Twice in this chapter the narrator tells us he stands next to a "crazy cannon" while watching the football game. How might this prove to be important? What does this say about the narrator

Holden is at a Pencey football game. While the crowd is excited, Holden refuses to be part of them. He considers them phony or "crazy cannons". Holden thinks the football game is stupid. Holden's comments isolate him from the people and surroundings in this life. This is a reoccurring motif throughout the story.
