The episode begins with Gumball and Darwin studying for their math test, but, they get bored easily, so they start playing, distracting them from studying. The next day, they complain about how they should have studied last night while eating pages off of books to "absorb the information." But then, they realize that they are eating the pages of the wrong book. Since they only have 10 minutes, they both decide to cheat by writing facts on Darwin's face.
Later, they end up in Principal Brown's office, resulting in a Spring break detention. In the detention room, Gumball and Darwin try to talk to each other in secrecy, but, it's revealed that they're actually saying what they were thinking out loud, leading to the duo getting beaten up by the detention "inmates." Gumball and Darwin then decide they must look older in order to get the respect from the detention inmates by drawing fake facial hair with markers, but, it ends up with Gumball getting his face squeezed by the Pink Bear after offending him. The Bomb Guy demands Pink Bear to stop, Gumball then thanks him, and says he owes him one, but the Bomb Guy replies, "You're gonna owe me a lot more than that if you want my protection."
Gumball and Darwin are then seen cleaning Brown's room. When Miss Simian closes the door, Gumball and Darwin then open all the cabinets in Brown's desk and find the school plans which the Bomb Guy wants Gumball and Darwin to steal. They are then distracted by Brown's calendar, and get caught, resulting them in a trip to the "Correctional Room." The detention song then plays, showing the duo stealing a paper clip, spoons, a rake, and a rope for the Bomb Guy. The song ends with chaos in the detention room, causing Brown to burst in there, giving the Bomb Guy a chance to escape with the stolen items.
The duo follows the Bomb Guy, and ask if they can escape with him, which he refuses. While the Bomb Guy is inside the vent, Gumball jumps on him, causing the vent floor to fall to the side, revealing they are above Brown's office. The Bomb Guy allows them to escape together with him so that Gumball and Darwin can help him up, but, they accidentally awaken Brown, who announces on the speakers that there is a detention break. The 3 escapees go up to the rooftop inside the vent, but, they find themselves stuck, as the rooftop vent cannot be opened. Gumball then angers the Bomb Guy, causing his fuse to go off without him knowing, and they escape down in time for him to go off and explode the vent. His last words are "Well played."
The duo then figure out the rake and the rope are supposed to be used for a grapple hook, but, it requires math to be used, and they fail, causing the hook to break one of the windows in the school. Brown then arrives at the roof, and Gumball and Darwin attempt to jump off and land on a vehicle, but, they miss, and fall on the cement. They then laugh at Brown saying that they have escaped. The episode ends with Brown saying "I don't know why they are so happy, they still have to come back here tomorrow."
Gumball states that they are in the seventh grade, despite Miss Simian having been described as a second grade teacher - this is because the schooling systems in the US differ from the UK (in the UK, second grade of secondary school is equivalent to seventh grade in the US).
This also gets Darwin a second detention with Gumball. The first happened in "The End."
The ending scene, where Gumball and Darwin jump off the roof rather than get caught by Principal Brown, may be a reference to the ending scene of the film "Thelma & Louise", where they also jump from a large height rather be captured by authorities.
It could also be a reference to a scene from the film "The Other Guys", where Christopher Danson and P.K. Highsmith died after a failed leap attack.
Gumball and Darwin act out scenes from several different movies in the beginning.
Star Wars Episode V: The Empire Strikes Back: After Darwin fails to answer his question, in Darth Vader's voice, Gumball zaps Darwin with imaginary force lightning as he says "You have failed me for the last time..."
[The event begins with Gumball and Darwin reading math books, attempting to study for an upcoming math test. Gumball starts roleplaying, and Darwin roleplays along. Gumball grabs his ruler, and in slow motion attempts to attack Darwin. Darwin quickly grabs a triangular ruler and acting like he stabbed Gumball. Gumball, acting like he is stabbed, grabs a calculator and presses buttons, acting like he is using a remote to activate a bomb]
Gumball: Noooooo! [Activates bomb]
Gumball and Darwin: It's gonna explooooooode! [Explosion sound][Snaps out of it]
Gumball: Oh, come on. Concentrate a little, man. We'll never be ready for the math test.
