The episode begins with Darwin and Sussie sitting next to each other on the school bus. As usual, Sussie is being annoying, this time by loudly commanding Darwin to look at every single thing she sees. Darwin is growing uncomfortable with this situation, but is too embarrassed to say anything to Sussie. He asks Gumball for help, but the cat simply mocks his brother for not having the guts to tell her to quit being so loud. Meanwhile, Darwin has had enough of Sussie's annoyance. Gumball, knowing what to do, simply—and politely—asks her to be quieter, and she happily obliges. Darwin is awestruck by this, and thanks his brother.
Later that day, Jamie cuts ahead of Darwin in the lunch line. Darwin attempts to protest, but none of the words actually come out. He starts to slap himself for "being a doormat." Gumball tells his brother that he can help him be more direct. Firstly, he tells Darwin to walk "like a dog with an itchy butt." Darwin actually does as he is told, and he thinks he understands the purpose of it, but Gumball admits he was messing with him and starts to laugh. Darwin gets mad and starts punching his brother for taking him "over the sandbox," so Gumball agrees that he will help him. Leslie is on the phone with someone, but the Watterson brothers cut him off. Darwin says he wants to be direct with Leslie, who is trying to sound smart, but is saying all of his words wrong, but when they get there, he starts "choking on his own frustration." With a little help from his brother, Darwin finally spits out his thoughts, which were highly offending, but Leslie seems to kindly take this to heart.
The scene goes to Gumball and Darwin using the computers in the library. Gumball forwards a picture of Tobias to Darwin, which he immediately gets upset about since Tobias uses the same pose in every picture of himself (the picture Gumball sent is just Tobias standing in random places and doing the same pose). When Darwin asks him what it means, Tobias says that it is "chunkin' the deuce." Darwin asks him again what that means, but Tobias does not answer; he just awkwardly scoots away from the library. Darwin expresses his happiness to Gumball. In the hall, Darwin starts to sing a song, to Gumball's dismay. Everyone joins in with Darwin, but he insults Jamie, Carrie, Masami, and Banana Joe in the process, causing the latter two to run away crying. Everyone gets angry at Darwin and leaves. Gumball then sees where Banana Joe ran off to cry to, which was in front of the lockers.
Gumball overhears Darwin yelling at Teri to stop spraying a doorknob. Teri explains that a doorknob has more germs than a toilet seat, but Darwin then sarcastically says people should open doors with their butts. Darwin tries to demonstrate, but Gumball comes in and asks what he is doing. Darwin says he is making a point, when he manages to get it open. However, Principal Brown is on the other side of the door. Teri complains to the principal that Darwin is being very unhygenic, to which Darwin panics, saying that Teri's hands are "covered in germs." Teri starts to panic and tries to see where they are, but Darwin licks Teri's hand. She runs off screaming while Principal Brown scolds him for acting this way, then assumes Gumball has something to do with it. Gumball denies this, but Principal Brown asks for clarification. Gumball admits he had a small role, which is all Principal Brown needs to hear. He sends them both to Mr. Small'soffice.
Mr. Small says he thinks expressing oneself is important, but does not like Darwin's comments about his ponytail. Darwin says he is trying his best, but then yells at him, saying he is tired of staring at "[Mr. Small's] hideous hairy man toes." Mr. Small puts his feet down and shows Darwin a drawing, asking him what he sees. Darwin interprets the drawing as "a very sad middle-aged man wearing sandals." Mr. Small is offended, and then smiles and says he has the solution to his problem: putting tape over Darwin's mouth.
Back in Miss Simian'sclassroom, Anton is annoyingly scratching himself, Sussie is breathing very loudly, Miss Simian is slurping her coffee, and Tina is tapping her nails on her desk. With every passing second, Darwin becomes more annoyed, and Gumball tells them all to get out before he hurts their feelings. However, Leslie tells him to stay and listen to Darwin, as he is "misunderstated," which is what finally sets the fish off. In a bout of rage, Darwin tells off everyone except Anton and Gumball. Shocked, his brother asks him if he can go back to being a nice guy. When Darwin does not reply, Gumball tries to see if he is okay. However, Darwin smacks his hand away and starts singing a villain-like musical number. He is cut off at the second half at the song by Gumball smacking him and telling his brother to meet him outside.
