The episode starts with the Wattersons visiting Elmore Junior High on a Saturday. Gumball asks why they are there, so Richard excitedly explains that Saturday is club day. He happily rushes off to his Fantasy Club and leaves Gumball with Nicole.
Gumball asks his mother if he could join her club, but she explains that she becomes a different person when she is in her Anger Management Club. Mr. Small, who appears to run the club, greets her, but she suddenly lashes out at him for no reason and sends him flying through the door, knocking him unconscious.
Gumball then attempts to join Anais' Physics Club, but Anais denies him entry due to his lack of intelligence. Darwin offers Gumball a chance to be in his Synchronized Swimming Club. However, due to the fact that Gumball cannot swim, Darwin and the others have to deny him entry for his own safety (which Gumball acknowledges is probably for the best).
Gumball tries joining the Football Club with Banana Joe and Tobias, but the club only consists of them hitting each other with wet towels, taking showers, acting sporty and high-fiving each other. Hector, who is on the actual football team, comes into the locker room and tells them that their team lost, after which he strikes them with a massive towel. Gumball then tries to start his own club, which consists of only him. It does not work out, so he disbands it.
Later in the school corridor, Gumball has completely lost hope of being accepted into a club. Suddenly, the hallway goes dark and ominous voices appear out of nowhere offering Gumball a chance to join their club. It turns out that the voices belonged to the Rejects Club, a club consisting of nerdy social rejects Colin,Felix, Bobert, and Ocho. They desperately plead Gumball to join their club, but he declines, claiming he is desperate but not that desperate. After he leaves, the club vows to get revenge against Gumball.
That night, Gumball and his family are sitting down at dinner when a brick crashes through their window with a DVD attached. The family sits in fear as the DVD explains that the Rejects Club has developed a shoddily made "embarrassing" video of Gumball's school record and they are planning to send it around the school as revenge for not joining their club.
Gumball and his family then go to the school library to stop the Reject Club from uploading the video. At the door, they find that the door is locked so Nicole asks someone to make her mad and uses the resulting rage to break the door; however, she then tells everyone to proceed without her as she is still furious. As Richard and the kids rush into the library, Felix ambushes them, to which Richard retaliates by having a wizard battle. Bobert ambushes the kids soon after and transforms into his combat mode. Anais begins to generate static electricity by rapidly rubbing her feet on the ground and short-circuits Bobert with a single touch of her finger. Just before Darwin and Gumball reach the computers, they see that Colin is there, guarding the computer. Darwin proceeds to create a diversion by dancing, which eventually compels Colin to synchronize and join in the dance. Gumball approaches the computer but as he tries to stop the upload, Ocho comes and grabs his head, which prevents Gumball from canceling the upload.
As Gumball and his family drive home after the ordeal, Anais reveals that she was able to reroute all the videos before they could get to anyone, thereby saving Gumball's reputation (for now at least). It also turns out that the family managed to catch the entire Reject Club (with the group bound and gagged) and discuss how to punish them. Nicole notes that the "responsible" thing to do would be drive the Reject Club members home, explain to their parents what they did and let their parents punish them (which the club members object to). Darwin suggests coating them in honey and dropping them off in the bear cage at the zoo (which they also object to). Gumball then suggests dropping them off naked at the mall, which they agree to, ending the episode.
This is the first time that Tobias is seen not wearing his headband.
This is the first time Tobias and Penny are seen without their shoes.
Richard claims that he taped a wrestling match over a video of his and Nicole's wedding. However, it is unknown if this actually true, as Richard could have just made that up to make Nicole angry enough to break the door down.
This is Colin and Felix's first major role in an episode.
It is revealed in this episode that Gumball's middle name is "Tristopher".
Richard's Cottontail Cavalier cape from "The Gi" reappears in this episode.
This was the second appearance of Bobert's combat mode, the first being in "The Robot."
This was the second time Nicole angrily punches a hole in a door, the first being in "The DVD."
Colin and Felix's "shield of Zanthor" references James Lamont's persona, David Zanthor, hobo magician.
Colin swinging the broom like a lightsaber is a reference to the viral video "Star Wars kid," as well as to the Star Wars franchise as a whole.
The battle between Richard and Felix is full of references to Dungeons and Dragons, a popular fantasy tabletop roleplaying game, such as the attack "Magic Missile" and the dice rolling to determine the success of an action.
In Splash Master, players can perform a swan dive, which is most likely based on Gumball's dive in this episode. Also, one of Gumball's Nano powers in the Cartoon Network MMORPG, FusionFall, is a double-jump called the "Swan Dive of Eternal Beauty" that is based off the same dive that appears in this episode.
