In a casserole dish layer 1 can drained corn, then half the oysters(chopped or left whole), then half the crackers, coarsely crumbled, then dot with butter, and sprinkle on salt and pepper. Layer again. Optional sprinkle with parmesan cheese. Beat together 2 eggs and about a cup of milk (optional flavoring- add Worcestershire sauce)and pour it all over. Using a knife to put through the layers to be sure that the milk and eggs go down through the bottom layer. If needed, add more eggs and milk as the milk mixture needs to cover up to the top of the crackers. Bake at 350 for an hour. If made ahead of time and refrigerated, reheat for at least 20-25 minutes.