They then proceed to do a Street Fighter-like insult battle, and Darwin easily wins the first round by repeatedly telling Gumball he has a "big head." They continue to insult each other, while Tobias, Banana Joe, Bobert, and Anton stand by watching. However, Tobias says that the fight "is not as good as they thought" and the "spectators" leave. Gumball takes the "second round" when Darwin runs out of insults to use.
After winning the "second round," Gumball pauses the "game" and asks if Darwin has learned his lesson, but the fish continues to make shooting motions, which Gumball interprets as "cheating." Darwin quickly gains the higher ground over his brother, repeatedly telling Gumball he has a big head. However, Gumball becomes enraged and finishes Darwin off by telling him he is not his brother, and that all he is just a pet "who grew legs."
After he has won the "fight," Gumball finds Darwin crying on a pile of bricks. When his brother asks if he really meant it, Gumball starts crying and says no; all he wanted was to return his brother back to normal. Darwin and Gumball are both hurt, and the latter takes what he said earlier back. Darwin now understands what he was trying to do - if he hurt people's feelings, he will not do it anymore. Their friendship restored, the brothers hug. Darwin still insists Gumball has a big head, but his brother shrugs it off, saying that his head has hair on it.
The scene cuts to the bus, where Gumball and Darwin sits next to Sussie, who is being annoying again. Instead of talking it over, Gumball and Darwin use the emergency hammer to knock themselves out the window.
This episode may reveal what Darwin thinks of all the students.
The pixel-art sequence was created by Jérémie Périn and Mikael Robert.
This aired in the UK one day before the US.
Banana Joe's Season 1 design is seen on one of Tobias' photos.
Running Gag: Sussie repeating single words out of Darwin's sentences.
A flyer advertising Mr. Robinson's performance at the Elmore Senior Talent Show can be seen in the background in one scene. Its design is nearly identical to the one in "The Debt." In the same scene, an advertisement for Richard's former job is seen on the payphone.
Rocky's T-shirt has a different design in this episode, even though he had the same shirt as he did in Season 1 in "The Phone."
When Gumball was checking Tobias' pictures, the background on the computer is similar to Facebook.
The insult battle is a parody of Street Fighter II, with the VS screen resembling the style of Street Fighter IV.
An interesting note is that during the insult battle, the background music sounds strikingly similar to the theme music of the Street Fighter character Guile. This music can also be heard faintly during the beginning of the episode when Gumball is playing with his handheld.
Gumball's victory chant sounds similar to Chun-Li from Street Fighter, and Darwin's is similar to M. Bison.
やった (phonetic: yatta), the phrase Gumball used when he won a round, is a Japanese exclamation of accomplishment. It roughly translates to "I did it!"
Darwin's song "No More Mr. Nice Guy!" is sung in the style of a Disney villain's musical number, and is also a reference to the Alice Cooper song of the same name.
[The episode starts with Sussie and Darwin sitting next to each other in the school bus]
Sussie: [Sitting next to Darwin] Look, sun! Look, house! Look, roof! Look, ball! Look, door! Look, clown! Look, bird! You're not looking! [Points to a dog] BIRD! BIRD! BIRD! BIRD! BIRD! BIRD! BIRD! BIRD!
Darwin: That's a d—... [Sighs]
Sussie: [Smacks Darwin with arm] WAIT! [Cut to traffic light] RED! RED! RED! RED! RED! RED! RED! [cut to Sussie] GREEN! [Laughs softly]
Darwin: [Moans; squeezes through the side of the seat, Gumball is playing Street Fighter on a device looking similar to the Game Boy Advance and Anton is sleeping beside him] Dude, I need you to grab the emergency hammer.
Gumball: I'm not breaking the window.
Darwin: No, I need you to knock me out.
Gumball: How about you just ask Sussie to calm down a little?
Darwin: [Moans again] I can't...
Gumball: What the.. [Pauses video game] You're embarrassed, aren't you?
Darwin Just use the hammer...
Gumball: [Laughs] Darwin Watterson, the fish who grew legs at the expense of his guts!
Darwin: Shut up!
Sussie: HEY, DARWIN! [Darwin squeezes his head back out] Which noise do you prefer? ALALALALALALALALALALALALA! or AKAKAKAKAKAKAKAKAKAKAKAKAKAKA!
Gumball: [Sticks head on top of Sussie and Darwin's seat] Excuse me, Sussie, but can you be a little quieter, please?
