[Richard, Darwin and Gumball are having breakfast]
Gumball: Hey dad, can you pass the sugar?
Richard: [Giggles] Sure, Gumball. [Gives him the vessel] Here's the sugar. [laughs softly]
[Gumball pours the sugar onto his cereal, eats a lump, and then vomits it on Darwin]
Darwin: It probably just needs more sugar. [Pours more]
[Richard laughs softly]
[Gumball tries it again, but vomits it on Darwin again but much longer than before. Darwin then blocks the vomit with newspaper, which the vomit breaks through, and then a spoon, before Gumball stops vomiting]
Gumball: It tastes terrible.
Darwin: [Tastes it] It tastes like salt.
Richard: [Laughs loudly] That's because I swapped the sugar for the salt! [Laugh softly] It was the greatest prank, ever.
Gumball: Okay, you got me. But that's not the greatest prank, this is. [Handles a ketchup bottle and points to Richard] Hey, dad. Does this ketchup look funny to you?
Richard: Hmm... I'll check. But afterwards, don't forget to show me that prank you were talking about. [Checks the ketchup bottle] Looks okay to me... [Gumball sprays the ketchup to his face] AARG!
Gumball and Darwin: [Laughs]
Richard: What did you do that for? You got ketchup all over me.
Gumball: That was the prank.
Darwin: Yeah, we did it because it's funny.
Richard: [feels sad] No, it isn't. It's only funny when it happens to someone else! How could you do this to your own father?! [Run away from Gumball and Darwin, crying]
Nicole: [Appears from the kitchen] That wasn't very nice. You two should know better.
Gumball: What?! You didn't tell him off for pranking us.
Nicole: You know it's too late for your father. I want you two to apologize by the time I get back. [Leaves the house]
Darwin: Do you think Mr. Dad will be okay?
Gumball: Nah, he probably forgot about it already.
[Gumball and Darwin are now playing their game. Soon, Richard came by]
Richard: [Puts his hands as he hiding something] Hello, children.
Gumball and Darwin: Hey, dad!
Richard: Why don't you try on this lovely new shoes? [Attempts to prank them]
Gumball: [Feeling suspicious on Richard] This is a prank, isn't it?
Richard: [Nervously] What, prank? What? Me prank you? What? Nooo, Ha, ha, ha. No, huh, no. Hmph. Sheesh.
[Richard at the shoe store with both shoes in his hands]
Richard: I would like to return these shoes, please.
Larry: Unfortunately, sir, you seem to have filed them with baked beans.
Richard: [Angrily] I did nothing of the sort, sir.
Larry: Well, I'm sure you wouldn't mind putting them on and taking a walk to prove it, huh?
Richard: And I'm sure I wouldn't mind either. [Puts the shoes on, steps on the baked beans and shivers] On second thought, I think I shall keep them. I happen to have grow quite attached to them. [Walks away with a squishy sound coming from his feet]
[Richard is at the couch with a tape player and headphones on his head, presses the play button]
Recording: Welcome to "Pranks for beginners". Over the next 30 minutes...
Richard: [pauses the tape] 30 Minutes? That's 2 subs, a muffin, and a tub of ice cream. Oh! And I better get a sausage for the last 19 seconds.[leaves the room]
[Gumball and Darwin change the tape]
Richard: [comes back to the room] Mental note: next time take food for the journey back as well. [puts the headphones back on and presses play]
Gumballon tape: Step 1: Go out onto the roof of the house.
[Richard is on top of the roof while Gumball and Darwin are hiding behind the car]
Gumballon tape: Step 2: Take off all of your clothes.
[Gumball and Darwin snicker, Richard has only his underwear on]
Gumballon tape: Step 3: Pretend that you're are a ballerina while repeatedly slapping yourself in the face.
[Gumball and Darwin are still snickering]
Darwin: Dude, this cannot be real.
Richard: [on his toes and slapping himself] I'm a ballerina, I'm a ballerina, I'm a ballerina, I'm a ballerina.
