Holden Caulfield, the protagonist of J.D. Salinger's The Catcher in the Rye, seems to be infatuated with the phonies of the world. He calls his schoolmates, actors in New York, and girls in a bar all phonies. Curious enough, Holden proves himself to be the greatest phony of all of the characters in Salinger's novel.
Holden calls his schoolmates phonies in chapter two. During a conversation with Mr. Spenser, Holden goes on an internal rant, providing information for his audience regarding the phony nature of everyone at Elkton Hills (his school before Pencey Prep): "One of the biggest reasons I left Elkton Hills was because I was surrounded by phonies."
Later in chapter three, Holden talks about his schoolmates at Pencey Prep being phony. First he talks about Ossenburger: "I just see the big phony bastard shifting into first gear and asking Jesus to send him a few more stiffs." Later, he talks about Stradlater being a phony: "He was at least a pretty friendly guy, Stradlater. It was partly a phony kind of friendly, but at least he always said hello to Ackley and all."
At one point, Holden even nonchalantly calls himself a phony: "I stopped on the way, though, and picked up Ackley's hand, and gave him a big, phony handshake."
Overall, Holden simply thinks that the entire world is phony--himself included.
