Niles: Give me the brick, Frasier.
Frasier: And let him get away with this?
Niles: I know. I know. What the gallery owner did was wrong. It was humiliating. But if you throw that brick through that window, you will have lost something more valuable than your money. You will have lost ... your mind. Frasier, you can't do this!
Frasier: Well, Niles, if you were strong enough to show restraint after so much humiliation, not to mention the nicknames-
Niles: Nicknames? There were nicknames?
Frasier: You didn't know that? Oh, dear God, yes. Peachfuzz, Jingle Bells- I can't remember the rest.
Niles: "Peachfuzz"?
Frasier: Yes, I believe Coach Medwick made that one up himself. Well, anyway, here you are. I won't be needing this any more.
Niles: I'm proud of you. [Niles throws the brick through the gallery window]
Frasier: My God, Niles. What are- What have you done?
Niles: I struck a blow for justice. Nobody calls me Peachfuzz! Now let's get the hell out of here!
Frasier: Niles, what are you doing now?
Niles: We may be barbarians, but we pay for our pillaging.
Frasier: Come on. Go! Go! Go! Go!
