In the morning, Darwin is trying to wake up Gumball because they're late to school until Darwin slaps Gumball on the face and then Gumball wakes up. Then Darwin yells at Gumball saying that they are late for school, then Gumball tries to calm Darwin down and say he will be ready in two seconds and then Gumball went to their light switch and switch the light's off and then turn back on two seconds after and Darwin sees Gumball already change. Darwin ask Gumball how did he change so fast and then the answer is by using T'Chaka style, Darwin ask Gumball who is T'Chaka then Gumball answer "you know, that guy from that movie with a lot of cool stuff from Africa, and have his own secret district or country in Africa but then he died and let his son becomes the king of the district or country and his heir as that guy with the panther suit" then Darwin remember the movie he and Gumball watch at the cinema. Then Darwin snaps and drags Gumball outside and start to run with Darwin holding Gumball's hand and the both starting to yell at the school bus to stop but Rocky doesn't hear them, then Gumball's anger took control and Gumball picks up a rock and then throw it to the school bus window and the window break. Rocky stops the bus and Darwin and Gumball walks into the bus and sits down.
Gumball put on his earphones and hear some music in Spotify, Darwin asks what is Gumball hearing and Gumball replies "someone made a mix called 'Mix Keren (1940-1990)' and the word 'Keren' is not a typo from the word 'Karen' because if you translate it, the word 'Keren' means cool. So it translates into 'Cool Mix (1940-1990)' " Darwin got his answer and let Gumball hear his music and the music Gumball hearing is P.Y.T. by Michael Jackson then they arrive at school, and they went to their class. In the cafeteria, Gumball and Darwin were called by Mr. Small to see him at his office but in Mr. Small, there are Principal Brown sitting next to Mr. Small. Gumball and Darwin are confused about why the two of them are called to Mr. Small's office and Principal Brown tells them angrily about they were breaking the school bus which means the school property. Then Principal Brown asks if Gumball throws something to the school bus window but Gumball tells them the truth but then Mr. Small ask them to have an introduction if Mr. Small and Principal Brown are new teachers and then they have the introduction. Gumball asks who is Mr. Small but Mr. Small don't use his name but by "Yu" then Gumball says "not me, you?" Mr. Small answer "yes, I am Yu" Gumball starts to get frustrated "just answer the god dang it question, who are you?!" Gumball asks frustrated "I have told you" Mr. Small answer "are you deaf?!" Gumball asks "no, Yu is blind" answer by Mr. Small, then Gumball said "I'm not blind you blind" "that is what I just said," Mr. Small said, "you just said what?!" Gumball asks then Mr. Small answer "I didn't say what, I say Yu!" "that is what I asking you!" Gumball yell "the fact is that" "shut up!" Mr. Small stated until Gumball cuts him and Gumball asks pointing to Principal Brown and said "you!" then Mr. Small answer "yes?" "not you, him!" yell Gumball, Principal Brown answer "Mi" "yes you!" yells Gumball, then Principal Brown answer "I am Mi". Gumball looks confused and frustrated " his Mi, and I'm Yu," tells Mr. Small. Gumball anger takes control and starts to yell at the three of them "now I'm gonna whoop your ass man because I'm sick of playing games man. You, me, him, everybody asking around here, him!" Gumball was about to kick Mr. Small at the ass until Darwin holds his brother and try to calm him down.
Then after Gumball calm down, Mr. Small tells the purpose of the conversation it was about controlling anger and to see if children know a movie reference. "Gumball, you need to control your anger even if you get frustrated by the situation, just try to relax and find something to answer your problem without breaking any law or object. And the reference is from Rush Hour 3" then Principal Brown stood up and say to Gumball that he now has detention this afternoon after he broke school property and he will be accompanied by Principal Brown himself, and maybe another student who gets detention too. Then Gumball and Darwin get send to their class.
In the afternoon, Gumball is accompanied by Principal Brown and Darwin and Carrie because of Carrie who draw all the sketches on the school walls and Darwin because he was standing next to Carrie warning her before she got detention and then principal Brown and caught Carrie and think that Darwin also in the crime. Darwin and Carrie just talk and play hand games at the corner of the room while Gumball was hearing Gangsta Paradise by Coolio in the cool remix he found until he sees Sarah at detention staring at him, "what are you doing here, Sarah?" Gumball asks "nothing" Sarah replies "then why are you here?" Gumball asks again "I always stick around at your and Darwin's side at any place and any time whenever you guys are in detention or in space and I always know where are you guys because I love you two", Sarah answer and Gumball say "ok first that's not sticking around that's stalking...maybe I don't know, second that's creepy both of the stalking parts and I love you part, and third I suggest go right now" then principal Brown cames in ask Sarah "Mrs. Lato, what are you doing here?" "I-I have detention, principal Brown" Sarah replies. Principal Brown look suspiciosly to Sarah "well that's what you said" said principal Brown calmly, "don't stare at me and talk to me, ok" said Gumball while continuing hearing gangsta paradise.
After detention, Darwin and Carrie leaves and heading to the park for their night date while Gumball is walking to the school's front door until he hear's Penny voice calling his name while running to talk to him. Gumball stops walking and greeted Penny and kiss her, Gumball ask a Penny what's wrong and Penny answer with a sad tone "we need to talk".
