In gym class, Gumball is doing push-ups and a large amount of sweat was poured out of his sweater. Coach Russo then orders Jamie to do a cartwheel, and Jamie does it wonderfully. Gumball tries to do the cartwheel, but he does it so fast that he lands with a thud. Gumball does a trampoline to bounce higher, but ends up crashing up the ceiling.
At the school cafeteria, the tired and injured students complain about how hard it was in gym class. Jamie then bursts into the cafeteria, and orders the students to beat it, but Gumball still stood there. Jamie was about to hit Gumball in the face, but Coach Russo stopped her and made her apologize to Gumball. Jamie says she's sorry and she will be friends, which shocked him, and the rest of the students were shocked too.
The next day, with the students still shocked, Jamie encounters Gumball and Darwin. Gumball tries to convince to Jamie that she doesn't have to be a bully anymore, but Jamie shoves him in Darwin's mouth, and tells the classmates about the school going in history. Out of school, Gumball and Darwin discussed the moments of Jamie torturing the students. They then see Coach Russo and Jamie riding home in their car. Gumball and Darwin go after them.
After running and encountering a bunch of dogs along the way, they arrived at Jamie's house, where Jamie's car arrived home at the same time. Jamie's father welcomes them home. Coach Russo then reveals she is a woman, which shocks Gumball and Darwin again, ending the episode.
This is the second time Anton has been eaten by the ducks, the first being in "The Goons." This is also the first time he's been injured since Season 1.
This is the second time Taekwondo is mentioned, the first time was in "The Gi."
Gumball's internal organs are shown for the third time, the first time was in "The Bumpkin," and the second was in "The World."
This is the second time Carrie has blushed in the series, the first was in "Halloween."
This is the third time Gumball is in Darwin's mouth, the first two times were in "The Helmet" and "The Voice."
This is the second time Gumball gets frozen in cement. The first was in "The Third."
Coach tells Gumball and Darwin to cart-wheel "like a boss," a phrase which originates from Slim Thug's rap song "Like A Boss," later made popular by a parody of the song with the same name by The Lonely Island.
Coach's voice sounds similar to that of Roz from Monsters, Inc. Also, Gumball's brain talking mimics a professor on the news of the same movie.
Coach says she won gold for cartwheeling in the 1986 Olympics, even though they didn't have the Olympics in 1986. This could be because the show might be in another world.
In this episode, Gumball and Darwin say that it was Jamie who fed Anton to ducks, a reference to "The Goons," although in the actual episode, it's shown that he fell into the river by himself. She may have fed him to the ducks again at the same lake.
[Scene begins outside the infirmary, where Gumball and Darwin are there. Gumball knocks on the door]
Darwin: Are you sure this is gonna work? 'cause I really don't want to go to gym class. [Gumball kicks himself in the face]
Gumball: Ah! My legs are trying to kick my brain for just thinking about it. But don't you worry. Today's the day the plan works.
Darwin: But it's already gone wrong so many times. Maybe we should just accept our fate and go to gym class. [Gumball kicks Darwin's leg] OW!
Gumball: Don't say that word. You're making them angry. Just let me deal with this.
[Gumball knocks on the door again, and Joan answers]
Joan: What is it? No, I haven't lost weight. No, I haven't done something new with my hair. No, you don't have the Bubonic Plague. No, you can't have a second opinion on that, therefore, no, you cannot get a note to skip gym class. [Gumball kicks himself again] What was that?
Gumball: Don't worry about it. What's more important is that I respect you as a professional and I commend you for your dedication to medical practice. And for this, I would like to personally shake you by the hand.
[Joan opens her hand to find a coin]
Joan: Did you just give me a quarter?
Gumball: And there's plenty more where that came from. How does a thousand cents sound to you?
Darwin: Ten dollars?
Gumball: How does a hundred cents sound to you?
Joan: A dollar? [Writes a note] If I just wrote you a note now, would you promise never to come back?
Gumball: [Shakes Nurse's hand] I swear. [Runs away with Darwin]
[Joan opens her hand to reveal a slip of paper]
Joan: Hey, that's an I.O.U.
Gumball: [To Darwin] Told you it would work.
[Gumball and Darwin dance like cool kids through the hallway, but are then blocked by a mysterious, very large figure]
Coach: Why are you kids not in gym class?
Darwin: We've got a sick note.
Coach: Where is this sick note exactly?
[Gumball and Darwin manage to get off of Coach]
Gumball: [Points at Coach's shorts] I think it's in there somewhere.