[Darwin sighs, and they go back to reading]
Gumball: [Strange voice while reading] If zhe square of zhe hypotenuse equals zhe sum of zhe square of the other two sides, vhat is the length of side A?
Darwin: [Strange voice while acting like Igor] I know not, master.
Gumball: [Throws down book] You failed me for the last time. ["Zaps" Darwin, who starts yelling. Then snaps out of it once again] Oh come on, we're supposed to be studying.
[Both start reading again, but then Gumball starts playing music with his ruler, and Darwin starts slamming his book in harmony until Gumball interferes again]
Gumball: Dude, stop distracting me! [Reads book again] Alright, let's get some work done.
[Scene cuts to them playing around. First, they shoot spitballs at each other while hiding behind chairs. Then Gumball puts a pencil through one of his nostrils, and it comes out of his ear. After that, Gumball spins Darwin around in an office chair, and stops with Darwin's tail in his mouth. Gumball puts a pencil through a nostril again, and it comes out of Darwin's nose. Then they duel each other with geometry compasses. Darwin puts a pencil through his nostril nose, and it comes out of Gumball's ears. Then it shows their house at night. Off screen, they are heard laughing out loud]
Almost Time For The Test!
[Gumball and Darwin are seen crying out loud, and chewing the pages of books]
Gumball: [Crying] It's not working, I'm not absorbing any of the knowledge.
Darwin: [In Spanish] Why didn't we study when we had the time?
Gumball: [In Elizabethian English] Be still, you cur. (Chill out dude.) Imbibe thy portions swiftly. (Keep chewing.) Anon we face our trial. (We only have ten minutes until the test!) By my by!? (What the what?!) [Closes his book] Elizabethan poetry? Fie and fie again! We've been chewing the wrong books!
[Darwin spits up some chewed pages, and puts it back on his book]
Gumball: Ahh! We're gonna flunk the test. We'll get caught in a downward spiral of failure, we'll get held back a year and before you know it, we'll be the only kids in seventh grade with beards.
Darwin: We could [Whistles]
Darwin: You know, we could [Makes a noise with his tongue]
Darwin: You know, we could [Darwin makes more noises]
Gumball: [Gasps] What?! You mean-
Nigel Brown: CHEATING!? Did you really think you could get away with this?
[Turns to Gumball and Darwin, with writings including math solutions all over Darwin's body]
Gumball: To be honest, yeah. I thought we could. I have no idea what went wrong.
Nigel Brown: Well, maybe you'll figure it out during spring break which you're spending in DETENTION!
Nigel Brown: I'm putting you in the long detention block. So from now on you don't eat, you don't go to the bathroom, you don't speak, you don't even blink unless I say so. DO YOU UNDERSTAND?
[Darwin raises his hand]
Nigel Brown: What?
Darwin: Can I blink please?
Nigel Brown: No.
The New Inmates
[They enter a classroom full of "delinquents." The delinquents make noise, and trash the room]
Nigel Brown: SILENCE YOU ANIMALS! These are the new inmates. Make sure they feel welcome.
Darwin: [With dried eyes] Can I blink now?
Nigel Brown: You're not gonna last two minutes in here, little fish.
[Principal Brown exits, and slams the door. Gumball and Darwin turn around at their new "inmates," looking scared. They start talking with each other seemingly through their thoughts]
Darwin: Gumball. Can you hear me?
Gumball: Yeah. What will we do? These ugly filths look like they were raised by hyenas in a post-apocalyptic future.
Darwin: Ha ha! Especially the cupcake. She looks like she was made out of rotten eggs, and foot fungus.
Rotten Cupcake: I'm a boy, dork bag.
Gumball: Ugh! Even her voice is gross. Wait-hang on. How come she hear our secret thoughts?
