Harold: DIIIIIEEEE RAT!
Korra: I am not a rat, I am a dog.
Harold: Are you sure? You look exactly like a rat.
Korra: I am sure. See? I can growl.
Harold: So can I.
Korra: I am a dog. I swear. I can chase you if that will prove it.
Harold: That won't be necessary.
Korra: So? You believe me?
Harold: DIIIIIEEEE DOG!
