Capt. Ramey: Who's your lawyer?
Kelly Shepard: We don't have a lawyer.
Capt. Ramey: He specifically asked that his attorney be brought down here to negotiate his surrender.
Kelly Shepard: Well, we never needed one.
Capt. Ramey: Well, you need a good one now.
The Caller: Come on, Stu! Don't you get the game yet?
The Caller: Stand up and be a man.
The Caller: The odds are even now, Stu. Isn't that what you wanted? You know where I am and you have a gun. If you have it in you, you can take me down.
Stu: Fuck! They'll kill me before I can get a shot at you.
The Caller: Ah, you're probably right. I wasn't really there anyway. You would've just spoiled some nice lady's curtains.
Stu: I'm on my knees beggin' you not to kill me.
The Caller: You can't understand the pain of betrayal until you've been betrayed.
The Caller: You'd shoot me if you had the chance, wouldn't you?
Stu: With a big fucking smile on my face.
The Caller: There's the spirit.
The Caller: I have no use for you, Stu.
The Caller: This is exciting. You get to choose between them. Kelly. Pam. BAM BAM.
The Caller: It's not in your best interest to disconnect me.
Capt. Ramey: And Jonah, don't look up.
Stu: Where? Where are you?
The Caller: There are hundred of windows out there. Why don't you check them out?
Stu: Don't you dare fucking hurt her.
The Caller: Don't I dare?
Sergeant Cole: Captain, what the fuck is up with the phone calls, man?
The Caller: What they don't know, we do to them in our minds, isn't that right?
Stu: You sick fuck.
The Caller: Perfect violation.





Answer: The pizza man is intended by the Caller to be a decoy so he can get away. The Caller sends the pizza man to the phone booth so that Stu will identify him later in the apartment, giving the police a convenient answer to the mystery while the real Caller escapes. In fact, at the end of the movie, the Caller comes to visit Stu - obviously he's not the dead pizza delivery man.
