The episode begins with an orange fire hydrant and a blue mailbox up close. The next scene shifts to Gumball and Darwin wearing winter coats because they are hiding from their next door neighbor, Gary. After recalling several embarrassing situations where they did not know his name (an awkward greeting, trying to save Gary from an oncoming train, and jumping out the school window when Principal Brown brings him to their class), Darwin realizes that Gary is standing right behind them, and the two boys immediately run away, but Gary explains that he has a package for them.
Back at home, Darwin and Gumball are panting, where Darwin says that they ask him what his name is, but Gumball reminds him of the window of opportunity and tells him that after the third time you try to ask someone’s name, that window gets a lock on it, and a dirty, aged Richard explains to the boys that he has been avoiding Gary too. Gumball decides to receive the package from Gary anyway, but Gumball still does not know his name, confusing Gary, who leaves the package with the other unopened packages.
That night, Gumball and Darwin go through Gary's mail in an attempt to find his name written on a letter. However, all of them have no trace of his name, and the situation worsens when Darwin shreds the letters and puts the remains back into the mailbox, calling it the "perfect crime."
Later at the mall, Gumball and Darwin, disguised as charity workers, try to convince Gary to sign a petition. Confused, Gary asks why, and Gumball explains that the Mayor of Elmore is going to knock the library down to build a hospital, then he will knock down the hospital, and build an orphanage, then finally build an luxury apartment. Gary caves in and signs the petition, but suddenly runs away, claiming they need direct action now. As Gumball and Darwin walk away, the mayor, who has been listening in on the conversation, calls his associates and puts this exact plan into action.
At the park, Gary is feeding the pigeons when Gumball pushes Alison into him, and he and Darwin attempt to wed the two, but Gary freaks out and runs away. After that, Gumball and Darwin pose as mailmen to get Gary to sign their delivery form. Gary ends up crying, believing he has been replaced as the neighborhood mailman. He signs, but his writing is unreadable due to the form getting wet from his tears.
Gumball and Darwin begin putting up posters around town asking if anyone knows Gary's name. Two Russian agents drive up next to them, and tell them Gary's real name. The boys then find Gary at the mall, and address him by his real name: Harry Gedges. Gary asks them who told them his name, and Darwin tells him it was the Russian agents, who drive up at that moment.
Gary runs away, and Gumball and Darwin follow him. As they evade the agents, Gary explains that the name "Gary Hedges" was a pseudonym given to him by the witness protection program after he testified in court against some bad people twenty years ago. The three return to Gary's house, only to find the Russian agents have tracked them there, due to Gumball writing Gary's exact address on the posters, as well as showing how to get into his house. Gary decides he is going to have to skip town, but Gumball comes up with another idea.
As the Russian agents approach Gary's house, Gumball, Darwin, and Gary stick a dummy in Gary's likeness out the top window. Gary throws it onto a power line, and the Russian agents watch as the dummy is run over by several different vehicles. They then believe Gary is dead, and drive away. Gary is relieved that the plan worked, but Gumball tries to explain that that was not how the plan was supposed to go. Before he can finish, Gary's house explodes as per Gumball's original plan. As Gary stares at the burning remains of his home, Gumball asks if he and Darwin should call him Harry Gedges or Gary Hedges. Gary responds he would rather the two never talk to him again, and the episode ends.
The scene where Gumball, Darwin, and Gary try to escape the Russian doberman agents is a reference to The Grand Budapest Hotel, when Zero Moustafa and M. Gustave escape prison and head to a mountaintop monastery.
In the scene where the Russian agents find Gary, he says, "They found me. I don't know how, but they found me!" This line is identical to a line from Back to the Future.
[The train passes by, crushing both Gary and the beans. Some of the beans splatter on Gumball and Darwin]
Darwin: We'd better call him the paramedics.
Gumball: Why? I´m pretty sure the paramedics is not his name.
Darwin: No, I mean call a doctor.
Gumball: I don't wanna be awkward when they ask us what he's called.
[In another flashback, Gumball and Darwin are in class while Principal Brown speaks to them]
Nigel Brown: And here to talk about his job is the town's mailman, mister-
[Gumball and Darwin gasp and jump out the window]
Darwin: [Beaten] Maybe we should have waited. Principal Brown was about to tell us his name.
Gumball: [Beaten] Yep, I panicked.
[Cut back to present time. Gary is standing behind Gumball and Darwin with a package in his hands]
Gumball: Yeah, remember this time? This was really awkward.
Darwin: [Whispers] This isn't a flashback.
[Gumball looks behind him and notices Gary. Both he and Darwin run away]
Gary: Wait up, I got a package for ya!
