The episode begins with Richard telling Gumball the story about a watch, one of the Watterson's heirlooms. He explains that the watch was fought over by the Wattersons and the Finklehimers, explaining his father's victory at a yodeling contest and him giving it to Richard when he was still a young boy. Then he finally ends his discussion with Gumball by giving him the watch, following family tradition.
In the next scene, Gumball is on the bus with Darwin. He shows the watch to his brother, and says that it is useless since it cannot tell time at all (the watch actually having roman numerals which Gumball does not know how to read). Darwin reveals that he was also offered the watch before Gumball received it. He tells Gumball that he declined to have it since it was "busted up cowboy junk." Gumball then asks Darwin to hold the watch and pretends to tie his shoelaces. When Darwin realizes that he had been tricked by his brother (as Gumball does not wear shoes), Gumball tells him that "he who holds it, owns it." Darwin is forced to keep the watch.
While walking in the school hallway, Gumball is suddenly rushed on by Darwin who offers a deal. The deal is that he will keep the watch if Richard gives them a better gift, and if he gets to keep that gift. To this, Gumball agrees and both of them shake hands. Then Darwin asks Gumball to check his hands, hinting that he had tricked him while they were shaking hands. But then Gumball shows empty hands, and tells Darwin to check his hands instead. The latter becomes frustrated when he sees that the watch is still with him, and even more frustrated when Gumball disappears from sight. Then he sees his brother at the end of a hallway, doing "magic fingers" before disappearing from view.
In their bedroom, Darwin tells Gumball that he gave the watch to an old man. This makes Gumball worried, and says to Darwin that he should not have given the watch to "some random guy." Darwin replies that he only did so because he thought that Gumball was trying to get rid of it, and this worries Gumball all the more when he is confronted with telling Richard about the watch. They hug and start arguing about who should tell Richard about what happened with the watch. Suddenly, Richard appears with them, hugging them and quietly asking them what they are talking about. Gumball lies and tells him that he was talking to Darwin about how much they liked the watch. In response, Richard tells them that he loves them.
Gumball and Darwin go to Marvin's front yard, and beg for the watch. However, Marvin insists that the watch belongs to his family, the Finklehimers. At this, Gumball quietly asks Darwin about why he gave it to a finklehimer of all people. Marvin explains that it is polemic justice. As one last attempt, Gumball asks how Marvin can turn down a crying child, then tries to cry hard when Marvin points out that he is not crying. In the end, Gumball's eyes pop out, and Marvin tells them to get off his lawn.
At the school lunchroom, Gumball and Darwin have lunch. Darwin expresses his guilt over losing the watch, but Gumball tells them that they should just forget about it and ignore their emotions. But after Gumball's stomach rejects a pea, he admits that it is because he has a knot in his stomach caused by the guilt, and says that they must get the watch back.
Back at Marvin's front yard again, Marvin tells them he does not want to trade anything for the watch. Gumball offers eternal youth (while Darwin echoes this to try and get Marvin interested). Marvin becomes interested in the offer until Gumball admits that he does not have it. Darwin suggests getting him a girlfriend, and Marvin agrees to this. But not before Gumball makes him look younger.
At the restaurant Dump's Cave, Hexagon Lady and Marvin go on a date. She asks him how long he has "been so surprised" (due to Gumball making him look young and surprised at the same time, with paper clips stretching his saggy skin). When Marvin tries his best to reply, he accidentally pulls off some paper clips and nervously smiles. Hexagon Lady asks for the check after this.
At Marvin's front yard again, Darwin tells Marvin that it was not their fault that they were not compatible. Marvin blames them for the "back alley face-lift" that they used on him, to which Darwin says that it was either that or a bag over his head. Gumball apologizes, and tells Marvin that he is too old for a girlfriend. Marvin tells them to go away again, but instead Gumball grabs his cane. Gumball threatens an initially frightened Marvin that he is going to beat himself up, and accuse Marvin of doing the deed. Marvin responds that Gumball must be "lilly liver" to do such a thing. Not knowing what "lilly liver" means, Gumball attempts to beat himself with the cane. This only makes him delusional, and he starts speaking gibberish. He rejects Darwin's offer to walk him home, saying that he is capable of doing so himself before leaving the scene. Darwin sighs, saying he does not have the heart to tell Gumball that he is going the wrong way.
At home, Gumball and Darwin try hiding from Richard until Gumball cannot take it anymore and says that they have to tell Richard the truth. When Darwin gets mad at Gumball, he unintentionally gives him an idea. Together, they go to Marvin's house dressed as the grim reaper, but accidentally cause Marvin to faint. While attempting to give him CPR they find that he is still breathing, and they also find the watch under his hat. Before they can get it, he wakes up. After Gumball gives a small emotional speech to Marvin, the latter just mocks them.