Hand: 'Cause you're taking out loud, homie.
Gumball: Yeah that makes more sense.
In The Bathroom
[Gumball and Darwin look badly injured after getting beaten up by their inmates]
Gumball: [Groans] Ow!! Oh man.
Darwin: [Pops out eye] Even my bruises have bruises.
Gumball: Don't worry buddy. I've got just what you need.
Darwin: A kiss to make it better?
Gumball: No. We need to look older if you want them to respect us. [Brings out marker] Lets get some tattoos, home boy! [They walk outside the bathroom with drawn on hair on their heads] What do you think?
Darwin: I don't know. I think we look a bit too old for young offenders.
Gumball: Maybe. [They walk back in. Then they exit again with more fake hair drawn on their heads] Perfect!
In The Cafeteria
[The delinquents are in the cafeteria eating, when Gumball and Darwin approach them and slam their lunches on the table. The delinquents glare at Gumball and Darwin. Gumball eats a piece of Pink Bear's food]
Gumball: What are you looking at, punk? [Gets brutally attacked by Pink Bear]
Darwin: Dude. Stop! His eyes are touching each other! Please let him go!
Bomb Guy: Enough! [Pink Bear lets go of Gumball]
Gumball: Oh! Thanks man. I owe you one.
Bomb Guy: You owe me more than that if you want my protection, daby.
Gumball: Whats a daby?
Darwin: Detention slang. For "dumb baby."
Gumball: Oh I see. Who protect us from?
Bomb Guy: [Raises eyebrow in confusion]
Darwin: He means "Who are you gonna protect us from?"
Bomb Guy: [Fuse lights] Me!
Stealing School Plans
[Gumball and Darwin are seen cleaning the principal's office]
Darwin: Why does that kid want us to steal the school plans anyway?
Gumball: That's the least of our worries. The guy's a walking time bomb.
[Gumball looks out the open door, and sees Principal Brown and Ms. Simian about to make out. Ms. Simian notices Gumball staring, and she blocks Gumball's sight with the door not closed though, but ajar]
Gumball: Okay. Let's do this.
[They rummage through Brown's desk]
Gumball: Here. Found it! Now lets get out of- [Starts chuckling]
Gumball: Dude, you have to see this. [Chuckles]
[They start looking at photos of Principal Brown, and they both laugh. After a while, Gumball puts the photos down and sees Principal Brown posing in the same manner as he is in the last photo and Ms. Simian in front of them. They quickly put back the photos, and Miss Simian sees them]
Lucy Simian: Ooooh! [Glares at Gumball and Darwin]
Gumball: It's not what it looks like. W-we accidentally slipped, and-and fell. T-t-the door went whoosh, and this went whoosh and we-let me start again. There was an eagle, and it came through the window and tried to steal-uh-I mean…it was totally like this when we got here.
Nigel Brown: I'll teach you for ruining my surprise for Miss Simian. You're both going to the correctional room!
Gumball: NOOOO! NOT THE CORRECTIONAL ROOM!
Mister Small: Boys. I believe you keep getting into trouble because you're not expressing yourselves creatively. To teach you how, I'm going to read you some of my poems, okay?
Gumball: I don't know why I freaked out so much. This really isn't that bad.
Mister Small: [Brings out super thick book] The first is an epic life story written from the perspective of a shoe. [Clears throat] Part one of eighty-seven: Birth …dark…factory…noise. The smell of polish...soles fitting soles soullessly, dolefully.
[Gumball and Darwin cringe in boredom. They bang on the office door's window]
Gumball: Let us out!!! This is cruel, and unusual!!
Planning To Escape From Detention
[Gumball and Darwin approach Bomb Guy in the classroom, traumatized]
Bomb Guy: So, what have we learn today?
Darwin: Don't…ever…break the rules…ever…again.
Bomb Guy: No fish, don't ever get caught. That's the only rule you need to care about. Now, here's a list of stuff you're gonna steal for me.
