Malcolm: Dad, you've got to do something. Mom has been stalking those girls who humiliated Reese like some kind of vigilante.
Hal: What? Are you sure about this?
Malcolm: Yes. She's nailed two of them so far, and she just climbed out of the bathroom window to go get the third.
Hal: This sounds like a lot of supposition, Malcolm. I mean, it would be a different story if you had hard evidence or an eyewitness.
Malcolm: I saw her at school today. She was there when these butchered dolls' heads rolled out of one of the girls' lockers.
Hal: And what exactly do you mean when you say you were "there"?
Malcolm: Dad, stop it. Don't you care?
Hal: Of course, I care, but I think what we need right now is caution and prudence. A proactive wait-and-see... if you will.
Malcolm: So you're not going to do anything?
Hal: Listen, when your mother gets like this, we need to vigilantly keep abreast of all the developments in a fully-engaged yet cautiously-detached...
Malcolm: Oh, forget it if you're not going to help me, then I'll just stop her myself, and you can stay here and play your ridiculous little game.
Hal: Good.
