Avatar: The Last Airbender, Season 2

Toph:
Well, no offense to you simple country folk, but a real society crowd would spot you from a mile away. You've got no manners.

Katara:
Excuse me? I've got no manners? You're not exactly lady fancy fingers.

Toph:
[burps] I learned proper society behavior and chose to leave it. You never learned anything. And frankly, it's a little too late.

Sokka:
Ah-Ha, but you learned it. You could teach us.

Aang:
Yeah, I'm mastering every element. How hard could manners be? [grabs a nearby curtain and drapes it around himself like a robe, and begins talking in a very sophisticated manner] Good evening, Mr. Sokka Watertribe. Ms. Katara Watertribe. Lord Momo of the Momo Dynasty, your Momo-ness.

Sokka:
[in a fancy accent] Avatar Aang how you do go on!

[Both of them take turns bowing then try to bow at the same time, but they knock each other's foreheads' together and fall backward]

Toph:
Katara might be able to pull it off, but you two would be lucky to pass as busboys.

Sokka:
But I feel so fancy!