Coach: How convenient. You don't look very sick to me. And you look at me in the eye when I'm talking to you.
Gumball: Uh... sure. Let me just take a step back. What the...? What's going on here? You don't seem to be getting any further away. Oh, there we go. Hi, mis...ter.
Coach: You can call me Coach. Now get to gym class.
[Gumball kicks himself in the face again]
[Scene opens inside Gumball's body, showing his heart beating quickly]
Heart: [Gaps twice] What's going on?
Lungs: I have no idea, but it's horrible!
Heart: Code Red! I repeat -- Code Red! This is not a drill! This body is exercising!
Stomach: Somebody do something!
Heart: Brain Dude! what do we do? I can feel myself getting healthier!
Brain: Well, in circumstances like this, I think it's safe to say that now would be the right time to... FREAK OUT!
[All of Gumball's organs start screaming, and Gumball gasps while sweat pours out of his body]
Jamie: Hey, Watterson, If your sweat reaches me, I'm gonna invite you to a pain party, where the only guests are you, me and my fist.
Gumball: It's not sweat. It's my organs crying.
Coach: Come on, Watterson. If you can't manage a simple push-up, how are you ever gonna do a cartwheel?
Gumball: Why would I ever want to do a cartwheel?
Coach: Because everything you learn in gym class could make a difference in your life one day.
Gumball: What possible use could I have for knowing how to do a cartwheel, apart from physically replacing the wheel on a cart?
Coach: Maybe the day you want to win gold in the '96 Olympics.
[Coach shows a photo of her upside down]
Darwin: That's not a cartwheel. That's just a photo of you upside down.
[Coach rotates her photo]
Gumball: Yeah, well, that still doesn't prove it's useful.
Coach: Oh, really? Jamie, you're running being chased by a pack of angry dogs, but oh, no, you've dropped your pen. [Drops pen on the floor] Now, do you let those dogs have that hard-earned pen, or do you cartwheel your way out of it like a boss?
[Jamie cartwheels to get the pen to the coach]
Gumball: Statistically, that is quite unlikely, but in that highly illogically and incredibly specific situation, I guess you do have a point. But what about that stuff?
Coach: Let me paint you a picture. You're being chased by another pack of angry dogs. You've reached a ravine with only asymmetric bars allowing you to reach the other side. They want your pen. What do you do?
Gumball: I guess I'd just turn on my jet pack, fly over the ravine, land in my flying car, and drive to space.
Coach: That's completely unrealistic. Jamie, come here and show Watterson how you would do it.
[Jamie rotates quickly]
Coach: Perfect. You remind me of me at your age.
Gumball: Except for the fact she has a neck.
[Gumball tries to rotate]
Coach: Faster. That's not how you take gold at the '96 Olympics.
[Coach rotates her photo]
[Gumball starts rotating, and drops his pants] Oooooh, man! Darwin! my pants!
Darwin: Try and go faster! Speed will blur your shame.
Gumball: I can't! I'm at full speed! Do something! Anything!
Darwin: Hold on! I'm gonna try and put them back on in three, two...
Darwin: How am I gonna eat? Coach worked all my muscle groups. Even my tongue hurts.
Anton: Coach told me I need to cut out the carbs. And that's all I am!
Alan: When Coach said they were gonna get us into shape, I never expected to look like this.
Carrie: That workout was horrible. I actually feel alive.
[The door of the school cafeteria opens suddenly, Jamie enters]
Jamie: If you don't get out of my way, you're gonna meet the new "Fistory" Teacher, Professor Knuckles, for a two-hour lesson of pain. Now move!
[Darwin, Carrie, Alan, Anton, and Rocky go, but Gumball does not go]
Jamie: What are you still doing here?
Gumball: To be honest, the pain from moving would be worse than the pain from your fists, so just go ahead.
[While Jamie will punch, Coach enters whistles]
Coach: The only type of fighting I tolerate is on the mat like when I won the gold medal in Tae Kwon do at the 1988 Olympics. [Coach...] Bandal Chagi. Dollyo Chagi. Yeop Chagi. Conan. [Coach returns Jamie] Jamie, you apologize to Watterson this instant.
Jamie: Yes, Coach. I-I'm sorry, Coach.
Coach: Now, what do we say to people we've upset?
Jamie: [To Gumball] I'm sorry, Gumball, for what I said. Let's put our differences to bed. I hope these words will make amends and we can be the best of friends.
[Gumball and the others are shocked, and their mouths open. The boys continue on with their day with their jaws still dropped]
The Next Day
Gumball: You apologized.
