“Spend It Wisely”
Sokka: We got exactly three copper pieces left from the money King Bumi gave us. Let’s spend it wisely.
Aang: Make that two copper pieces Sokka. I couldn’t say no to this whistle.
(Aang blows the whistle which is silent)
Sokka: It doesn’t even work. See? Even Momo thinks it’s a piece of junk.
Katara: No offense Aang, but I’ll hold the money from now on.