Gumballon tape: Step 5: Realize you've just been pranked [Richard frowns] Step 6: Try and fit down the chimney, head first.[Richard smiles]
[Gumball and Darwin are still snickering while Richard is struggling to get down through the chimney. The day then turns night, with Richard still stuck in the chimney]
The Next Prank
[Scene cuts to Richard on the table snoring, with prank drafts all around him on the table and the floor]
Gumball: Aww look, he's been up all night trying to find a way to get back at us.
Darwin: [Slaps Richard] Yup, he is definitely out cold.
[Gumball and Darwin grins in mischief]
[Scene changes to Gumball and Darwin pushing Richard out into a river on an inflatable lifeboat]
Gumball: I can't wait to see the look on his face when he wakes up.
[Gumball and Darwin laughs as Richards floats away]
Gumball: [stops laughing] Dude, I don't think he's waking up.
Darwin: Where does this river go?
Gumball: Ahh...I think it goes out to sea?
[Scene changes to Richard on the lifeboat floating on the sea]
Darwin: Do you think he will be mad Gumball?
Gumball: Nah, it's just a small... harmless... prank.
[Scene zooms out, showing Richard on the lifeboat floating further into the sea]
Back at Home
[Gumball and Darwin is watching TV together]
Gumball: [Door opens] Dad! Are you okay? Can I get you something to eat or something?
Richard: No, I still have plenty of coconuts. [shows a bag of coconuts]
Darwin: What happened to your clothes?
Richard: I ate them. [Turns around, and walks up the stairs back to his room]
Darwin: How do we know when we have taken this too far?
Gumball: I think we'll know when we get there.
Richard's Door Prank
[Gumball and Darwin are scribbling on a magazine with crayons, then the camera zooms out, showing Richard placing a bucket full of water on top of the kitchen door]
[Gumball and Darwin notices Richard's prank]
Gumball: This is just too easy.
[Scene changes to Kitchen]
Richard: [gasps, then puts out his newspaper]
Gumball: Hey, Darwin and I are thinking of going outside.
Richard: Oh, okay.
Gumball: Shall we going to the front yard or the backyard?
Richard: [Giggles] The Backyard, it's always nice at this time of the year. [Continues to giggle]
Gumball: [faces to Darwin] Hey... Do you know what else would be fun?
Gumball: Going through... The window.
Richard: [folds the newspaper quickly as he thinks his prank will be useless] What are you talking about? Are you crazy?
Gumball: Well, how else are we gonna get to the backyard?
Richard: Through the door!
Gumball: The what?
Richard: The DOOR! Like this. [His pranks backfires. The bucket falls onto him] WAAAH!!! [He runs out of the kitchen shouting, crashing into things]
[Scene changes to the ambulance siren]
Paramedic: Sir, please stop struggling so we can get the bucket off.
Richard: It's dark!
Paramedic: How did this happen?
Gumball: Well, we saw our dad putting the bucket on top of the kitchen door and...
Richard: You saw me?! How can you do this to me. You betrayed me, my own children! I look like a fool! [Starts running all over the place]. I don't want anyone to see me like this!
Paramedic Eddie: Sir, please calm down.
Richard: [Shouting] Leave me alone! Get off my lawn!
Paramedic: It's no use. Eddie, tranquilizer.
Paramedic Eddie: [Blows a tranquilizer on Richard's butt]
Richard: Leave... me... alone... [Yawns and falls asleep, allowing the bucket to be removed from his head]
I'm Gonna Prank You
[Scene changes back into the Wattersons' house. Richard's pops his head back in shape]
Gumball: Hey dad! So... things got a little carried away there. What with you know, you going out to sea, and... getting tranquilized and.. everything... So it was a lot of fun but I think it's about time to call it a day. Okay?
[Richard didn't respond]
Darwin: Yeah, I think we all learnt a valuable lesson about not taking pranks too far. Let's have a feel-good hug.
