All of them crustacians reminds me of when I was young and in an expensive restaurant in Tangiers. They had shrimp on the menu. I ordered them. The waiter set a gigantic platter of LIVE huge shrimp on the table. Trying to look sophisticated and cosmopolitan I took it all in stride and tried tried to maintain an air of dignity as I chased a shrimp across the table top, with a fork. The restaurant was in hysterics and I was trying to keep from looking like a fool. finally the waiter whispered to me. "You are supposed to point to the shrimp you want the chef to cook for you"
