Sam: You set me up! You tricked me! I hope you enjoyed your prank.
Butch: You know, you've got it so easy. You've got your Peter Pan parents and your perfect grades and your cheerleader friends. Well, some of us don't have it that great, all right?
Sam: Yeah, I know. But why do you have to make things worse? Being in the Bones of Wrath doesn't solve anything!
Butch: You don't understand. Those guys are my friends, and I don't have many of those.
Sam: Well, how about me? I wanted to be your friend!
Butch: Yeah, but not anymore.
Sam: All I know is I'd still be your friend if you'd quit being Butch and start being Brian again.
Butch: Brian's gone.
Sam: Well, that's too bad. Let me know if he comes back; I miss him. (beat) Goodbye . . . Butch.