[Gumball inspects the list. Then the scene transitions into a song with a montage of them stealing the things on the list]
Gumball: [Singing]Well, I cheated on a math test, teacher says I gotta pay. Doin' time up at the schoolhouse, and it gets worse everyday.
[In a line heading to the classroom, Gumball "accidentally" knocks over the nearby principal's papers. He quickly and nervously recovers them, and gives them back. In the classroom, it is revealed that he had taken the first item on the list: a paperclip. In yet another line, Darwin comes through a metal detector]
Darwin: I've done a lot of bad things, as freedom wilted away. I've seen a lot of sad things, and it gets worse everyday!
[He walks to Bomb Guy playing a harmonica. Taking off his leg, he dumps out of it a couple of spoons the second item on the list. Then they our out in the field, working with rakes]
Gumball and Darwin: I never was a bad guy, 'til I was put away. Now I'm stealin', cheatin', lyin', and it gets worse everyday!
[One of the delinquents' the Rat's rakes are taken. Rat suspects Gumball who has the rake hidden in his head, but Gumball points to the rotten cupcake. The Rat attacks the cupcake instead. Then in the corridors, Bomb Guy receives the rake. Both Gumball and Darwin with the Pink Bear work out in the schoolyard. Gumball pretends to stretch, and grabs a string from the Pink Bear. He and Darwin walk way and unravel the string along, causing the Pink Bear's stuffing to come out, and him to be squished by a barbell. They give the string to Bomb Guy]
Gumball and Darwin: They think I learned my lesson, that crime just doesn't pay. But stuck here in detention, I have found another way. I'm the baddest kid in the prison…and I get worse everydaaay!
[Once again, the inmates trash the classroom. Principal Brown barges in]
Nigel Brown: SILENCE YOU ANIMALS! I WANT THIS ROOM CLEANED UP BY LUNCH TIME, YOU HEAR ME!?
[Behind him, Bomb Guy with all the materials given to him sneaks away]
Gumball: Where is he going?
Darwin: [Singing]I don't know why did he need a map, some rope, or a rake, and paper clip-[Stops singing and realized] Oh my gosh he's going to ESCAPE!
Gumball: No, dude. We are.
[They run out of the classroom, and through the hallways]
Darwin: I don't think we're ready for life on the outside.
Gumball: Why do you say that?
Darwin: Because we've run straight back to detention.
Gumball: I think we've been here so long we've lost our taste for freedom.
Darwin: Let's just go back in.
[They look inside the infernal chaos inside the classroom. Rotten Cupcake is threatened by Pink Bear]
Rotten Cupcake No, no, NO!
[Pink Bear brutally attacks him, and pops his cherry. The cherry juice splats on the classroom door's window in front of the boys]
Gumball: [Looking terrified] Did you see what that bear just did to that guy's cherry?
Darwin: I think that just cured me.
Gumball: LET'S GET OUT OF HERE!
[They run to Bomb Guy unlocking janitor's closet]
Gumball and Darwin: Take us!
Bomb Guy: Ha! I don't think so. [Throws a paper clip at Gumball. It bounces off harmlessly]
[Bomb Guy starts removing the screws off a ventilation cover]
Gumball: Dude come on, please!
Gumball and Darwin: We're too cute for detention.
Bomb Guy: I don't care. [Enters vent]
Gumball: [Tackles Bomb Guy] PLEASE, I BEG YOU. PLEASE!
[Gumball repeatedly bangs Bomb Guy on the vent until it gives way. They both fall into Principal Brown's office. However, Gumball holds on to the ceiling, and the principal is asleep]
Bomb Guy: [Not actually talking] Help!
Darwin: [Not actually talking] Depends, can we come with you?
Bomb Guy: Never.
Darwin: Take us with you or you're going down (very small text)
Bomb Guy: Sorry, what did you just say?
Darwin: TAKE US WITH YOU, OR YOU'RE GOING DOWN!