[Gumball and Darwin run inside their house and slam the door shut. Both of them catch their breath for a moment]
Darwin: We can't avoid it any longer. We're going to have to ask him his name.
Gumball: Are you insane? You're forgetting about the window.
Darwin: Uh-uh. I am not jumping through any more windows. I'm still finding bits of window frame in my gills from the last time.
Gumball: No, I'm talking about the brief window of opportunity where it's socially acceptable to ask someone what their name is. After the third time you've met someone, that window closes. And every time you see them after that, the window gets another lock on it, another bolt, another shutter. At this point, our window with that guy would be harder to open than a ski store in the Sahara.
[Gary rings the doorbell]
Gary: What about your package?
Gumball: [Looks through peephole to see Gary] What's he trying to deliver, anyway?
Richard: It's probably for me. [Richard is shown on the couch looking very fatigued, growing white hair and extremely long fingernails, and with several jars on the floor around him] I don't know that guy's name, either. I've just been avoiding him by not leaving the house and getting everything delivered.
Darwin: But isn't he the mailman?
Richard: I didn't think it through.
Gumball: And what's with the jars? You don't need to leave the house to go to the bathroom.
Richard: Didn't think that through, either.
Gumball: Right, we need to find out his name without him realizing. [Opens the door]
Gary: Hey, Gumball.
Gumball: Hello, misterrr...
Gumball: [In his mind while prolonging saying "mister"] Okay, Gumball, just keep going until you see a look of recognition on his face.
Darwin: [laughs, pushes Gumball to the side as he continues saying names] I'm so sorry about my friend, Mister, uh...man...
Gary: I guess I'll just leave it with the others.
[Gary sets the package down amidst several other boxes. He slowly backs away as Gumball and Darwin continue incomprehensibly saying names]
The "Perfect" Crime
[At night, Gumball and Darwin walk next door to Gary's mailbox]
Darwin: Isn't it illegal to go through someone's mail?
Gumball: What's worse, being locked in a prison, or being locked in a prison of social awkwardness? [Opens Gary's mailbox and sticks his hand inside] Jackpot!
Darwin: Isn't it weird that a mailman leaves mail in his own mailbox?
Gumball: I guess some people don't like to take their work home with them. [Starts reading the letters] To the occupant, to whom it may concern, to the resident, to the homeowner, to the bill payer, for your attention, sir, madam, sir, to the birthday boy? Ah, come on! [Notices Darwin is pushing all the letters into a paper shredder] What are you doing?
Darwin: Destroying the evidence.
Gumball: But we could've just put it back in the mailbox!
Darwin: Good idea. [Takes the shredded letters and places them all back inside the mailbox, then flips the flag on the mailbox up] The perfect crime.
[Gumball looks at Darwin disapprovingly]
Sign Here, Please
[At the mall, Gumball and Darwin are both waiting for Gary to walk by. Gumball is wearing very tall, messy hair, and Darwin is wearing a Jamaican hat and a small goatee. Soon enough, Gary walks by]
Gumball: Excuse me, would you like to sign our petition?
Gary: Uh, I'm sorry, [As he walks past, Darwin falls over] I don't have time to- [Trips over Darwin]
Gumball: Thank you for stopping, please sign here. [Shoves clipboard into Gary's face]
Gary: [Gets up] Um, I don't really-
Darwin: Hey, if you can just write your name, please. Full name, nice and clear, black capitals, big as you can.
Gary: What's it for?
Gumball: Uh, the mayor is gonna knock down the library to build a...
Darwin: A hospital.
Gary: Oh. That doesn't sound so bad.
Gumball: Yeah, but then he's gonna knock down the hospital to build a...
Darwin: An orphanage!
Gary: Again, not so bad.
Gumball: But then he's gonna knock down the orphanage and build a...luxury apartments! Luxury apartments.
Gary: That's terrible! Give me that! [Snatches clipboard from Gumball and prepares to write his name, but then stops] No, wait, we need direct action, and we need it now! [Runs off with the clipboard]
[Gumball growls and pulls the fake hair off. Darwin does the same, revealing a large afro under his hat. As they walk away, the mayor is seen reading a newspaper. He then lowers it and calls someone]
Mayor of Elmore: It's the mayor here. I've got an idea. We're gonna knock down the library and build a hospital. No, no, that's just step one.
