Avatar the Last Airbender is my favorite show, i have to many to list, i think everything they say are my favorite quotes so i shall list some of them :)
Sokka: My first girlfriend turned into the moon
Zuko: That's rough, buddy.
Zuko: What would uncle say? Sometimes, clouds have two sides...a dark and light and a silver lining in between, it's like a silver sandwich! Sooo...when life seems down, take a bite out of the sandwich..?
Sokka: Hey! Maybe we haven't failed after all!
Zuko: That's the spirit!, I can't believe that worked, I didn't even know what I was saying.
Sokka: No, what you said made no sense at all, but look! Suki!
Zuko : How am I supposed to convince these people I'm on their side?! What would Uncle do? Zuko, you have to look within yourself, to save yourself from your other self...only then will your true self reveal itself ... Even when I'm talking for him I can't figure out what he means!
Toph: I'm beginning to wonder who is really the blind one all around here
Zuko: Think again! I am going to speak my mind, and you are going to listen.
Aang: Wow. I haven't cleaned my room in a hundred years. Not looking forward to that.
Katara: Observe... the ancient art of penguin catching
Iroh: There is nothing wrong with letting people who love you help you. Not that I love you.. I just met you
and i am soo exited for the new spin off series i cant wait, i swear i check avatar wiki everyday to see if there is any more information on it.