The theme song that Colin, Felix, Bobert, and Ocho sing when they prepare to go to the library is a parody of the Batman theme song used for the 1960s show. Colin shouting "To the nerd-mobile!" is another reference to Batman and the titular character's line of "To the Batmobile!"
Richard saying that he taped a wrestling match over his and Nicole's wedding is a possible reference to an episode of the 1996 show, Everybody Loves Raymond.
The music that plays on the radio during Colin and Darwin's dance is from the second Allegro movement of Antonio Vivaldi's Sonata for Oboe/Violin and Basso Continuo, RV 34.
Gumball's whisker goes through his head at one point.
When Nicole breaks a locker, her mouth is colored wrong. The same error occurred in "The Date."
When Hector swings the towel, a part of it is not colored in.
After Gumball jumps into the swimming pool, Penny appears to not have arms.
Gumball is shown and stated not to be able to swim at all, even though he was shown to swim very well in "The Responsible" and was able to get himself out of a similarly painful dive in "The Pressure."

Richard: [Panting] Come on, you guys! We're gonna be late!
Gumball: Remind me again why exactly we're at school on a Saturday.
Richard: Are you kidding me? It's club day. It's the only day of the week when I get to hang out with people I really like.
Gumball, Darwin, Nicole, and Anais: [Angrily] What?!
Richard: Uhh... Got to go!
Nicole: Okay... See you all back here at five.
Gumball: But wait! I don't have a club to go to!
[Nicole starts walking to her club but Gumball stops her]
Gumball: Well, Mom, looks like it's your lucky day. I'm coming with you to your anger-management club.
Nicole: Oh, that's sweet, Gumball, but behind this door, I'm a very different person. Trust me, you don't want to see this. [Enters the room]
Mister Small: Hello, Nicole, welcome to— Aaach! [Flies out of the room] Uuuuuh. [Passes out]
Anais: [Opens the door on the opposite] Could you guys keep it down a little?
Nicole: You keep it down!
Gumball: Hey, Anais. What club are you in?
Anais: Physics club.
Gumball: Well, today's your lucky day, because I—
Anais: Let me stop you right there. You know there are different types of intelligence?
Anais: I don't think you have any of them.
Gumball: I don't get it.
Gumball: Oh, come on!
[Anais slams the door]
Gumball: Oh, let me in! [Grunts] Don't be a club hog [Scoffs] Fine.
[Gumball walks to the door of the Fantasy Club room]
Gumball: Dad, can I join your fantasy club?
[Richard peeks from the door curtain]
Richard: [In Scottish accent] Who be there?
Gumball: It's me, Gumball.
Richard: Be you orc?
Richard: Be you dwarf?
Gumball: No, I'm your son.
Richard: Be you bearer of savory snacks for the elders?
Gumball: What? No.
Richard: Then begone! [Closes the curtain]
Darwin: What's up?
Gumball: Man, there's got to be a club for me somewhere.
Darwin: You could always join my club.
Gumball: What is it?
[Scene cuts to the school swimming pool, with Darwin swimming with other members of the club]
Darwin: Synchronized swimming!
Gumball: Hmmm. You're good, but I can do better. Here comes the swan dive of eternal beauty!
[Gumball jumps off the high dive and a swan appears behing him and honks, and he makes a big splash. It then starts raining in the swimming pool, but then stops]
[Scene cuts to Gumball's vision]
Gumball: [Coughs, sputters] So, how graceful was that?
Darwin: Dude, you can't swim.
Gumball: [Coughs] Fair point. Uh... has anyone seen my trunks?
[Scene cuts to the changing room]
Banana Joe: Touchdown!
Tobias: All right!
Banana Joe: Slam-dunk!
Banana Joe and Tobias: Yeeaaaahh!
Gumball: Uh, hey, guys. Is this the Football Club?
Banana Joe and Tobias: Yeeaaahh!
Gumball: Well, uh, did I miss the game?
Banana Joe: No, it's going on right out there.
Gumball: Why aren't you playing?
Banana Joe and Tobias: 'Cause we're the reserve team!
Gumball: Cool. So, can I join?
Tobias: I don't know. Are you man enough?
Gumball: [Scoffs] Me? I'm at least 50% man.
Tobias: Well, in that case, here's your towel.
Gumball: Thanks. So... do you guys ever get to play?
Tobias: Nah, we just hang out here and act kinda sporty.
Gumball: You guys just take showers, hang around in towels, and high-five each other?
Tobias: Heh! There's a little bit more to it than that.
