim, can’t expect to appear as sane as you or me. It doesn’t lie in human nature. Was it cheese you said he had a fancy for?”

“Well, Jim,” says he, “just see the good that comes of being dainty in your food. You’ve seen my snuffbox, haven’t you? But you never saw me take snuff, did you? The reason being that in my snuffbox I carry a piece of Parmesan cheese—a cheese which is made in Italy, very nutritious.”