Back at home, Gumball and Darwin try to gently tell their dad about the watch. But Richard realizes that the way they are acting tells him that they have something terrible to confess. So the brothers just confess, and at first Richard does not understand and cries as well. At learning that they gave the watch away, Richard stops crying and shows apathy for the family heirloom, much to his son's surprise.
The brothers return to Marvin's home, and inform him that they are allowing him to keep the watch. But before they can finish, Marvin now allows them to have it back. After arguing with tricks, they come on an agreement: Marvin keeps the watch, but the watch would still belong to the Wattersons.
Back in their house, Gumball, Darwin, and Richard watch TV. While watching, the show reveals that the very same watch that they were handling all the time is actually worth 700 dollars, and two were only ever made. At the same time, Marvin also watches the same show, and grins sinisterly with the watch. Both Marvin, and the Wattersons get out of their houses. Marvin hops on to his electric scooter, and Richard, Gumball, and Darwin "borrow" the other scooters from the other senior citizens.
Marvin and the Watterons have a (really slow) chase, with Richard on one scooter, and the two boys on the other. Richard uses Mr. Fitzgerald as a ride to get to Marvin's scooter, but is repelled by Marvin. Later, he tries to jump on Marvin, but falls too early and smashes in from of the senior citizen. Then Gumball and Darwin's scooter comes down a flight of stairs, and heads straight for Marvin's scooter. While swerving sharply to avoid collision, the watch falls down, and the scooters stop and face each other. They both "charge" at each other, full speed. But having a change of mind, they abandon their scooters, choosing their lives over 700 dollars.
The scooters both hit each other slowly with a harmless "tong," and Richard (bracing himself) calms down. Just as Darwin suggests that they should just split the money, the episode ends with a freeze frame of both scooters exploding with the watch.
When Gumball and Darwin ride the scooter down some stairs, they scream with their mouths closed.
In the scenes where Gumball, Darwin and the Senior Citizens are on Marvin's front lawn, Marvin's house is green, but in the scenes where Gumball, Darwin and Marvin are at Marvin's front door, Marvin's house is white.
When Marvin pushes Richard off his scooter, Richard's foot can be seen, but when Darwin and Gumball's scooter hits Marvin's scooter, Richard disappears.
When the camera zooms in on Darwin when he pops out of the box, Daisy Flakes is misspelled as "Dizzy" Flakes. In the same scene, Darwin is missing one eyelash on his right eye.
[Richard, holding an old watch, is telling Gumball a story]
Richard: This watch has been at the center of a feud between the Watterson and Finklehimer families for centuries. It was found by your great-great-great-great-grandfather Bucktooth Watterson, who lost it to an evil man called One-Legged Finklehimer in a jig contest. However, Bucktooth's son, your great-great-great-grandfather... [Skips] ...but then Elivine Finklehimer took it, even through he had never slapped a peacock in his entire life! [Time passes] ...believe me or not, all that time, the watch was hidden inside Louie Finklehimer's girdle... [Even more time passes] ...then, when my dad finally retrieved the watch after a good old yodeling contest, he gave it to me. And now, little man, I give the watch to you. [Hands the watch to Gumball]
[On the school bus, Gumball has the watch in his hand]
Gumball: Aww, I hate it! This watch is wonder weak, it doesn't even tell the time. What the derp is V past X supposed to mean?
Darwin: Wait, did you get that from Dad?
Gumball: How'd you know?
Darwin: He offered it to me first. He told me this really long boring story full of people I didn't care about, and I said "No! I don't want no busted up cowboy junk."
Gumball: [Hands the watch to Darwin] Do you mind holding this for a second? I need to tie my shoelace.
Darwin: Sure. [Realizes something] Wait, you don't have any shoes.
[Gumball appears on top of the seat behind Darwin]
Gumball: He who holds it, owns it.
[Gumball slowly goes down]
The Watch Switches Hands
[Gumball is walking down the school corridor, Darwin runs to him]
Darwin: Okay, okay! I'll keep it. But on one condition, if at any point Dad offers us a better present, I get dibs. Deal?
[They shake hands]
Darwin: [Smugly] Now check your hands.
Gumball: What? This one, [Reveals his hand is empty] or this one? [His other hand is also empty] Now check yours.
[Darwin is suddenly holding the watch in his fin]
[Gumball has disappeared]
Darwin: DOUBLE WHAT!?
