Sokka: What's wrong?
Ying: The baby is coming.
Sokka: What, now?! Can't you hold it in or something?
Katara: Sokka, calm down. I helped Gran-Gran deliver lots of babies back home.
Sokka: This isn't the same as delivering an arctic seal! This is a real human thing!
Katara: It's called a baby. And I helped her deliver plenty of those too.