Sussie: Certainly, young Gumball, I'd be more than happy to oblige!
Gumball: Thank you.
Darwin: [Motions taking hat off]
Gumball: What's that?
Darwin: That was me, taking my hat off to you.
Sussie: [Whispers]: Hats!
Darwin: I still don't understand how you can be so direct with people?
Gumball: OH! It's really hard, you have to think the words and then move your lips at the same time so it makes the right sound.
Darwin: [Grabs Gumball's face and whispers] Teach me...
[Jamie cuts in line. Darwin stares at her]
Jamie: Yeah, that's what I thought.
Darwin: [Mouths argument] That whole argument I just won only went on in my head, didn't it?
Gumball: Well... nothing happened in reality, so I'm gonna have to say yes.
[Darwin starts hitting his face]
Gumball: What's that about?
Darwin: That's me beating myself for being such a door mat.
[The bell rings]
Gumball: If you want me to teach you how to be direct, I can. But you have to promise to do exactly what I say. No questions asked!
Darwin: [Kneels, starry-eyed] I promise.
Gumball: I want you to walk like a dog with an itchy butt.
Darwin: [still starry-eyed] I shouldn't have promised.
[Gumball is walking past Tobias and Idaho in the schoolyard, while Darwin drags his butt on the ground like a dog.]
Gumball: [Waves to Tobias and Idaho] Hi, guys.
Darwin: I think I actually understand the purpose of this exercise. You're ridding me of my inhibitions by destroying the little dignity I had.
Gumball: No dude... [laughing] I was just messing with you!
Darwin: WHAT?! [Starts punching Gumball] WAS IT REALLY [Punch] NECESSARY [Punch] TO TAKE ME [Punch] OVER [Punch] THE SAND BOX?!
Gumball: [Happy sigh] Just tell me who you want to be direct with, and I'll show you how it's done.
[Scene jumps to Leslie on the payphone]
Leslie : [Talking on the phone] Calm down, honey, you're being over grammatic, this guy is too shellfish and he's being a total control Greek. [Gumball pushes the switch to end the phone call] Do you mind? I was in the middle of a condensation!
Gumball: Wow, I see what you mean now... Come on, tell him how annoying he is!
Darwin: [Phew] Okay. [Phew] You know, Leslie? When you try to sound intelligent sometimes, you just- [Darwin starts choking] You just-
Gumball: Come on man, speak your mind! You're so bottled up you're choking on your own frustration! [grabs and starts squeezing Darwin] SAY [Squeeze] WHAT [Squeeze] YOU [Squeeze] THINK!
Darwin: [With a loud voice] WHEN YOU TRY TO SOUND SMART AND MIX UP YOUR WORDS YOU SOUND LIKE A FOOOOOOOOOOOOOL!
[Everyone is stunned for a moment]
Leslie: I- I don't know what to say... Thank you! Thank you for telling me, I'll be forever graceful for your honesty!
Gumball: It's- it's grateful...
Leslie: Ah, yes, I'll be forever grapefruit for your honesty.
[Leslie walks away, as Gumball bows to a delighted Darwin]
Gumball: HAHA! Hehe.
Gumball: Tobias just posted a photo, I'll send it over. [Sends photo]
Darwin: Oh, for goodness sake! This is another thing that bugs me. [Skims through a series of Tobias's photos] He's always pulling that stupid pose! So annoying...
Gumball: Well it's not really that annoying, it's just a photo, buddy...
Darwin: It's not though is it? It's ALL the time! [Looks at Tobias doing his pose] Dude, FYI, you look totally lame when you pull that pose, WHAT DOES IT EVEN MEAN?!
Tobias : It's chunkin' the deuce, man.
Darwin: And what does THAT mean?
[Tobias slowly walks/scoots away]
Darwin: [Looks at Gumball suprisingly as he gasps happily]
Darwin: I don't understand, for my whole walking life I had to keep my mouth shut, having to deal with everyone annoying little habits, but now I can say what I like... [Darwin begins to sing] I feel like...
Gumball: Dude, what are you doing?
Darwin: I feel like...
Gumball[Facepalms and sighs]
What He Thinks About Us!
