The scene, both in the movie and the book, where Louis and his father-in-law start to fight at Gage's funeral, and knock over his coffin.
The coffin did not actually open and spill Gage's sad, hurt remains out onto the floor for all of them to gawp at, but Louis was sickly aware that they had only been spared that by the way the coffin had fallen—on its bottom instead of its side. ... Nonetheless in that split instant before the lid slammed shut on its broken latch again, he saw a flash of gray—the suit they had bought to put in the ground around Gage's body. And a bit of pink. Gage's hand, maybe. Sitting there on the floor, Louis put his face in his hands and began to weep.
