Hal: A man likes to be noticed when he walks in a room, Lois!
Lois: Boys, would you leave the room a minute so your father and I can talk?
Dewey: No!
Lois: Excuse me?
Dewey: I'm not leaving! You guys just chase us out whenever you want without even asking us! I'm getting tired of it! Watching TV is the only thing to do in this house that's actually fun! So you're left with two choices! You can either fight somewhere else or get us a TV for our room!
[cut to Dewey stood in the corner of the room facing the wall:]
Dewey: There's no reasoning with that woman.
Reese: [ditto] I thought you made some good points.
Malcolm: It doesn't matter, she doesn't listen anyway. It's like talking to a wall.
Reese: [chuckles] Hey, that's what we're doing.
