Cass: You were gonna ask me for money? Who the hell do you think you're dealing with, some old slut on 42nd Street? In case you didn't happen to notice it, ya big Texas longhorn bull, I'm one helluva gorgeous chick.
Ratso Rizzo: You know, in my own place, my name ain't Ratso. I mean, it just so happens that in my own place my name is Enrico Salvatore Rizzo.
Joe Buck: Well, I can't say all that.
Ratso Rizzo: Rico, then.
Gretel McAlbertson: Why are you stealing food?
Ratso Rizzo: I was just, uh, noticing that you're out of salami. I think you oughtta have somebody go over to the delicatessen, you know, bring some more back.
Gretel McAlbertson: Gee, well, you know, it's free. You don't have to steal it.
Ratso Rizzo: Well, if it's free, then I ain't stealin'.
Trivia: The most famous line in this film is purely ad-libbed. Apparently a tough New York cabbie broke through and drove across one shoot, nearly running down Jon Voight (Joe Buck) and Dustin Hoffman (Enrico Salvatore "Ratso" Rizzo). Notice Voight's startled expression. Hoffman, still in character, slams on the hood and shouts at the cabbie, "Hey, I'm walkin' here. I'm walkin' here."