[Gumball appears in the left corner while moving his arms around his face, like a magician, then leaves]
[At the Wattersons' house, Darwin tells Gumball what he did with the watch]
Darwin: I gave it to an old man.
Darwin: I said, [Yells] "I gave it to old man!"
Gumball: Shh! I heard it the first time, it's just that you DON'T GIVE AWAY A FAMILY HEIRLOOM TO SOME RANDOM GUY!
Darwin: But I thought you were trying to get rid of it.
Gumball: [Sighs] What's Dad gonna say now?
Darwin: [Gasps] Is he gonna cry? 'Cause if he's gonna cry, I'll cry.
Gumball: Oh, don't cry bubble cheeks, it's my fault as well.
[Gumball and Darwin hug and then talk quietly]
Darwin: So, since it's obviously your fault, you're gonna get it back right?
Gumball: Well, I would if you hadn't been an total slack-jawed goober and gave it to him.
Darwin: But none of this would have happened if you hadn't been such an ungrateful jerk in the first place.
Gumball: You do it.
Darwin: No, you do it.
Gumball: No, you do it.
Richard: [whispering] What are you guys talking about?
[We see Richard hugging Gumball and Darwin]
Gumball: Uh, how much we like the watch?
Richard: [Still whispering] I love you guys.
The Watterson-Finklehimer Feud Continues
[At the seniors' house, Gumball and Darwin are crying on the ground for the watch]
Marvin: I'd be more than happy to give this watch back, if it belonged to you! But my name is Marvin Finklehimer, and this watch belongs to the Finklehimer family.
[Gumball whispers to Darwin]
Gumball: Dude, did you really have to give it to a Finklehimer?
Marvin: Ha! Call that poetic justice.
Gumball: Can you really turn down a helpless crying child?
Marvin: You're not crying.
[Gumball tries to cry]
Darwin: Dude, are you trying to cry, or lay an egg?
[Gumball struggles to cry, holding his hand up, then his eyes explode]
Marvin: Get off my lawn.
[At the school cafeteria, the recess bell rings]
Darwin: What are we gonna do?
Gumball: Well, we just have to agree to never speak about that watch again.
Darwin: But I feel so guilty...
Gumball: Then we shall deal with our emotions like grown-ups: push them down deep inside ourselves and ignore them for the rest of our lives.
[Gumball swallows a pea, but the pea comes out of his stomach and back up his throat, causing him to spit it out and hit Darwin]
Darwin: Oof! Hey! What was that?
[Gumball starts crying]
Gumball: It's the guilt, I have a massive knot in my stomach and my body just won't let me eat, we have to get that watch back somehow!
Marvin: For the last time, there's nothing in this world that I'd want to trade for this watch!
Gumball: Hmmm. [Walks to foreground] What about the one thing that man has desired since the dawn of time? What about the one thing a man at the dusk of his life craves for more than anything else? What about the secret that has eluded every scientist, alchemist and adventurer of this world? What about-
[Gumball moves very close to Marvin]
Gumball: Eternal youth?
Darwin: [Echoes] Youth..youth..youth..youth.
Marvin: I'm listening.
Gumball: Don't have it.
Darwin: But how about a girlfriend?
Gumball: We might need to make you look a little younger.
[At the restaurant Dump's Cave, Marvin is on a dinner date with the Hexagon Lady]
Hexagon Lady: So Marvin, how long have you been so surprised?
[Marvin is revealed to have lots of binder clips holding up all his wrinkles, supposedly to make him appear younger]
Marvin: Ahhhhh... [The clips on the left side of his face drops off, revealing sagging facial features. He smiles nervously]
Hexagon Lady: [To waiter] Check please.
Darwin: It's not our fault you weren't compatible!
Marvin: It is your fault for giving me that back alley facelift!
Darwin: It was either that or a bag over your head, her advert said no one over 25!
Gumball: I'm sorry dude, but you kinda look like a microwaved toad.
Marvin: [Waves his cane] Get out of here, I'm keeping the watch!
[Gumball grabs Marvin's cane and hefts it in his hands]
Gumball: I wish it didn't have to come to this, Marvin.
Marvin: [Whimpers] What you are doing?
Gumball: [Holds up the cane] I'm gonna beat myself senseless, call the cops and accuse you of doing it!
Marvin: [Calms down, and scoffs] Huh, I think you're a bit too lily-livered for that, son.
