"Toph: Hey, wanna know what fireworks are like for me? Close your eyes.
 * Toph and the Gaang are watching a fireworks show while riding on Appa's back.

[Sokka does so]

Toph: [shouting in Sokka's ear] BOOM!!!

Sokka: O_O"

"Sokka: Good thing you listened to her, folks! I was about to bust out Mr. Boomerang! Whack-a-pow!
 * The three students at Toph's metalbending academy have some pretty funny lines between them. "The city's probably doomed! We're probably doomed!" "I hate doom."
 * Sokka's fantastic Moment Killer scene when he walks in on Aang and Katara's passionate kiss, and constantly referring to them as "oogie" afterwards, much to Katara's annoyance.
 * Even better, the moment that he killed was originally the last scene of the series, and an extremely emotional one at that. Hilarious.
 * After Toph stops the Earth Kingdom rioters:

Random Guy: Ooooh! "Mr. Boomerang"! Soooo scary!

(Sokka hits guy in the head with "Mr. Boomerang")"

"Sokka: You have to not only see the metal. But hear the metal. Taste the metal. And BE the metal!"
 * Let's not forget when, at the end of the comic, Toph licks Katara on the hand to demonstrate what "oogies" are.
 * Plenty of moments when Sokka assists Toph's Metalbending class.
 * And a Spongebob reference much?
