Aang: I'm tired so I think I'll go to sleep before our fight with the firelord.
Katara: That's a good idea, just go to sleep.
Katara: That's right, Aang, sleep well. Enjoy your last bit of rest as a human.
Toph: For when you wake up, we'll have been finished rebuilding you as the first cyborg Avatar. More machine than man and completely deadly.
Sokka: It's going to be totally sweet!!!
(Maniacal laughter ensues)
Aang: uh guys, I'm still awake.