Gumball: I don't know what that means, but I'm gonna prove it wrong. [Knocks himself in the head with the cane]
[Gumball knocks himself in the head once, then his eyes fail to focus. He becomes delusional and starts talking with difficulty; it is evident that the blow dealt him brain damage]
Gumball: [Slurring] Ok, I can't remember why I'm angry at you, so I'm gonna go.
Betty: Is he talking to me now?
Gumball: [Gives back the cane] No dude, I'm talking to you. [Points at Marvin]
Darwin: Ok, I'm gonna walk you home now.
Gumball: I can walk home by myself, I'm perfectly capable of putting one foot in front of the other foot... [Goes right and leaves the scene while babbling]
Darwin: [Sighs] I don't have the heart to tell him that he's going the wrong way.
[In the Wattersons' kitchen, nothing happens in the scene for a while, until Gumball pops out from the sink]
Gumball: [Gasps for air] I can't hide like this anymore, we're just gonna have to tell Dad the truth.
[Darwin pops out of a Super Golden Flakes cereal box]
Darwin: Oh sure, great plan. So how do you want to do it? You can start by rejecting his love, while I sucker punch him with the lack of respect that we have for his entire family heritage or, if you prefer, I'll just rip out his heart while you TEAR HIS SOUL IN HALF!
Gumball: Get out of your box, you just gave me an idea.
[Someone with a scythe rings the doorbell to Marvin's house. Marvin opens the door, and is shocked]
Grim Reaper: [Ominous voice] I'VE COME FOR YOU, MARVIN.
Marvin: [Gasps, then faints]
[Gumball and Darwin get out of the Grim Reaper costume]
Gumball: What have we done!?!
Darwin: You said he'd just bargain for his life with the watch, but instead he's gone the way of the dodo!
Gumball: Just give him CPR.
[Darwin pushes Gumball out of the way and futilely attempts to perform CPR by blowing air into Marvin's mouth]
Gumball: What the? Do it properly, man!
Darwin: I'm not touching his mouth, it looks like the end of an elephant's trunk.
Gumball: Ok, hold on. [Gumball runs into the house while Darwin continues to do his "CPR"]
Gumball: [Comes out of the house] Move aside. [Darwin moves aside while Gumball puts tissue paper around Marvin's mouth] Come on Marvin, don't go into the light.
[Gumball prepares to perform CPR on Marvin but Darwin stops him]
Darwin: No wait!
[One of the sheets of tissue paper is moving, which shows Marvin is still breathing]
Darwin: Ahh, he's been breathing all this time.
Gumball: Shhhhh. [Points at the watch in Marvin's hat]
[Gumball slowly reaches for the watch but Marvin suddenly wakes up]
Marvin: I'M KEEPING THE WATCH!
Gumball and Darwin: AHHHHHHH! [Gumball runs to Darwin's side]
Marvin: It belongs to my family, NOT YOURS!
Gumball: [Sighs] Look sir, I shouldn't have given that watch to Darwin and he shouldn't have given it to you, so now I'm begging you- [Camera changes to Marvin's face as he becomes less angry] 'Cause all I care about is that my dad gave it to me, it'll break his heart when I tell him I lost it.
Marvin: [appears to soften up, but suddenly mocks Gumball] Me me me me me me.
[Richard is playing video games, the camera then shows Gumball and Darwin with puppy eyes]
Darwin: Hey Mr. Dad, you look great, have you lost weight?
Richard: Hmmm, let me check. [Richard's moves his head and counts the folds of fat under his chin] One, two, three, four five six. No, same as always. Wait a minute, what have you done wrong?
Gumball: [Surprised] What? What gave it away?
Richard: That's what I always ask your mother before I confess something terrible.
Gumball: [Starts crying] I was just messin', but Darwin... and I gave the watch to him...
Darwin: [Starts crying too] And then I gave it to Marvin, and then we tried to get it back, but he wouldn't give it back!
Richard: [Crying as well] What... are you... talking about?
Gumball: The watch!
Richard: [Stops crying and plays video game] What? That weird Roman compass thing? No one cares about that.
[Gumball and Darwin stop crying]
Richard: Yeah, I just wanted to get rid of it. I even tried to give it to Anais before giving it to Darwin. Just tell Marvin he can keep it.
[Gumball rings the doorbell and Marvin comes out]
Gumball: Hey Marvin, listen I just-
Marvin: [Puts his hand out] Let me stop you there. I've been thinking, I only wanted this watch because my father wanted it all his life, and by keeping it, I'm sentencing you to the same punishment, so please take it. [Puts his hand out with the watch]
Gumball: Let me stop you there. [Grabs Marvin's hands] We just found out that our dad doesn't care, so you can keep it. [Pushes Marvin's hand back]
Marvin: No, I want you to have it. [Gives Gumball the watch]
Gumball: [Reveals an empty hand] Check your hands, you keep it.
