After three days of steadily increasing discomfort, local resident James Furness, 46, was finally in enough pain Monday to have his sprained right ankle examined by a doctor. 'Fuck it, I give,' said Furness, who twisted the ankle while mowing his lawn Friday. 'I thought it might go away by itself, or just with a little ice, but the bastard's all swollen up like a cow's.' After driving 12 miles to his doctor's office using only his left foot, Furness was subjected to a 20-minute lecture from his physician on the importance of prompt medical attention.
