During Miss Simian'sclass, Darwin is inspecting something with his microscope. After he learned that he was inspecting Banana Joe's butt up close all along, he sees everything with butts on them, panicking that everything is ruined (except for Miss Simian's face, which he says looks better). Miss Simian asks them to pay attention to a chrysalis in a jar on her desk, explaining the life cycle of a caterpillar. She promptly sends Banana Joe to Mr. Small'soffice when Banana Joe flaps his peel "inappropriately" like a butterfly.
When Penny asks if the butterfly can be released after emerging, Miss Simian objects, and tells everyone about the butterfly effect. She demonstrates something like it by causing destructive events in the classroom that ends with a window hitting Tobias' head. Just before she asks them to witness the butterfly's emergence, the class bell rings and she drops her lesson.
Just as Miss Simian and the others leave, Gumball and Darwin see the chrysalis moving and panic. After Gumball takes a hot shower and they both breathe rapidly, the butterfly emerges. The brothers are thrilled by it, and decide to let it free.
At their break time, Hank and George have some coffee. When they toast, their mugs break due to their powerful bodies. When the butterfly from earlier lands on one of their heads, the other tries to smack it off but instead punches his friend to a wall. The two men start unintentionally beating each other, all the while apologizing until George loses his arms, and Hank has his head sent up to the sky towards an airplane. He says hi to his son before falling back down.
The next scene shows Mr. Robinson driving his car. While on the road, he drives slowly and sings much to the annoyance of the workers driving to work behind him. Mr. Robinson does not care, saying he has all the time in the world and that he is retired. Then he starts taunting citizens (like Larry, by taking his parking space, and the Hobo, by tricking him into hitting a pole). In the latter the Hobo shouts after Mr. Robinson, wishing that he would get what he deserved. Hank's head then hits Mr. Robinson, and knocks him out. As the Hobo steals 20 dollars from Mr. Robinson's wallet, a wheel from the latter's wrecked car knocks the Hobo unconscious. The 20 dollars fly away with the wind.
Many citizens in Elmore notice the flying bill, and compete with each other for it. The money lands near Marvin, who tries to reach it. But his fragile body prevents him from doing so, and Marvin repeatedly prevents himself from falling down with his cane. The Doughnut Sheriff shows up, and fines Marvin 20 dollars for street dancing without a license. When the officer tries to take the bill he rolls down the street and hits a pole, sending one of his shoes flying.
Nearby, Alison feeds the pigeons, then feeds on one of them. When Rocky passes by with a bagel, the shoe hits him and makes him inadvertently lean to Alison with the bagel held as if it were a wedding ring. Alison sees this and accepts Rocky, thinking he was proposing marriage. After the old woman explains her sacrifices for the "moment," Rocky says he "changed his mind" and tries to disappear. He ends up hurting himself, and Alison calls the Elmore help desk.
At the Elmore help desk office, Karen receives Alison's call saying she was abandoned by her fiancé. As they sing/talk, Rocky also calls Karen saying that a crazy lady alligator wants to be his bride. Marvin also calls, and says that he (still being stuck with the 20 dollars) will need help standing straight. Mr. Robinson also calls, shouting that he wants to sue whoever made him wreck his car. Karen gets angry with his attitude, and Hank's head calls too. After they make her angry with all their issues, Karen hangs up on all of them and throws her desk out of her office.
The desk causes cars to crash into each other, and people to topple over. The people create a domino effect which ends when Hector falls on Sussie'sdad. He sneezes, and this causes Charlie to be blown into a roundabout. Rosie nearby panics when the roundabout spins so rapidly that a small tornado materializes. But she calms down when the tornado disappears, and Charlie is launched into the sky. He lands in the Wattersons' TV while the weather news is on, causing a tornado to form and Richard to be sucked in it.
Back at Elmore Junior High, Miss Simian returns from her break. She is shocked when she sees that the butterfly is gone. Gumball and Darwin freely admit that they were the ones who did the "decent thing," and released the butterfly. Miss Simian gets frightened, and takes cover. The butterfly comes back, and Gumball wonders how something so tiny could destroy a whole town. He gets his answer when the butterfly flies away from his view, and reveals a tornado that heads towards them.
The butterfly effect is a real principle in chaos theory, the classic example of which theorizes that a butterfly flapping its wings can alter the path of a tornado, or even cause one through a domino effect. This theory was made popular by the film named after it.
The scene where a bill flies and the music that accompanies it is a reference to Forrest Gump.
Marvin is seen standing at the corner of the block throughout most of the episode, unable to move. However, he later appears in the mall.
