Trevor: I asked for a fair day's pay for a fair day's work. Well, he kinda got a little angry. So, I admit, I kinda got a little angry too.
Michael: Did you kill him?
Trevor: What kinda fucking animal do you take me for? No, I didn't kill him!

Michael sighs with relief

Trevor: But I did kidnap his wife.

Dr. Isiah Friedlander: Your son, James. He's a good kid?
Michael De Santa: He's a good kid? A good kid? Why? Does he help the fucking poor? No. He sits on his ass all day, smoking dope and jerking off while he plays that fucking game. If that's our standard for goodness... then no wonder this country's screwed.

Lamar: The fucker got fucked. He fucked the fucker himself.
Trevor: Shut up.

Floyd: You gotta go, both of you. My girlfriend, she'd kill me if she knew I had guests.
Trevor: Not much of a girlfriend if she don't like your family. Now would you get me a fucking drink? I'm not gonna ask you again!

We are about to put the Darwinism back in Social Darwinism, and brother, it's gonna be fun.