[At the park, Gary is feeding the pigeons. Alison passes by]
Alison: [Mumbles to greet him]
[As soon as Alison walks offscreen, Gumball pushes her onto the bench next to Gary]
Gary: What the-
[Darwin brings in a radio and begins playing an arrangement of the "Romeo and Juliet Overture." Gumball and Darwin make Gary and Alison face each other. Gumball runs off while Darwin makes both of them rest their hands on each other, and then he runs off. Gumball comes back with a dinner table decorated with candles, and then runs off again. Darwin returns with a plate of spaghetti and sticks the ends of a noodle in Alison and Gary's mouths. The music changes to an Italian-themed cue, and Gumball comes back briefly playing an accordion. He tosses it away, and he and Darwin both push Gary and Alison's heads closer together. The boys run off again, with Gumball pulling away the tablecloth, plates, and candle. Darwin returns with a cup and a bottle of soda. Gumball comes back with a wedding ring and drops it into the cup. Darwin fills the cup with soda, then empties it on Alison's hand. As he does this, Gumball moves Alison's hand underneath the cup, and the ring ends up on her finger. The boys run offscreen with the table and park bench as Alison blushes at Gary. Darwin briefly runs behind Gary and kicks the back of his knee, causing him to kneel. Gumball comes back and positions Gary's hand on Alison's, then nods Alison's head. Darwin places a top hat on Gary's head, while Gumball places a bridal veil on Alison. Darwin positions Gary to stand up, and changes the music to the wedding march. Gumball returns to act as the minister]
Gumball: Okay, wedding vows! Go!
Alison: Uh, I hereby state that I, Alison Sandra Gator, do take you as my lawful wedded husband.
Gumball: Okay, your turn! Go!
Gary: Uh... I hereby state that I...
Gumball: [Makes a high pitched squeal]YES!!
Gary: I think this is all happening too fast! [Throws top hat to the ground, runs away]
Gumball: [Throws book to the ground] Gosh darn it! [He and Darwin angrily walk away]
Alison: People say you're meant to mourn a relationship for half the amount of time you were together. [Stares at her watch for a few seconds] I'm done.
Mail for the Mailman
[Gumball and Darwin, both dressed as mailmen, approach Gary's front door. They both give each other smug looks. As Gumball sticks a newspaper through Gary's mail slot, Darwin picks up a garden gnome on his porch. Gumball wraps it in newspaper, gives it to Darwin, and rings Gary's doorbell]
Gumball: Package delivery. [Gary opens the door] Sign here.
Gary: What? But I'm the mailman for this neighborhood. Why didn't anybody tell me I'd been replaced? [Starts crying. His tears run down his face and onto the clipboard] Decades of experience: worthless. Thrown in the scrap heap like garbage.
Gumball: Yeah, if you could just, uh-
Gary: How am I gonna find another job at my age?
Gumball: [Moves Gary's hand to the clipboard] You could just... sign here.
[Gary signs whilst crying. Gumball takes the clipboard, gives him the wrapped gnome, and then backs away with Darwin]
Darwin: Did we get it?
[The clipboard is shown, but all of the writing is smudged due to Gary's tears]
Gumball: Nope, nothing makes handwriting harder to read than an old man's tears.
[Gary, still crying, unwraps the gnome]
Gary: And I already got one of these! [Goes inside, still crying]
[Gumball is seen putting up a poster of Gary, with text reading "Do you know this man?"]
Darwin: There must be something we haven't tried.
Gumball: I've been braining so hard my think hurts. [Shakes his head]
Darwin: Wait, I know! If we had amnesia, we could tell him we forgot his name and it wouldn't be embarrassing.
Gumball: Great! How do you get amnesia?
Darwin: We hit each other on the head.
Gumball: Wait, how are we gonna remember that we tried this?
Darwin: Write it on your arm.
[Gumball pulls back his shirt sleeve, revealing he has written amnesia on it three times, with the first two being crossed out]
Gumball: Hm, that explains the headache.
[A black car then rolls up next to Gumball and Darwin. Someone inside it speaks to them in a gruff Russian accent]
Russian Agent: Hey, you two. That guy on your poster.
Gumball: You know his name?
Russian Agent: Let's just say he's an "old friend."
[Meanwhile, Gary is seen at the mall collecting mail from its mailbox. Gumball and Darwin suddenly rush up behind him with large smiles. Gary screams]
Gumball and Darwin: [Through gritted teeth] Hello. Harry Gedges.
Gary: Who told you that was my name?
Gumball: Pfft, we've always known it. [Chuckles] Obviously.
Gary: [Yells] Who told you that name?
Darwin: Uhh, those guys? [Points to the Russian Agents' car as it rolls up]
Gary: [Gasps] They found me. I don't know how, but they found me.
[The Russian Agents' car window rolls down, and their sunglasses then do in the same way. Gumball and Darwin then notice Gary running away]
Evading the Agents
[As Gary is running through the mall, Gumball and Darwin run up alongside him]
Gumball: Wait, what's wrong with calling you "Harry Gedges," Harry Gedges?
[Gary runs into an opening elevator]
Gary: Because that's my real name!
