Hal: I have Kobe beef.
Reese: No way.
Hal: Yes!
Reese: That's like $60 an ounce.
Hal: I know. I won it in a Minesweeper tournament at work. Years of practicing eight hours a day has finally paid off.

Dewey: Mom, I have a proposal for you. Now, before you start poking holes in it, I'd like you to hear me out. All I want is no more school and no more big boy clothes. I'd liked to be bathed and rocked before I go to sleep and have all my food mashed up. In return, I'll be adorable and...
Lois: Are you wearing a diaper?
Dewey: I want you to know my level of commitment. [clenches face]
Lois: [o.s.] Oh, my God!

Fran: When your milk duct is blocked, it's called mastitis. It's important that you let your baby suck the obstruction out of the breast, and don't be alarmed if the baby then vomits up a cottage cheese-type substance. Now, join me over here...
Dewey: Like I needed another reason to hate cottage cheese.
Reese: I've been kind of zoning in and out here, but did she just say milk comes out of those things?
Malcolm: Reese, that's what they're for.
Reese: My God! Women are the cows of people!

Malcolm: Hey, what's all the noise? You know the rule. The only sound allowed in this room is snoring.
Dewey: I've been waiting ten years to see Conrad Horner perform, and I overslept and completely missed it.
Malcolm: So? He'll come back in a few years.
Dewey: He's 98. I got there in time to get a program off the floor and see his ambulance drive away.

Hal: Shouldn't you be in bed?
Malcolm: I got sick of lying there, so I thought I'd look on the Internet for stuff about the murders. I got police reports, crime photos, newspaper articles... There's a ton of stuff.
Hal: Really?
Malcolm: The guy's name was Gareth Stringer. Normal guy, Scout master, everybody loved him. So, one day, out of nowhere, he comes home from work and murders his entire family. They say he lived here with five headless bodies for a week before he finally killed himself.
Hal: For a whole week, huh?
Malcolm: That's where the wife's body was found. [Hal whimpers and moves] He put all the tongues in a pile right there. [Hal moves every time Malcolm points to another location] So I guess that must have been skin wall. And that was hair corner. Over there were... finger puppets?! Oh, finger puppets. Wow, the really freaky stuff happened in the kitchen. Oh, and in the bathroom and the bedrooms, too.
Hal: Malcolm, is there any place in this house where bloody pieces of dismembered bodies weren't found?
Malcolm: Well... Yes. Right there.
Hal: Right here?
Malcolm: That's where they all begged for mercy. [Hal whimpers]

Hal: Malcolm, where have you been? You got to get in on this.
Malcolm: Dad... I want skating lessons.
Hal: Son, do you know, once you start there's no going back?
Malcolm: I know.
Hal: This means total commitment. Once you begin the path, there is no leaving the path. Are you sure you're ready for that? I mean really ready?
Malcolm: I-I guess so.
Hal: Neat. We'll start tomorrow. Come on, dig in before they harden.
