Iris: I don't like what I'm doing, Sport.
Sport: Ah, baby, I don't want you to like what you're doing. If you like what you're doing, then you won't be my woman.
Iris: God, you're square.
Travis Bickle: Hey, I'm not square, you're the one that's square. You're full of shit, man. What are you talking about? You walk out with those fuckin' creeps and low-lifes and degenerates out on the streets and you sell your little pussy for peanuts? For some low-life pimp who stands in the hall? And I'm square? You're the one that's square, man. I don't go screwing fuck with a bunch of killers and junkies like you do. You call that bein' hip? What world are you from?