Banana Joe: [Laughs and hits Gumball with his skin]
Gumball: Ah! Ow! Okay! Ow! Okay, okay!
[They all begin hitting each other and laughing, Hector comes in wearing his towel]
Tobias: Hey, Hector, is the game over?
Hector: Yeah. We lost. [Begins swinging his gigantic towel]
Banana Joe and Tobias: Oh.
[Hector hits them with his towel and they all scream. Gumball walks in pain as he attempts to enter the Tragedy Club room, but the door is quickly locked and the curtain is closed]
Gumball: Oh, why doesn't anyone want me in their club? It can't have anything to do with me -- my talent, my intelligence, or my general awesomeness. [Furious] You know what? Too bad for you jealous people, 'cause I'm starting my own club, and you are not invited!
Gumball's Club of Gumball
Gumball: Okay, I'd like to welcome everyone to "Gumball's Club of Gumball." First order of business: attendance. Hmm. Pretty good. Now, it seems like lately we've been let down by certain... family members. So I propose a little exercise in trust. Okay, don't worry, Gumball. Just close your eyes, let yourself fall back, and someone will catch you. [Puts off the glasses and runs on the other side of the room] Well, I'm a bit scared, Gumball. [Runs back and puts on the glasses] Well, that's why it's called a trust exercise. Come on, dude. [Puts off the glasses and runs forth] Mm... Okay. [Inhales, and falls backwards, naturally slamming against the floor. He groans in pain, then sighs] All in favor of disbanding the club say, "aye." [Raises hand] Aye. Motion carried.
[Scene cuts to Gumball wandering along the school corridor]
Gumball: Aw, man, I'm such a reject. I wish there was a club for people like me that no one liked. I'd join that club in a second. I wouldn't even care what it was about.
[The corridor lamps shut down, and a strange noise echoes through the corridor]
Gumball: Uh... what's going on?
Colin: Look no further, fellow loser.
Gumball: What the...?
Colin: We are the unsought, the weird.
Colin: Let me introduce you to...
Colin: ... The Reject Club! Always accepting new members.
Gumball: [Laughs] Thanks, I'm desperate, but not that desperate.
Colin: No, wait! We really need new members. We're so bored of talking to each other, we've been phoning up the talking clock for conversation. If you want, you could be our president or something. Or-or-or even better, our king! Picture this: Gumball Watterson, king of the rejects!
Felix, Bobert, and Ocho: Eh?
Gumball: [Laughs] What? King of the rejects? Seriously? [Laughs] Thanks for the offer, guys, but it's a "no." King of the rejects. [Walks away]
Felix: He rejected us.
Bobert: And laughed at our loneliness.
Colin: Well, we'll see if he's still too good for us when we've finished with him. To the nerd-mobile!
[The Reject Club walk like vampires, humming the old Batman theme]
[At the Wattersons']
Gumball: Rejected, even by my own family!
Nicole: Look, honey, you're not a baby anymore. You need to be able to do things on your own.
Richard: Oh, there must have been one club that wanted you.
Darwin: Yeah, The Rejects Club.
Gumball: But I politely declined.
[A brick flies through the window, onto the dining table]
Richard:[Screams] Oh, it's okay. It landed in the vegetables. [The brick falls onto the cake, squishing it] Aaaah! The cake!
Gumball: [Gasps] Look!
Darwin: [Points to the DVD on the brick] There's a DVD tied to it.
The Plan Unfolds
[Scene cuts to the living room]
Colin: [In DVD recording]Greetings, Gumball Watterson, from our secret lair.
Anais: Isn't that just the library?
Richard: Shh! There's more!
Colin: [In DVD recording]So, you think you're too good for us, eh? Well, you'll soon change your mind when we upload your embarrassing school record in a web video hosted by none other than you.[In DVD video recording, pretending to be Gumball]My name is Gumball Watterson and my IQ is smaller than my shoe size. I wore diapers until the age of eleven and once got detention for calling Miss Simian "mum."
Richard: [Screams] He looks just like you!
Colin: [In DVD recording]Our revenge plan is almost complete.
Computer: [In DVD recording]Uploading. Ten minutes until completion.
Colin: [In DVD recording][Evil laugh]And, cut! How was I? Evil enough?
Gumball: Oh, great, now the nerds are bullying me! I guess you want me to deal with this on my own.
Nicole: No. When someone picks a fight with one of us, they pick a fight with all of us. Everybody, get in the car. We've still got time to stop them.
Richard: But where is their secret hideout?
Anais: It's in the library!
Rush to the School
[The Wattersons rush to the school by car, then they run to the library door. Nicole tries to open it, but it's locked]
Gumball: Noooo! It's locked! My reputation is ruined!
