This is another hilarious episode as it focuses on one of the minor characters. This time it's Corneille. He's a frog teacher, which makes as much sense as any other character here. Elmore School is being sold out so Gumball and Darwin assist Corneille to win a fighting match. He claims to be a fighter. As usual, the way they mock tropes is great. We get to see a parody of a montage when it only shows one thing.
That is, Corneille just standing there reading. I love the bit where the piece of paper keeps hitting Gumball in the face and he ignores it, but it turns out it wasn't useful anyway. There must be a trope for that. We see Corneille's enemy is a guy that is literally made of fists. Well, his feet and head are fists. It's been said he tried fighting the entire country of Belgium. ****