Darwin: Ever since I was a young fish, I always held my tongue, Never spoke the words I felt inside and now my time has come. I'd push my feelings deep deep down, now I'll tell the world,[Jumps on top of a ladder, knocking Rocky off of it]exactly what I think and feel, about every boy and girl.[Ocho, Masami, Banana Joe, Anton, Jamie, Alan, Idaho, Bobert, Tobias, Tina, Carrie, and William appear to sing along]
Rest of Class: Every boy and girl!
Rest of Class: [The students (joined by Carmen) follow Darwin down another hallway]Gonna tell us what he thinks about us![Miss Simian does a backwards cartwheel and walks backwards in front of the students]Gonna tell us what to do! Gonna tell us what he thinks about us! Gonna show us something new!
Darwin: Stop! Masami's popular and funny, but your friends just like you for your money.[Masami frowns, turns grey, and floats away, crying]
Rest of class: We only like you for your money!
Darwin: Jamie's rude and impolite because she's half cow half troglodyte.[Jamie walks away with her head down]
Rest of class: She's half-cow half-troglodyte!
Darwin: Carrie thinks her style's unique, but she's just one more emo freak.[Carrie becomes shocked by Darwin's insult. Shot cuts to Banana Joe]
Rest of class: She's just one more emo freak!
Darwin: Joe, your jokes are lame and lazy, and you sing just like a dog with rabies!
[Banana Joe runs away, crying. The rest of the students walk away, ending the song. Darwin continues to have his hands raised proudly]
Gumball: Hmm, where do people go when they run away crying like that?
[Gumball follows Banana Joe, and sees him sitting on the floor next to the lockers]
Banana Joe: [Sees Gumball] Uh, haha, I feel a bit silly now.
Darwin:[Offscreen] OH JUST STOP IT! Alright?!
[Shot cuts to Teri spraying a door handle]
Teri: Well, what does it matter to you? You do know there are more germs on an average door handle than there are on a toilet seat.
Darwin: Well, if that's the case, we should all open doors with our butts! [Tries to open door with his butt] Almost got it.
Gumball: Darwin, what are you doing?
Darwin: Just proving a point...
[Darwin opens the door, revealing Principal Brown]
Darwin: TA DA!
Teri: Principal Brown! Darwin is being recklessly unhygienic!... [She moves into the sunlight to show her "ulcers"] And it's giving me ulcers, See?!
Darwin: OH, MY GOSH! Your hand, its covered in germs!
Nigel Brown: Darwin Watterson! This is not like you at all! I can only assume that Gumball has something to do with it.
Gumball: I've got nothing to do with it at all!
Nigel Brown: Nothing?...
Gumball: Well maybe I kinda set him off.
Nigel Brown: That's all I needed to know! Both of you, to the school counselor, immediately.
A Nice Dose of "Shut Up"
Mister Small : As much as I think it's important for you to be able to express yourselves freely, I don't think comments about my ponytail are appropriate. The back of my head does not look like a horse's buttocks!
Darwin: I swear I'm trying my best Mr. Small, but I just can't stop myself from saying- I'M TIRED OF STARING AT YOUR HIDEOUS! HAIRY! MAN TOES!
Mister Small : Eh, uhum. Interesting, I wanna try something, what do you see when I show you this ink blot?
Darwin: A very sad middle aged man wearing sandals.
Mister Small : [Thinks Darwin is referring to him, and takes a big breath] I think I have the right treatment for your problem.
[Gumball and Darwin walk out of his office; Darwin has tape on his mouth]
Gumball: I'm impressed on how you're managing all this buddy. I thought for sur-
[Darwin is freaking out]
Gumball: EVERYONE GET OUT OF HERE! HE'S GONNA HURT YOUR FEELINGS REAL BAD!
Leslie : No! We need to listen to him, He's just misunderstated.
[Darwin, enraged, stands up and tears the tape off his mouth]
Darwin: Hey, chin bag, how about you learn to breath through your nostrils. Oh I'm sorry... YOU DON'T HAVE ANY!
Sussie: [Whispers] Nostrils.
Darwin: And how about you clip those stupid nails, they're not gonna make you look more feminine. In case you haven't noticed, [Talks through his teeth] you're a ten ton sack of reptile flesh!
Sussie: [Whispers] Reptile flesh.
Darwin: And as for you! [Points at Miss Simian] The only thing worse than hearing you slurp your coffee is watching it stick to your rancid lady mustache!
Sussie: [Whispers] Mustache.
