From: City of Walls and Secrets
Katara: I can't believe we've finally mad it to Bai Sing Sei in one piece!
Sokka: Don't jynx it we could still be attacked by the fire nation, or the city could be flooded!
Toph: Have you been hitting the cactus juice again?
Sokka: I'm just saying wierd things happen to us.
Then a fat guy sucking on a corn cob comes and sits between Toph and Sokka.