Jamie: Yeah, whatever. You better shut up if you don't want Mr. and Mrs. Pain to invite you to dinner. They only serve filet o'fist!
Gumball: It's okay, Jamie. You can left that anger go. You touched our hearts yesterday.
Jamie: Oh, I'll touch your heart...with my fist!
Gumball: That's...quite a vivid image, but understand you don't have to be a bully anymore. Coach saw what we were all too blind to see. That you're really a sweet, kind...orange thing with, uh, a hat or a wig or some kind of a helmet and horns that we're proud to call our friend.
[Jamie picks up Gumball and throws him into Darwin's mouth]
Jamie: I am not anyone's friend! The only friends I need are grandma and grandpa fist. And they don't give candy. I'm gonna show you! I'm gonna do something so bad, it'll go down in school history! [Storms off]
Gumball: [In Darwin's mouth] We're gonna have to work on Jamie's hugging technique.
[School bell rings, and everyone out of the school]
Gumball: You don't think Jamie's really gonna do anything bad, do you?
Darwin: Of course not. Just because she fed Anton to the ducks... [Flashback of Anton being eaten by ducks] ...or that she chewed Teri's own body to spit it back in her face... [Flashback of Teri] ...or that she ate a little bit of Sarah and Banana Joe. [Flashback of Sarah and Banana Joe]
Gumball: Dude, stop talking about it! I can't take any more horrible flashbacks!
Darwin: But people change. Just because she did all that doesn't mean she's capable of climbing into the back of a teacher's car to do something so bad that it'll go down in school history!
[Jamie enters Coach's car]
Darwin: Dude, we got to do something!
Gumball: Hold up! Let's try the easy way first. [Aloud] Coach! Coach! Coach!
[Darwin starts pushing Gumball. Coach continues driving, while singing along to a strange tune on the radio]
Darwin: No, we need a shortcut. There! [They come to a path that is recently cemented, the cement still wet, with scaffolding poles]
Gumball: [Spots Coach's car] There they go!
Darwin: All we got to do is get across that wet cement using those asymmetric scaffolding poles.
Gumball: But how?
[An image of the Coach appears]
Imaginary Coach: Because everything you learn in gym class can make a difference in your life one day.
Gumball: Coach, you've got to pull over. Jamie's in the back of your car, and she's about to do terrible things to...
Imaginary Coach: Kid, Im a vision, not a phone.
Gumball: Okay, just imagine there's a pack of dogs doing some stuffs and you've got to get to the other side of that.
[Gumball does an impressive feat of gymnastic, but still faceplants in the wet cement]
Darwin: Hurry up! We're losing him!
[Gumball running while being in cement]
Darwin: No, wait, they're slowing down! We're not losing them! No, wait, they're going faster again! We're losing them! Oh no, they slowed down again! They're turning the corner! They're driving up the street!... They're gone!
Gumball: [Break free of the cement covering him] How are we gonna find them now?
[Gumball and Darwin spot Tobias jumping on his trampoline. Gumball pulls it to the side while Tobias is coming down from the air, causing him to crash into his house.]
Darwin: I can't see them yet!
Gumball: There they are!
Gumball: Over there!
Darwin: I cant see where you're pointing!
Gumball: Just follow me! [Gumball bounces off the trampoline to the direction of Coach's car, then fall downs the road. He yells after Coach's car] Coach! Watch out! [Looks at Darwin] How come you look so good?
Darwin: I walked around the block. What kind of psycho jumps over three streets?
Gumball: Yeah, I was just in the moment, I guess.
Darwin: Come on! Let's cut through this backyard and catch them on the other side!
[They enter the backyard, where they see a pack of angry dogs]
Darwin: Angry dogs, and I've got a pen in my pocket. What do we do?
Gumball: We cartwheel out of here like a boss. [Gumball and Darwin do cartwheels]
Darwin: Okay, what do we do now?
Gumball: Just keep on cartwheeling.
[The Cube Dogs stop growling, confused at Gumball and Darwin's cartwheeling. They continue as the dogs clear the way and observe them curiously]
Gumball and Darwin: Yes.
Gumball: There they are! Jamie! Coach watch out! Jamie, no!
Mr. Russo: Hey hey hey! How's my beautiful wife and daughter? [He kisses Coach and Jamie on the cheek]
Gumball and Darwin: Coach is your mom!?
Mr. Russo: Isn't the resemblance obvious?
Jamie: What? You're shocked because mommy is now at school to keep me in check? You're shocked because no one have to be scared of me anymore and all I have is big talk? You're shocked because fist's license to punch is revoked as of now?
