Trivia

 * These shorts feature the Japanese voice actors from the anime in their respective roles

Eren over-sleeping, causing him to be late and get mad at Mikasa/Armin for not waking him up
 * There are a lot of running gags throughout episodes:

Members on the cast getting eaten by the Colossal Titan at the end of each episode (with Eren almost constantly being one of them,usually making excuses to why he got eaten) and then arguing as they slowly sink

Mikasa never making facial expresions, changing her tone or showing any emotions at all

Keith getting mad at one of the cadets and telling them to come to his room later

Mikasa showing feeling for Eren,only to be turned down by him

Armin being a big pervert The first day of training when they got intimidated by Keith Shadis
 * Characters always pronounce sounds or small movements they make (ex. saying chung* chung* when the bell is ringing, wipe* when they are wiping tears, saying raise* while raising their hand, or dot* dot* dot* ding* while thinking)
 * There are a lot of references to anime episodes of the series:

Jean getting captivated by Mikasa and her long black hair, developing rivalry with Eren

Mikasa cutting her hair,saying how "the world is a cruel place" (but for a comedic effect), shoving a loaf of bread into Eren's mouth, telling others how she is way stronger than them

Sasha stealing meat and can always be seen eating a potato

Armin bringing a book and reading it with Eren, later mentioning "burning water, frozen earth, fields of sand" (although in different context)

Levi Ackerman dressed up in cleaning outfit and carrying a mop, "taking cleaning very seriously"