A similar incident happens with Harold; he is seen about to board a bus, but is seen not too long after in a line outside the mall. Felicity is also seen on the plane, and later she is seen fighting for a 20 dollar bill. Donald is also seen being knocked over at the entrance of the mall, but seconds later he is seen on the escalator, getting knocked over again.
The sign at the "Emergency Call Centre" uses the British spelling of the word "center," even though Elmore is an American town.
Although five people called Karen, only three telephones are picked up. However, this error eventually corrects itself.
[Episode starts with the close up of something through a microscope.]
Darwin: Hmm. Is it a leaf?
Gumball: [Amused; snickers] Nooo.
Darwin: Is it a really small sandwich?
Gumball: [Amused] Nooo!
Darwin: It looks like a yellow eye, but closed.
Banana Joe: Nah! [Zooms out to show him, Gumball and Darwin in class] It's my butt!
[Gumball and Joe laugh while Darwin screams.]
Darwin: It's imprinted on my eyes! Everything is ruined! [Looks at Leslie, whose face is now a butt] Nature is ruined! [Looks at wedding couple whose faces are now butts] Love is ruined! [Looks at a cropped image of The Creation of Adam where God and Adam's fingertips are butts] Art is ruined! [Screams] Even Miss Simian is ruined!
Lucy Simian: What you are looking at is called a chrysalis. [Points to said object in a jar] The caterpillar wraps itself up inside, and emerges as a beautiful butterfly.
Banana Joe: Like me. [Peels flap] Ah!
[Gumball and Darwin snicker at him.]
Lucy Simian: Joseph, we've been here before. When is it appropriate to take your skin off?
Banana Joe: Uh… Christmas!
Lucy Simian: [Points to door] Counselor's office.
[Banana Joe sighs, and flies away with his peel flaps.]
Penny: So when it's a butterfly, can we release it from the jar?
Lucy Simian: Are you crazy? Hasn't anyone heard of the butterfly effect?
Tobias: Oh yeah. [Dances. This gets Penny's attention] It's my chick-magnet dance move.
Penny: Oh! That works really well with my dance move.
[They laugh and dance.]
Tobias: Nice, girl! What's that move called?
Penny: The bug spray.
[They stop dancing, and Tobias dances away, sad.]
Lucy Simian: Enough! The butterfly effect is a theory according to which the smallest thing -- such as a butterfly flapping its wings -- can create a series of events leading to a catastrophe, such as a tornado.
Darwin: Hmmm. How does that work?
Lucy Simian: Like this.
[She flicks her chalk into the ceiling fan, and it bounces off, hits another chalkboard, bounces off again, and sends a chalk eraser flying. The eraser hits Miss Simian's mug's spoon, and sends some coffee flying to Bobert. Bobert gets electrocuted and shuts down, and when he explodes a nut flies toward the window. The window falls on Tobias' head while he attempts to flirt with Carmen.]
Lucy Simian: But more complicated. [As if in awe] Now, I want you to gather all around my desk, and [Grabs jar] witness the true beauty of nature as the butterfly emerges from its-
[The bell rings.]
Lucy Simian: [Disinterested] And I'm off the clock and don't have to pretend to care about your education. Coffee Break.
[Everyone walks out of the room, with Gumball and Darwin following behind. As they pass by Miss Simian's desk, the chrysalis begins moving. They start panicking]
Gumball: The baby is coming! Someone call 911!
Darwin: [Slaps Gumball] Calm down! We need a towel, and some hot water.
Gumball: Of course! I'll be right back. [Goes out of classroom, then quickly comes back dressed in only a towel (on his head).] Ah! You're right. Nothing better than a hot shower to- [Gets slapped with his own towel by Darwin] AH!
Darwin: Not for you, for him!
Gumball: What would he wanna do with hot water and a towel?
[The butterfly starts emerging.]
Gumball: Ah! He's coming! OKAY! Breathe like this. [Breathes rapidly]
Darwin: [Breath rapidly]
[Their faces get red; they both faint for a while. The butterfly falls out of its cocoon, and the two get up. They are smitten by it]
Gumball: I think he needs to get out.
Darwin: But what about the butterfly effect?
Gumball: Dude! How can something this cute be responsible for something as bad as a tornado? It's like blaming baby boomers for the stand of the world. How can babies go in boomer with the economy?
[Gumball grabs the jar, and sets the butterfly free. It flies out the school's window.]
Gumball: Ah. This is the nature of beautiful.
Darwin: [Sees the butterfly's real butt] Eugh. As much as it can get I guess.
[In a construction site, Hank brings two coffees to his mustachioed co-worker and friend.]
Hank: Here you go buddy. [Gives drink] Cream with two sugars, just as sweet as you.
George: [Laughs] Thanks buddy!
