D.W. and Arthur in “Unfinished Business”

[walks into his room] What kind of a game was this?

This is not a game. This is a scale model of a Bell X-1 Rocket Plane. The plane that broke the sound barrier.

The sound barrier must be pretty hard. [takes out some pieces] Because this plane is all smashed up.

Nope, it's not smashed. And I'm gonna build it. [yells to D.W. while snatching the pieces from her] Hey, stop touching everything! You'll mix up all the pieces!

I’ve never heard of toys that come already broken.

[while lividly, and relentlessly staring to D.W.] No, it's not!

[backs up from her brother] I'm going. Never say that I didn't go when you need me to go, because I'm going. Like this. [snaps her fingers] And the minute that you need me to go, I'm on my way out of there. No waiting.

[turns red, and yells] (Just) go already!

And if you say please, I go even faster. Because when...

[growls to D.W.] Grrr! [scornfully sends D.W. out of his room]
