At the very beginning of The Catcher in the Rye, Holden Caulfield makes a statement filled with situational irony and containing an allusion to Charles Dickens. He begins his narration by saying:
If you really want to hear about it, the first thing you’ll probably want to know is where I was born, and what my lousy childhood was like, and how my parents were occupied and all before they had me, and all that David Copperfield kind of crap, but I don’t feel like going into it, if you want to know the truth.
Holden finds a lot of things ironic about his prep school, Pencey. One of the clearest instances of situational irony to be found, in his opinion, is the regular thievery among the students:
Unlock with LitCharts A+Pencey was full of crooks. Quite a few guys came from these very wealthy families, but it was full of crooks anyway. The more expensive a school is, the more crooks it has—I’m not kidding.
Throughout The Catcher in the Rye Holden reads voraciously but uses words and references incorrectly, often making them up when he can't remember the exact term he's looking for. These malapropisms are situationally ironic, since Holden often tries to present himself in a distinguished, sophisticated manner but actually ends up highlighting his own naivety and inexperience. For example, he lies to Sunny, the sex worker, about an operation on his “clavichord,” and when she asks what it is, he says:
Unlock with LitCharts A+“The clavichord?” I said. “Well, actually, it’s in the spinal canal. I mean it’s quite a ways down in the spinal canal.”
