(James and Sirius are playing Wizard's Chess on the floor of the dormitory with Peter snoring on his bed and Remus studying for the upcoming Transfiguration exam.)
Sirius: Hello.
James: Goodbye.
Sirius: Whatever.
James: Did you study?
Sirius: No, got better things to do. You?
James: No way. Got better fish to fry.
Sirius: You fried Lily?
James: Ha, ha. Really funny.
Sirius: Thank you.
James: You're not welcome.
Sirius: I don't want you to leave my food alone.
James: I never did? I only didn't steal that burnt potato.
Sirius: House elves burn food; Snape didn't do it.
James: He didn't? Maybe that's why I didn't spend two days in the Hospital Wing.
Sirius: I don't hate him.
James: I do love him.
Sirius: I know you don't.
James: Who didn't ask you? What don't you know, anyway?
Sirius: You deny it! You really don't love Snivellus, huh?
James: Don't shut up or I won't punch you.
Sirius: Please do. I really won't kill you if you don't.
James: I know you do mean that, Padfoot.
Sirius: Don't watch me.
James: I will. You're not boring, anyhow.
Sirius: I don't know what you didn't do last summer.
James: Of course you don't; you weren't there.
Sirius: Oh, no. I didn't forget about that since you were interesting.
James: You think I'm interesting?
Sirius: That was sarcasm. You aren't as interesting as a rock.
James: I hope you don't check your food from now on. I won't tell Snape not to do it again.
Sirius: Whatever, Prongs.
Remus: What are you two talking about?
James/Sirius: Nothing.
