Lois: Malcolm, no. If you want this thing so badly pay for it with your own money. You're going to start to baby-sit next week. Just save up.
Malcolm: I don't even know what they're going to pay me.
Lois: I'll tell you what they're going to pay you. They're going to pay you what all jobs pay - less than you're worth and just enough to keep you crawling back for more. Now go on, it's bedtime.

Lois: $90 for a toy?
Malcolm: It's not a toy. It's a robotics kit. You build a little mechanical rover. It teaches you about electronics and engineering.
Lois: Does it teach you to pick up your socks? That I'd be interested in.
Hal: Besides, son robots are evil.
Malcolm: What?!
Hal: Westworld, Terminator, the creepy maid from The Jetsons. How much scientific proof do you need?

[Malcolm and Reese are playing a video game, featuring screaming and shouting, as Dewey sits on the couch behind them]
Dewey: Pass the chips, please.
Reese: Here you go.
Dewey: Thank you.
Reese: You're welcome.
Malcolm: Wow, that was a really great move. My head just went flying.
Reese: Thank you.
Malcolm: You're welcome.
Lois: I told you boys these games are too violent. Here, watch something wholesome.
Man: [sings on TV] The sun is a mass of incandescent gas A gigantic nuclear furnace Where hydrogen is built
Dewey: Give me more chips!
Reese: Get your own, doofus!
Malcolm: Shut up! I'm watching!
Dewey: You shut up! I want more chips!
Reese: Here!
[After Reese throws the chips in Dewey's face, pottery breaks as Dewey lunges at him]
