At Toki's Recital, when Skwisgaar interrupts Toki's demonstration, Nestor Kirchner (former president of Argentina) can be seen sitting behind him. This is the second time Nestor Kirchner has appeared in the show (his first appearance was in Dethkids).
This is the first appearance of Vater Orlaag.
Ofdensen: As you all may have noticed, Toki is concerned about his role in the band.
Nathan: He plays...rhythm guitar right?
Ofdensen: Right Nathan.
Pickles: He barely even plays.
Nathan: He makes sandwiches.
Murderface: I make sandwiches.
Nathan: WHOA! That guy does nothing around here.
Murderface: I've said it before, and I'll say it again: Voting sucks.
Pickles: I was actually president of the official Voting Sucks Club in high school.
Nathan: Oh, really, how'd that go?
Pickles: Well, I wasn't re-elected.
Nathan: You know it!

Murderface references the comedian Larry the Cable Guy by quoting his catch phrase "Git-R-Done!"
