that night, at six-ten p.m., the borenchuck family of selby, south dakota, sat down to their evening meal. just as they started in on the soup, a rain of empty tin cans clattered down, splashed into the soup, raised a welt on the forehead of borenchuck senior, settled down to a gentle, steady klunk! klunk! klunk! and inexorably began to pile up on the dining-room floor. they seemed to materialize from a plane just below the ceiling. the police called the fire department and the fire department stared helplessly and recommended the sanitation department.
