Phineas: Can you turn the living room light on?
Carrie: Why?
Phineas: Because I want them on. That’s why.
Carrie: Fine. They’re on.
Phineas: Why did you turn the night-light on?! I didn’t ask for that!
Carrie: I didn’t.
Phineas: Yes you did. Why did you do it?!
Carrie: I did not turn them on.
Phineas: Well if you didn’t, then who did. Someone did!
Ezra: I did.
Phineas: WHY DID YOU DO THAT?! TO DRIVE ME CRAZY??
Ezra (giggling): Yeah! Why else would I do it?