[Gumball and Darwin hugs Richard, but Richard still does not respond]
Darwin: This doesn't feel like a happy ending.
[Richard cuts Gumball and Darwin out from the family photo]
Darwin: [Whispers to Gumball] What are we gonna do?
Gumball: [Whispers to Darwin] I don't know. [Thinks for a few seconds, then sees a bucket on top of the door] Huh? Maybe we should just go outside again, this time through the front door.
Darwin: Good idea Gumball!
Gumball: Okay, prepare to get wet. [Opens door, but the bucket containing dried cement falls in front of Gumball and Darwin almost hitting them] WHAT THE WHAT!?
Richard: [Turns around, looking insane] I'M GONNA PRANK YOU! [Jumps out of sofa, making "scary" crazy faces]
[Gumball and Darwin screams in fear, runs up the stairs into the bathroom and shuts the door, while Richard bangs on the door]
Darwin: [Notices Gumball panicking] Gumball! What's wrong with you? You're hyperventilating! Stop panicking Gumball, just calm down. Get [slaps] a [slaps] grip [slaps], snap [slaps] out [slaps] of [slaps] it! [slaps]
Gumball: CUT IT OUT! You're making it worse!
Darwin: Oh, sorry. There there buddy [Strokes Gumball], there there. Is that better?
Gumball: Much better. Now hold me and tell me that everything is going to be okay.
Darwin: [holds Gumball] Everything is gonna be okay buddy.
Gumball: How about a little kiss?
[Darwin kisses Gumball]
Gumball: [Relieved] haa.
Richard: [Crashes into the bathroom] PRANK TIME!!!
[Gumball and Darwin screams, and run out of the bathroom and down the stairs, hiding under the sofa. Gumball hyperventilates again]
Richard: [Breaks through the ceiling] Where are you?
Darwin: We're not under the sofa.
Richard: Ha Ha! [Flips the sofa up, only to find Gumball and Darwin gone] Huh? [Looks at the TV] Hmm...
Gumball: [Realizes that Richard has spotted them] And that's it for Tonight's News @ 5. Here's Garwin with the weather.
Darwin: It would be very hot here with temperatures soaring to 20°C, below zero on the Northern front of the warm drift on the isolating regions of the cold snaps, and there will be a beautiful rainbow.
Richard: Hmm. Wonder what else on TV? [Uses the remote to change the channel]
Gumball: [As an actor] How could you?
Darwin: [As an actor] It's not what it looks like.
Gumball: [As an actor] Please, don't leave me.
Gumball: [As an actor] Nooo! It can never be the same again!
[Richard changes channel again]
Darwin: [As an documentarian] And here, captured in film for the first time, we see the Chicken Crab.
Gumball: [Acts as a Chicken crab]
[Richard changes channel one more time]
Gumball: [Sings] A music video, a music video!
Darwin: [Sings] Yeah, we are in a music video!
Gumball: [Sings] This is what you call a music video!
Darwin: [Sings] Oh baby, we're singing, I am in a [Richard holds up an unplugged TV cord] music videooooo...
[Gumball and Darwin runs around the house shouting, with Richard chasing them]
Gumball: Look! The air vent, it's the only way [Squeezes into the vent]. It's no use. [Holds up Tomato Ketchup bottle as Richard charges towards them] Stand back! I'm warning you. You leave me no choice! [squeezes bottle, but the ketchup splats onto Gumball and Darwin's faces instead] Ahh..
Richard: [Laughs]. You should see your faces, you really thought I was going to catch you. [Laughs]
Darwin: What? You mean that the whole thing was a prank?
Richard: Ya. And you totally bought it. [Laughs]
Gumball: Dad! That was terrible. How can you do that to your own children?
Richard: It's always funny when the jokes are on someone else. [Laughs]
Darwin: You almost dropped the block of solid concrete on our head!
Richard: Yeah. I have no idea what happened with that. It was wet when I poured it in.
Gumball: And the bursting through walls and stuff?