Nicole: No, not yet. Quick! Someone make me angry.
Richard: Uhhh... I taped a wrestling match over our wedding video?
Nicole: Rrrrrrrrgggghhhh! [Pulls the door open and throws it] Go on without me! [Grunts as she kicks and pulls the locker doors open] Unh! I'm out of contro-o-o-o-l!
[Gumball, Darwin, Anais and Richard run along the library, when Felix, dressed as a wizard, appears in their way]
Felix: Thou shalt not pass!
Richard: You've crossed the wrong wizard, young man! I am level 40! Let the battle commence!
[Richard and Felix roll their dice]
Felix: Hurrah! I get the first shot. Meteor sword!
Richard: [Grunts in pain] Eugh! Ah! Ooh! Eh! He's good, but I can't afford to lose. Magic missile!
Felix: Doinggg! Deflected by the Shield of Rampor!
[Richard and Felix roll their dice again]
Richard and Felix: [Gasp] Freeze spell! [Become static]
Richard: Uh! You'll have to go on without me. I'm stuck for the next two turns.
[Gumball, Darwin and Anais pass by]
Gumball: Come on! The computer's just up ahead!
[A robot noise is heard]
Darwin: [Gasps] Watch out!
Gumball, Darwin, and Anais: [Gasp]
[The noise is getting louder]
Gumball, Darwin, and Anais: [Gasp]
[The noise turns out to be from Bobert]
Gumball: [Sighs] Relax. It's only Bobert. I can take him.
Bobert: Initiating combat mode. [Morphs into a giant robot]
Gumball, Darwin, and Anais: [Scream]
Anais: Don't worry, guys. I got this. [Begins sliding her feet on the floor]
Gumball: What are you doing?
Anais: Leave it to me. Just go around him.
Gumball: Are you sure you're gonna be okay? [Runs away with Darwin]
Anais: Don't worry. The power of physics has never failed me yet!
[Bobert slowly steps toward Anais, but Anais zaps him in the leg, causing him to fall unconscious]
Gumball: The computer! This is our chance to stop the upload.
Computer: Thirty seconds to completion.
[Colin appears, holding a ruler]
Darwin: [Gasps] There's a guard!
Colin: [Imitating lightsaber noises]
Darwin: That guy looks pretty dangerous.
Gumball: What are we gonna do?
Darwin: Leave it to me. Come on, punk.
Darwin: Let's dance. [Turns on the jukebox and begins dancing]
Colin: [Gasps] Such grace! The rhythm... must... synchronize!
Gumball: Thanks, buddy. [Looks at the computer]
Computer: Five seconds to completion.
Gumball: Yes! My reputation is safe.
Computer: Four seconds 'til completion.
[Ocho grabs Gumball's head, Gumball screams and attempts to grab the mouse]
Computer: Three seconds. Two seconds. One second 'til completion. Upload complete.
Computer: Sending to all school contacts.
Colin: [In computer video recording, pretending to be Gumball]My name is Gumball Trisha Watterson. That's right, Trisha is my middle name, and I was born without eyebrows and have to draw them on every day. On hot days I smell like pate and teachers are advised not to mention it. Also, I have a glandular problem that causes—
Gumball: Okay! Okay. You win. I'll join your club.
Colin: Are you kidding? Have you seen your school record? We're desperate, but we're not that desperate [Laughs and walks away with the Reject Club]
Gumball: [Sighs] Great. Rejected by The Reject Club!
In the Car
[Scene cuts to the highway]
Gumball: Well, that's my reputation ruined until college.
Anais: No, it isn't. I counter-hacked the main school server and rerouted the e-mail before it got to anyone.
Gumball: [Sighs] Oh, thank you, sis.
Darwin: Don't worry. We'll always be there for you.
Anais: You're part of the Watterson club... Trisha.
Gumball: Yeah, and whose great idea was that?
Richard: What's wrong with it? It's short for "Tristopher."
Nicole: Richard, I thought we agreed on "Christopher."
Richard: Christopher, Tristopher, same thing, right?
Darwin: So, what shall we do with these guys?
[The Reject Club members are shown to be tied up and their mouths are covered with handkerchiefs]
Nicole: Well, I think the responsible thing to do would be to drive them home and tell their parents what they've done.
[The Reject Club shakes their heads in disagreement]
Darwin: No? Then how about we spray you in honey and drop you off in the bear cage at the zoo?
[The Reject Club, again, disagrees to the idea]
Gumball: Okay, maybe you'd prefer to be dropped off naked at the mall?
[The Reject Club considers the idea, then nods their heads]
