The Legend of Korra, Season 1

Tahno:
Well, well, well, if it isn't the Fire Ferrets. Probending's saddest excuse for a team. Tell me, how'd a couple of amateurs like you luck their way into the tournament? Especially you, uh-vatar. You know, if you'd like to learn how a real pro bends, I could give you some private lessons.

Korra:
You wanna go toe to toe with me, pretty boy?

Tahno:
Go for it. I'll give you the first shot.

Bolin:
Korra, don't. He's just trying to bait you. If you hit him, we're out of the tournament.

[Korra raises her hand making it seem like she's about to hit him square in the face. Suddenly, she whistles, causing Naga to burst through the window roaring right in Tahno's face. Startled and humiliated, Tahno quickly retreats]

Bolin:
I've never seen anyone rouse Tahno like that. You are one of a kind, Korra.