Richard: I'll be honest with ya', I broke 5 ribs, but it was all worth it, just to see your faces.
Gumball: Good job dad, you totally got us, we're sorry we pranked you.
Richard: Wahaha, no, it's me that should be sorry.
Darwin: But it was us who took it too far.
Richard: Yeah, but I was the one who started it.
[Nicole and Anais comes back and are shocked by the destruction the boys made]
Nicole WHO DID THIS?
[Episode ends, with Gumball, Darwin and Richard pointing to each other and saying "IT WAS HIM!"]
Gumball, Darwin, and Richard are sitting at the dining table. Gumball and Darwin are eating cereal for breakfast, while Richard is reading the newspaper. Gumball asks Richard to pass the sugar, but Richard giggles and passes him the salt instead. Gumball sprinkles the "sugar" onto his cereal, thinking it's sugar. After having a spoonful, he spits it out at Darwin. Darwin, also thinking it's sugar, sprinkled more salt onto Gumball's cereal suggesting that it needs more sugar. Gumball takes another spoonful of the cereal and promptly spits it at Darwin again. When he finishes, Darwin tastes some of the vomit and finds out it was salt that they sprinkled onto the cereal, causing Richard to burst out laughing at the prank he pulled. Richard claming that it was the best prank ever, Gumball decides to get back at his dad by tricking him into looking closely into a ketchup bottle. As he looks into the bottle, Gumball squeezes the bottle making ketchup getting all over Richard. Gumball and Darwin start laughing, but Richard can't take a prank and runs off crying. Nicole scolds the boys. Gumball complains about how she didn't tell Richard off for pulling a prank, but Nicole says they know it too late for their father and tells them to apologize before she returns home.
Later in the day, Gumball and Darwin play a video game when Richard comes back, asking them to try on some new shoes. The boys accuse him of trying to pull another prank. Richard, panicking, and realizing that his prank has been seen through, denies their claim. The scene then cuts to Richard at a shoe store, trying to return the prank shoes. Larry denies his request, saying that he filled them with baked beans. In an attempt to prove there were no beans in the shoes, Richard puts them on, pranking himself because he was the one who put the baked beans in there. Knowing he wasn't going to get a refund, Richard walks off, saying he wants to keep the shoes because he feels "grown quite attached to them".
Back at the house, Richard begins listening to a How-To-Prank tape on a portable cassette player. The tape tells him the lesson will take thirty minutes, so Richard decides to eat thirty minutes worth of food, which consists of two subs, a muffin, a tub of ice cream, and a sausage for the last nineteen seconds. While Richard goes to the kitchen to eat, Gumball switches the How-To-Prank tape with a tape he recorded himself to prank Richard. Not knowing that Gumball switched the tapes, Richard follows the instructions.
The 6 steps are as follows:
1. Go outside onto the roof of the house. 2. Take off all of your clothes (only his underwear is shown). 3. Pretend that you are a ballerina while repeatedly slapping yourself on the face. (skipped, yelled "I'm a ballerina!" repeatedly). 4 (5). Realize that you've just been pranked. 5 (6). Try and fit down the chimney, head first.
Gumball and Darwin laugh at him the whole time. After step 5, Richard gets stuck in the chimney for hours.
The next day, Gumball and Darwin find Richard asleep in the living room, surrounded by papers with schemes on how to prank them. Gumball and Darwin realize that this is a perfect opportunity for another prank. They put their sleeping dad onto a rubber raft and push him down the river, sending him out to sea. The 2 of them realize that he won't wake up until he's lost on an island in the middle of the ocean. When he finally back home he's sunburnt, has no clothes on, and carrying a bag of coconuts. Upon being asked about what happened to his clothes, he responds that he ate them. He then walks up the stairs with his bottom showing. Gumball and Darwin start wondering whether they're taking this prank thing too far.
