Ivy: If you could break the sound barrier, falling out of a window won't be able to fix it.

Eric: I told you not to touch it!

Ivy: You built it all wrong! Did you even read the directions? It's not my fault if I made a plane that can't fly.

Eric: I told you not to touch it!

Ivy: Waaaaaaaaaaaaaaaaa!

Mom (offscreen): Eric Alexander Smith, come here!

Eric (guilty): Uh-oh! Middle name!

Ivy: Are they gonna have to ampu-take my arm?

Dad: No, honey, it's amputate, not ampu-take.

Ivy: They're gonna amputate!

Dad: No, I'm in charge and I'm putting ice on it.

Ivy: Ow!

Dad: What's wrong?

Ivy: That's cold!

Mom: Apologize to your sister.

Eric: No way! She should apologize to me. I worked all hard on this. I told her a million times not to touch it.

Ivy: You're bad!

Dad: Eric, this means no TV for a week.

Eric: What? That's so not fair! You won't even deal with for what she did to me!

Mom: We'll deal with for what she did. For what you did is wrong, too.
