Malcolm: There you are. You took off so fast from school, we didn't get a chance to talk about what happened to Diane.
Lois: I'm a very busy woman, Malcolm. It isn't easy running this household.
Malcolm: I can imagine cooking, shopping... cutting the heads off of dolls.
Lois: I have no idea what you're talking about.
Malcolm: Come on, Mom, it's pretty obvious what's going on here, and I think it's sick! Did you see Diane's reaction?
Lois: No, I didn't... Was she crying?
Malcolm: She had to be wrapped in a blanket and carried to the school nurse's office.
Lois: Terrible, just terrible. There's a salad in the fridge and you boys can make yourselves sloppy Joe's whenever you're hungry. I've got some errands to run.
Malcolm: Oh, "errands," right? I know what you're up to, Mom.
Lois: Oh, yes, Malcolm, you've caught me. I've got to return an overdue video, go to the cleaners, and pick up milk and cereal for the morning. Guilty as charged.
Malcolm: Oh, nice try. Now, I want you to look me in the eye and- [Lois closes the bathroom door] Mom, I know you're behind all this, and sooner or later you're going to have to talk to me.
Lois: [o.s.] For God's sake, Malcolm, can't I have a moment's rest?
Malcolm: No, you can't! Tell me, did it feel good to cut through Elmo's neck? Did it?! Mom? Mom? [opens door to find Lois gone and the window open]