Marvin: [Reveals an empty hand as well] Hmmmm, check behind your ear, you keep it.
Gumball: [Gumball checks behind his ears and reveals an empty hand yet again] Now check inside your pants.
Marvin: But I don't wear any- [Marvin is suddenly wearing pants] Ha ha ha, OK kid, how 'bout this? I'll keep it for now but it's still yours. You can get it back anytime you like, deal?
[Scene changes to the Wattersons' TV which is showing an auction channel]
Dealer: This table is worth about a thousand dollars.
Customer: Oh my.
Dealer: However, this coffee stain brings the value down to about ten dollars.
[Camera changes to show Gumball, Darwin and Richard laughing and then changes back to the TV]
Dealer: Now this pocket watch is a very special piece. Only two were ever made and I'd say it's worth approximately 700 dollars.
[The customer and the Wattersons gasp and the scene switches to Marvin who is watching the same show in his living room and he grins evilly]
The Feud Ends
[Both the Wattersons and Marvin get out of their houses, then Marvin gets on his electric scooter and tries to escape. The Wattersons run after him but stop as Richard kneels to the ground]
Richard: Noooo, we're never gonna get him!
Darwin: I don't know, we could probably catch up with him if we jog.
Richard: Noooo, we're never gonna get him!
Darwin: Wait, I've got an idea! [Asks Donald] Can we borrow your scooter sir?
Donald: Sure, but you're going to have to fight me for it. [Tries to get out of his chair, but after several failed attempts he sits back down, extremely fatigued] Just take it.
[The Wattersons chase Marvin on electric scooters, Darwin and Gumball on one and Richard on another]
Gumball: We'll never catch him!
[Richard turns around and sees Patrick jogging toward them]
Richard: Don't worry, I have an idea!
[Richard jumps onto Patrick's back]
Patrick: What the- Hey! What do you think you're doing- [Richard twists Patrick's antlers and he speeds up like a motorcycle] Woahhhhhhhh!
[Richard catches up with Marvin and he jumps onto his scooter]
Richard: A-ha! Gimme back the watch you prune-faced pincher.
Marvin: Get your sausage fingers out of my face. [Bites Richard's arm]
Richard: AHH HA HA, it's all gummy and lukewarm! Gah! [falls off]
[Marvin laughs. but is rammed by Gumball and Darwin]
Gumball: You said we could have it back anytime we want.
Marvin: Oh, you can have it right now.
Marvin: For 700 dollars! [Kicks Gumball and Darwin's scooter away]
Gumball and Darwin: Ahhhhhhhh! [As they slowly hit the glass carried by Construction Men]
Gumball: What are you doing carrying glass through a park?!
Hank: What are you doing ramming into an octogenarian on a battery-powered wheelchair?
Gumball: Yeah, fair point. [Scooter reverses]
[Scene changes to Marvin riding in his scooter]
Marvin: 700 dollars! I can finally afford to pay off my credit card bills! Or maybe I'll buy those gold dentures I've seen in hip hop videos!
Richard: I'll tell you what you need to buy! BANDAGES! [Jumps from the roof of the restroom. He is too early, so he faceplants into the ground] Owwww.
Marvin: I'll mail 'em to ya. Ahahahaha! [Drives around Richard]
Gumball: This isn't over, Marvin!
[The scene changes to Gumball and Darwin's scooter which is coming down a flight of stairs. In order to avoid collision, both scooters swerve sharply]
Gumball and Darwin: Ahhhhh.
Marvin: [Drops the watch] Ahhhh, the watch!
[Both scooters end up facing each other, with the watch right in between]
Marvin: Forget it Watterson, the watch is mine and therefore the money is mine!
Gumball: It was never yours and it will never be, Marvin Finklehimer!
[Both scooters move towards each other]
Gumball: AHHHHHHH! [Talks to Darwin] Are we actually gonna risk our lives for 700 dollars?
Darwin: Let's bail. [Gumball and Darwin jump off the scooter]
Marvin: Yeah, fair point. [Marvin gets off too]
[Richard runs into the scene]
Richard: [As the scooters are about to hit each other] Get out of the way, it's gonna explode!
[The scooters hit each other with a harmless "tong." Richard calms down]
Darwin: Hey, that's great, now we can sell the watch and split the money.
[The episode ends with a freeze frame of both scooters exploding, presumably destroying the watch]