Later, Gumball and Darwin start vandalizing people's faces in a magazine while Richard places a bucket over a door in another attempt to prank the boys. Gumball and Darwin see and hear him, Gumball stating "This is too easy". They decide to tease their dad, saying they should go to the backyard through the window instead of the door. Richard gets angry saying the idea Gumball brought up is crazy. Desperately wanting them to get soaked with water from his prank, in his frustration, he demonstrates how to open the door, causing the bucket to fall on him and get stuck on his head. The situation is so serious that the paramedics have to come to pull it off. Gumball reveals that they seen him attempting the prank, but Richard realizes that he's been tricked and accuses Gumball and Darwin of betraying him. This drives him into a panic of insanity and Richard starts running across the yards, wailing and panicking about his failure at pranking Gumball and Darwin. One of the paramedics tells Richard to calm down, but Richard won't listen to him, shouting them to "LEAVE ME ALONE! GET OFF MY LAWN!", so he had to be tranquilized by Eddie, one of the paramedics. As he lays asleep, the paramedics easily pull the bucket off.
Gumball, Darwin, and Richard sit together in the living room. Richard has an angry look on his face while Gumball and Darwin look guilty. They try to end the prank war, but Richard still looks angry, and worse yet, he cuts out Gumball and Darwin from the family photo because he thinks that they are the reason for his failed pranking attempts. Gumball and Darwin see another bucket on top of the front door and figured they would purposely fall for this prank to make their dad feel better. When they open the door, they expected to get hit with water, but instead, a heavy block of cement nearly crushes Gumball, and freaks them out. Richard creepily says that he's going to prank them, then goes crazy. Gumball and Darwin, realizing that Richard has gone insane, frantically sprint to the bathroom upstairs and hide in the bath tub. Gumball starts hyperventilating, which causes Darwin to try to slap him out of it. Gumball panics more and yells at Darwin that he's making it worse. Darwin decides to use tenderness to calm Gumball down, and this seems to work. He strokes, hugs, and kisses him to make him feel better. After a moment of silence, Richard busts through the bathroom wall and declares all out war against Gumball and Darwin by yelling "PRANK TIME!". The boys run to the living room and hide under the sofa, and Richard busts through the ceiling and asks "Where are you?", but Darwin gives their position away, so they hide inside the TV. Richard spots them, forcing them to act out TV shows to stay hidden. They act out a news show, a classic retro romance show, a documentary, and a music video. This proves fake, though, because Richard knew they were there the whole time, Richard unplugged the TV while they were still acting. The warpath continues for a short time before Gumball tries escaping through the air vent. Unfortunately, it was nailed in, not only does this doesn't work, it leaves the two of them cornered, giving Richard the chance to finally get them. Gumball, spotting a bottle of ketchup, decides to try to use it as a weapon. When he squeezes, instead of squirting ketchup at Richard, the side facing him bursts open, splattering the boys with ketchup. Richard laughs at them and reveals that all this (the ketchup, his psychotic behavior, and his intentions to kill them) was all part of his prank. Gumball and Darwin find it terrible and accuse him of trying to kill his own kids, but Richard points out that the cement was wet when he poured it into the bucket. The 2 sides apologize to each other; Gumball and Darwin apologize for taking the pranks too far, and Richard apologizes for starting the prank.
Suddenly, Nicole enters the house with Anais. Nicole and Anais look shocked at the huge mess left behind from the chase. Nicole angrily asks "WHO DID THIS?!", causing the guys to all blame each other, ending the episode.
In the TV scene, there's a VHS tape that is labeled "Wrestling" with a few letters crossed-out before it. In "The Club", it's revealed that this is the tape that used to contain Nicole and Richard's wedding video, until Richard taped over it.
This is the second time Richard says something is "only funny when it happens to someone else". The first time was in "The Ghost".
This is the second time Gumball and Darwin were tricked by Richard. The first time in was "The Laziest".
The commercial heard in "The Responsible" is heard again in this episode, when Richard comes back from the sea.
This is the third time in the series Richard seen in his underwear.