Bomb Guy: [Actually talking] OKAY, OKAY. JUST STOP SHOUTING!
[Principal Brown wakes up, and sees them. Bomb Guy unintentionally kicks Brown in the face as he is brought up]
Bomb Guy: Okay, we climb on this shaft to get to the roof.
Gumball: Are you sure? I mean this doesn't feel dangerous enough. Isn't there a lake of fire on your map, or maybe a spider pit? Oh, I know: how about an acid bath full of sharks with machine guns!?
Darwin: Don't worry, I've got this.
[He grabs the rake, and attempts to place it on the fan. It gets shredded to half its length]
Gumball: Wha- So, what's the plan now?
Bomb Guy: Well you can always go back!
[Gumball considers this. Then it skips to him climbing the noisy ventilation shaft. He talks, but the shaft drowns his voice out. He meets up with Darwin and Bomb Guy up in a compartment on the roof]
Gumball: Not as easy as I thought, so what now?
[He realizes that they are sulking. The compartment they are in has no way out]
Gumball: What the what!? I thought you said this led to the roof!
Bomb Guy: It does. It just won't open.
Gumball: [Enraged] What the whating what!? What do you mean it won't open!?
Bomb Guy: [Fuses light and incensed] I mean there's no way to get out of here, you masork!
Gumball: What does that even mean?
Darwin: Detention slang for "massive dork."
Gumball: [Scoffs] Oh yeah? Well you're a sodging derk with a fart-stache!
Bomb Guy: What?
Darwin: A soap-dodging thunder jerk with a fart mustache.
Bomb Guy: Yeah!? Well you're a serjenerf- [Continues making up detention slangs]
[While Bomb Guy makes up insults, Gumball takes Darwin and takes cover out of the compartment while Bomb Guy's fuse shortens. Bomb Guy notices, but it is too late]
Bomb Guy: You double-crossing ner- [Explodes]
[The compartment is finally breached. Gumball and Darwin laugh. They see Bomb Guy's body, and his deflated head]
Bomb Guy: [High pitched] Well played.
Gumball: I learned from the best.
[Gumball takes out a paper. There is a drawing of a person sliding down to the ground through a string tied to the roof, and the rake hooked on to an object]
Darwin: Oh, so that's what we needed the rope for. And we use the rake as a hooked!
[Gumball ties the string to a doodad on the roof. Principal Brown still imitating a prison siren can be heard]
Gumball: Uh, okay. How long does this rope need to be?
Darwin: Um it's the square of the height of the school, multiplied by-
Gumball: Are you sure it's not divide?
Darwin: Oh yeah. The square root of the height of the school minus-
Darwin: That's what I said!
Gumball: You said minus!
Darwin: It's the same thing!
Gumball: No, it's not! Is it?
[Banging can be heard at a door on the roof]
Gumball: Ahhh! Let's just wing it.
[He ties the string to the rake. Throwing the rake off the roof, it falls down short and breaks a window]
Gumball: Wish'd we'd done that math thing now. We could have escaped from detention.
Darwin: No dude. If we learned it, we wouldn't be in detention.
Gumball: Wow. I guess we did learn something today.
Darwin: When you cheat, the only person you're really cheating is yourself.
Gumball: Uh no. [Sees approaching van][Grabs Darwin's fin] Never get caught!
[They jump off the roof. Principal Brown barges in]
Nigel Brown: SURRENDER NOW and you'll only- [Gasps] Nooooo!
[In slow motion, Gumball and Darwin fall down. They slowly come nearer the roof of the van. Then no longer in slow-motion, the van speeds off and the boys instead hit the ground. They get up, disfigured by their fall. Despite this, they laugh]
Gumball: See you never!
Darwin: See you never, Principal Brown!
[They celebrate as they walk off. The principal watches them from the rooftop]
Nigel Brown: I don't know why they're so happy. They still have to come back here tomorrow.