Gumball: Yeah, we know it is, Harry Gedges.
[As the elevator closes, Leonard Daniels is thrown out]
Leonard Daniels: Ooh. I don't mind.
[Gary presses all the elevator buttons, then hits the emergency stop button. He then climbs out the top of the elevator while Darwin speaks]
Darwin: Like we're always saying, "good morning Harry Gedges," "how are you doing Harry Gedges," "happy birthday Harry Gedges."
Gary: Stop saying it!
Darwin: Why, Harry Gedges?
[Gumball, Darwin, and Gary climb up the elevator shaft]
Gary: That's not the name I've been using.
Gumball: What do you mean, Harry Gedges?
[Gary runs out of the mall's roof exit, with Gumball and Darwin close behind]
Gary: I've been living under a pseudonym for the last twenty years!
Darwin: Looks more like a fedora, Harry Gedges.
[The three jump from the mall's roof to another building]
Gary: Not my hat! A pseudonym is a fake name! [He, Gumball, and Darwin are seen clinging onto the bottom of a moving truck] It was given to me by the witness protection people when they moved me to Elmore for my own safety.
Gumball: Why, Harry Gedges?
[The three are then seen riding a gondola in the mountains]
Gary: I testified in court against some very bad people. And ever since then, I've had to live under the fake name that you know me by.
[Gumball and Darwin stare at Gary for a few moments]
Gumball: Which is mister...B- [Darwin slaps Gumball]
Darwin: No! We don't know your name, alright? tell us what it is.
Gary: Wait, you don't know my name? We've been neighbors since you were born. If my life wasn't in immediate danger I'd be really hurt right now. [Sighs] It's Gary Hedges.
[Gumball and Darwin both look at him with realistic dog snouts on their faces]
Gary: I'm outta here.
[He, Gumball, and Darwin cross to the gondola next to their current one]
Gumball: So let me get this straight. Real name is Harry Gedges, and your fake name is Gary Hedges? [The three then end up in the sewers outside Gary's house] That's not very imaginative.
Gary: [Lifts up hubcap] I didn't choose it! [They all enter Gary's house] Okay, there's no way those guys could have followed us.
Darwin: [Pulls back curtain] Who, those guys?
[The Russian Agents slowly pull up near Gary's house. One of them reads the poster Gumball put up earlier. He continually unfolds it, with each new fold containing more info on where Gary lives]
Russian Agent: "Do you know this man? He lives at ten twenty-four York Street. Here's a map. This is the house. If the front door is locked there is a key under the gnome."
Gary: How on earth did they find out where I live?
Gumball and Darwin: [Awkwardly] Uh, lucky guess?
Gary: [Sighs] Then I got no choice. I'm gonna have to skip town and leave behind my new life and beautiful home.
Gumball: [Slides his finger along an extremely dusty table] I think beautiful's overselling it.
Darwin: Dude, not the time!
Gumball: [Cleans his finger on the back of Gary's shirt] Yeah, sorry. Ah! I got it. You don't have to skip town if they think you're [Slides his thumb past his neck and makes a squishing sound]
Darwin: I don't think pretending he's a duck is gonna help.
Gumball: No, they'll leave if they think he's already kicked the bucket. I know exactly what to do.
The "Death" of Gary
[The Russian Agents exit their car. One of them growls. Inside the house, Gary is nervously packing his clothes and a passport into a suitcase. Behind him, Gumball and Darwin put a dummy resembling Gary in the window]
[Gary begins handling the dummy, and the Russian Agents hear his voice]
Gary: Oh no, I was just cleaning the windows and now I have lost my balance! I hope there is no tragic consequence!
[Gary throws the dummy onto a power line, causing it to get electrocuted. The dummy falls to street. As the Russian Agents prepare to draw their weapons, a car drives by running over the dummy. The agents continue to draw their weapons, but then a semi carrying empty cars drives by, running over the dummy even more. The agents retract their weapons, but at that moment, the empty cars on the semi's trailer come loose. The cars roll backward, running over the dummy again. The agents draw their weapons again, but the empty cars reach an incline and roll back downhill, once again running over the dummy. The agents stare at the motionless dummy before shrugging, returning to their car, and driving off. As they drive away, the run over the dummy. Once they are out of sight, Gary emerges from the bushes]
Gary: Ha! It worked! Throwing that dummy out of the window was a great idea! Now I get to keep my life and my beautiful home!
Gumball: Yeah, it wasn't supposed to fall out of the window. It was meant to look like you were in the house when it-
[Gary's house suddenly explodes. Gary stares at the fiery mess, shocked and disheartened]
Gumball: This might not be the best time to ask, but, would you rather we call you Harry Gedges or Gary Hedges?
