Remove corn from cobs by using a corn grater or knife, and mash the whole kernels a little. Slice bacon into 1-inch pieces. Cook bacon until brown in a large skillet. Remove bacon from skillet and add 1/2 stick butter to bacon grease. Over medium-high heat, pour in the corn. Fry in the grease and butter mixture. Lower the temperature and cook for 5 minutes, then put on simmer until corn is done, 10 to 15 minutes. Add black pepper, to taste. If corn seems too dry, add a little milk or water.