[They toast, but their cups shatter.]
George: Oh man, I'm sorry!
Hank: No, not at all. It's my fault. I just don't realize my own strength sometimes. Just this morning, I pat my son on the head. He went straight through the floor.
George: Whoa. Is he okay?
Hank: Yeah, yeah. He called us from China, he's getting the next flight home.
[The butterfly flies around, then lands on Hank's head.]
Hank: … [Screams] GET IT OFF! GET IT OFF GET IT OFF!
George: It's okay, buddy. Don't worry. I'm just gonna push it off. I don't wanna damage its beautiful wings.
[He flicks Hank towards a wall, and misses the butterfly.]
George: JEEPERS! I'm sorry man, I-let me help you up.
Hank: Don't worry, it's nothing.
[He grabs the other man's hand, and accidentally flips him into the wall.]
Hank: Oh man. I'm so sorry! Hold on.
[Once again, he accidentally throws his friend to another wall.]
Hank: Oh man! Here. [Pulls out other guy's arms. He screams]
George: Nah! Don't worry, it's just a flesh wound. [Tries to reach for arms]
Hank: Aw, let me get that.
[George accidentally launches Hank's head into the sky when he pulls himself up.]
Hank: [Body falls down]
Hank: It's nothing!
[His head flies over a plane's wing. He talks to someone in the plane before falling down.]
Hank: Hi Bobby. Tell your mother I'll be home late for dinner.
[The passengers in the plane scream]
Mr. Robinson's Day
[While driving his car, Mr. Robinson sings, ignoring the honking behind him.]
Driver: Hey! Get off the road. I've got to get to work, man!
Gaylord Robinson: I don't care. I have all the time in the world! I'm retired. [Laughs] Yodele-hiii!
[Neck Beard jogs along the sidewalk.]
Gaylord Robinson: [Passing by] Yodele-hi-ho!
[He breaks, then passes by Neck Beard, splashing water from the road onto him.]
Gaylord Robinson: Looks like you needed a shower! [Laughs as he drives away]
[In another scene, Larry slowly drives his car into a parking space. Suddenly, Mr. Robinson drives into the lot. He laughs at Larry as the latter drives away sadly. Mr. Robinson drives away, still singing. He stops by The Hobo.]
Gaylord Robinson: Would you like a ride?
The Hobo: Thank you, sir.
[He reaches for the door handle, but Mr. Robinson drives forward. The Hobo tries again, but again the car lurches forward. For the third time, this happens, and Mr. Robinson chuckles. Then Mr. Robinson drives slowly away, and the Hobo runs after the door until he hits a pole.]
Gaylord Robinson: Well, at least you got closer to your destination. [Laughs and drives away]
The Hobo: Darn you, Robinson! I hope someday you get what you deserve!
[Hank's head falls from the sky, and knocks Mr. Robinson out. The latter's car crashes.]
The Hobo: [Looks at finger] Whoa. [Points at sky] I wish I was rich!
[Mr. Robinson's wallet flies to him. He grabs one bill out of it.]
The Hobo: 20 dollars? Is that the best you can do-? [Gets knocked out by wheel]
[The 20 dollar bill flies away.]
A Series of More Unfortunate Events
[As the bill flies away, many citizens try to grab it, and end up knocking each other down. The bill lands near Marvin. Marvin tries to arch down, but his bones crack as he inches closer. He almost loses his balance, and recovers. He does this numerous times until he gives up.]
Marvin: Ah forget it. [Walks away. He then runs back, and tries to reach for dollar bill desperately]
Doughnut Sheriff: [Runs to Marvin] Freeze in the name of the law!
Marvin: Wait! What am I being fined for?
Doughnut Sheriff: Street dancing without a license. That's a 20 dollar fine.
Marvin: Just… help yourself. [Motions to 20 dollars]
[The sheriff tries to reach for the money, but falls down and rolls down the street. He hits a pole, and one of his shoes flies off. Meanwhile, the Crocodile Woman is seen feeding the pigeons. Then she eats one of them. Rocky passes by with bagel, but is hit by the shoe. He unintentionally leans towards the crocodile woman, with the bagel held toward her. The woman stares.]
Rocky: Erm. Hi.
Alison: [Pigeon flies out of mouth] YES!
Rocky: Mmm. Yes what?
Alison: Yes, I will marry you!
Rocky: [Laughs nervously] Wait, I think there's been a misunderstanding.
Alison: [Wears bagel ring] I've been saving myself all these years for this moment. All that time spent alone, desperate, loveless.
