Carlos, Principal Valenzuela and others in “Unfinished Business”

[getting a call from Principal Valenzuela] Hey, Principal Valenzuela. [Frida gasps in excitement to hear the upcoming news] Are you calling to tell us what a good job we did with Carl?

No! He's somehow worse than before! He tricked the teachers out of giving him tests for the rest of the year! He also keeps calling everyone pawns and saying "checkmate".

[gasps in horror] Carl's now using chess to trick people!

[starts to sob] Oh, no. I'm so sorry, Principal Valenzuela!

Actually, it's "Hall Monitor" Valenzuela. Carl tricked me out of my job. He's the principal now!

[comes out of the office] Hey, Valenzuela, quit dawdling. That hall's not gonna monitor itself.

[growls] Argh! FIX THIS!

Ooh. I've created a monster. [looks at the chess board and gets an idea] There's only one thing to do - we have to beat Carl at his own game.