[Miss Simian runs away crying]
Gumball: Uh, dude, I know I told you to be direct and all but you're acting like a full blown atomic jerk right now, can you uhh, just go back to being a nice guy?... Dude?
[Darwin slaps Gumball's hand]
Darwin: No more Mr. Nice Guy, I found a new style, with claws and pointy teeth and a villainous smile! Goodbye, Goody Two-Shoes! I'm no longer uptight, cause now I'm a shark and I'm ready to bite! And I'll say what I want, and the truth's gonna sting! I'll be brutal and blunt, it will hurt when I sing! AHAHAHAHAHHA! So look out worl-
[Gumball slaps Darwin]
Gumball: You and me, outside, now.
Street Fighter in the Schoolyard
Gumball: I don't want to do this man, but it's the only way! You need to learn that words can hurt.
Announcer: Round One! Fight!
Darwin: Your head is so big that you have to put your shirt on feet first! [Shoots an energy ball at Gumball] Big head! Big head! Big head! Big head!
Gumball: Ow! Stop It!
Darwin: [Shoots an energy ball] Big head!
Gumball: That's cheating!
Darwin: [Shoots an energy ball] Big head!
Gumball: You keep using the same move!
Darwin: [Shoots an energy ball] Big head!
[Gumball echoes and collapses]
Announcer: Darwin wins! Perfect! Round Two! Fight!
Gumball: You're so ugly that when you entered an ugly contest the judges said no professionals! [Shoots an energy ball]
Darwin: You're so dumb you put stamps on your e-mails! [Shoots an energy ball]
Gumball: You're so short that your head smells like feet! [Shoots an energy ball]
Darwin: Your brain's so small that your thoughts have an echo! [Shoots an energy ball]
Gumball: Your cheeks are so big that people don't know which end of you they're looking at! [Shoots an energy ball]
[Camera cuts to reality, Gumball and Darwin are still pretending to be in the game]
Gumball: Pshoo! Cling! Pew!
Gumball: Your face is so greasy that people put on weight when they look at you! [Shoots an energy ball]
Tobias : Nyeh, it's not as good as I thought it'd be.
[Tobias, Banana Joe, Anton and Bobert leave, still making cheering motions, camera cuts back to the game]
Gumball: You're so bald, that when you take a shower you get brainwashed!
Darwin: You're so... [Panics] I got nothing!
[Gumball shoots an energy ball and Darwin is "stunned," Gumball comes close with an energy ball in his hand]
Gumball: You're so chubby the back of your head looks like a pack of wieners.
[Gumball punches Darwin with energy, Darwin flies into the air and then back down, smashing a dumpster. Gumball celebrates]
Announcer: Final Round!
Gumball: Wait a minute, pause.
[Gumball holds out his hand and the "game" pauses]
Gumball: Darwin, I think this has gone far enough. Surely you understand what I'm trying to say to you. It's good to speak your mind sometimes but.. wha- what, what are you doing?
[Darwin is making shooting motions]
Gumball: Hey, you unpaused! That's cheating!
Darwin: Big head! [Darwin starts shooting energy balls] Big head! Big head! Big head!
Gumball: [Energy starts emanating from Gumball] Okay, I didn't want to do this, but you leave me no choice. You are not my brother. [Gumball starts to use a combo move] You are just a pet who grew legs!
Darwin: [Flies into the air] Ahh!
Announcer: Ultimate combo!
Gumball: I'm sorry, you forced me to do this.
[Darwin starts sobbing. Gumball realizes what he has done and rushes over as the scene returns to reality.]
Darwin: Did you really mean that?
Gumball: [Crying as well] No! [hugs him] I just wanted you back to normal, it just came out!
Darwin: It really hurt!
Gumball: It really hurt me too! I never thought it before, you're totally my brother!
Darwin: [Regains composure] Well, I think you've made your point, and if that's how I made other people feel, I don't want to do it anymore.
Gumball: [Happily sighs] It's good to have you back, buddy. [They hug]
Darwin: You still have a big head, though.
Gumball: Well, at least mine's got hair on it.
[On the school bus, Sussie is seated beside Gumball and Darwin]
[Gumball and Darwin stare at each other and nod. Darwin gives the emergency hammer to Gumball. The camera cuts to outside the bus. Gumball and Darwin fly out the window, where the camera freezes. Episode ends]