Alison: I was so depressed I couldn't get work. I lost my house, I was forced to live with my cats in a van by the freeway, feeding off squirrels and rust! But it was all worth it. Just for this moment. [Leans for a kiss]
Alison: [Turns to garbage cans] Kid, I'm on the same side of the road as you. I saw you hide behind the trashcan.
[Rocky leaps out, and panics.]
[He throws dust on the ground, and coughs. He topples the trash bins, and leaps over a fenced yard, then gets bitten by dogs.]
Rocky: My arm!
[Rocky prepares to fight the woman, then stops.]
Rocky: That's my weak arm.
[He lies down in the trash, and wraps himself in a trash bag.]
Alison: See you in court, you piece of trash.
[She dials the Elmore Help Desk with a phone nearby.]
Elmore Help Desk
[In an office building, Karen picks up her call.]
Karen: Good morning, Elmore Help Desk! How can I assist you? Alison: I've just been abandoned by my brand new fiancé. Karen: I'm gonna need his details So I can assist you. Alison: I know it sounds unlikely But, I never got his name... [The phone rings; Rocky is calling] Karen: Sorry caller, hold the line! Good morning, Elmore Help Desk! How can I be of service? Rocky: A crazy alligator lady wants to be my bride! Karen: And what is it about herThat's making you so nervous? Rocky: 87 teeth, and a butt that's five foot wide. [Another phone rings; Marvin is calling] Karen: Sorry caller, hold the line! Good morning, Elmore Help Desk! How can I assist you? Marvin: I'm gonna need a bit of help to get me standing straight. Karen: And do you have a wife, sir Or someone else who's missed you? Marvin: I don't, but if you're offering I'll pick you up at eight. [Yet another phone rings; Mr. Robinson is calling. Karen is growing a bit frantic] Karen: 'Morning, Elmore Help Desk! How can I assist you? Gaylord Robinson: I wanna sue the lousy flying head who made me crash! Karen: There is no need to shout, sir I really must insist you— Gaylord Robinson: Our taxes pay your wages, I'm entitled to be brash! [Another phone rings; it is Hank. Karen is freaking out at this point.] Karen: Yes?! Help Desk?! What seems to be the crisis? Hank: An accident has left me very widely spread. Karen: Stay calm and wait for help, sir. That's what my advice is. Hank: I would, but I'm afraid I have an itch upon my head. Karen: [starts yelling]Sorry, caller, hold the line! [She accidentally switches back to Mr. Robinson's line instead of the Crocodile Woman's.] Morning ma'am, I'm back now. I found your lost fiancé. Gaylord Robinson: Who're you calling "ma'am?" This service is appalling! Karen: Sorry, sir, I'm trying! There's no need to be nasty! Marvin: I'd have been back home by now if I'd just started crawling. Karen: 'Morning, Elmore Help Desk— Rocky: Stop that crazy gator! Alison: Again I am a crocodile! I'm eccentric, I'm not mad! Rocky: Oh, boy... Hank: Can someone scratch me? Marvin: I think I'll call back later. Gaylord Robinson: I'll have your job for this! Rocky: Wait a sec, is that my dad? Karen: [extremely angry]OK, enough already! [says each line as she slams a phone onto its receiver] [To Mr. Robinson]You need some manners! [To Rocky]And, you need a life! [To Hank]You need some standards! [To Marvin]And, you need a wife! [To the Crocodile Woman]You need a pay-off! Now, I need a day off!
[She throws her desk out the window. It knocks down some garbage bins, and causes some cars to bump into each other.]
[A car bumps into another trash can, and the can knocks down a line of people, creating a domino effect. The effect spreads through a mall, into the Elmore Stadium, and ends with Hector falling on Sussie's dad. Hector sneezes, and this causes Charlie to be blown into a roundabout. The roundabout spins so fast a tornado begins to form.]
Rosie: Oh my gosh a tornado! Everyone get outta here!
[The roundabout slows down, and the tornado dissipates.]
Rosie: Oh, never mind.
[Charlie is launched again into the sky. In the Watterson's house, Richard is seen eating while watching the weather news.]
Weatherman (TV): Well, today at Elmore we'll have highs of 85 degrees, with a light wind coming in from the south, and some scattered clouds.
[Charlie lands in the TV, and causes one of the cloud icons on screen to go upside down. From this, a tornado begins to form. While the wind blows Richard away, he tries to drink his soda, and eat his hot dog. Instead, he crushes his can of soda with his eye, and has the hotdog enter his nose. He tries to turn the TV off, but is blown away, with his clothes stripped away, then spun around repeatedly in his couch.]
Back to School
[The bell rings, and Miss Simian enters the classroom.]
Lucy Simian: Okay. Break time's over. I can't be bothered to take attendance. So if you're not here, please raise your hand now.
