Aang: Yo momma's so stupid, she got hit by a parked car!
Zuko: Your mother is so fat she jumped into the air and got stuck!
[Music cuts. Crowd fallls silent]
Aang: Yo momma's so stupid that when the doctor showed her a picture of her own feet, she couldn't identify them!
Music coming from out of no where as fireballs are being shot at Aang, Sokka, and Katara: Goodness, gracious, great balls of fire!
Aang: Get that cheap *beep* OUTTA HERE
Sokka: (about Zhao who is about to try to kill the Moon Spirit) It looks like he's trying to burn fish. I wonder if he's gay

Zuko: I'm not, they were free gifts from Burger King
Azula: [After winning a game of beach volleyball/"Kuai Ball"] Yes! We defeated you for all time. You will never rise from the ashes of your shame and humiliation! [Pause] Well, That was fun.

Aang: Seriously, Zuko. I have to go! Can I please be excused from today's lessons?
Zuko: I don't know, Aang did you ask Mr. Puppet?
Aang: I DON'T WANNA ASK MR. PUPPET! I'M ASKING YOU!
Zuko: Oh, I think you should ask Mr. Puppet.
Aang: Mr. Puppet, may I please be excused from today's lessons?
Mr. Puppet: Well, Aang, NO! NO, NO. NO! YOU GO TO HELL! YOU GO TO HELL AND YOU DIE!

Aang: *beep* Mr. Puppet.
Zuko: No, no, no. *beep* you.
