in the kitchen, Rigby has a lot of stuff on the table. "You're probably wondering why I brought you both here today." Rigby said. "Not really." Mordecai said. "Sort of." (Y/n) said. "Check it. All the richest people in history have drinks named after them. Shirley Temple, Arnold Palmer, John F. Lemonade. What drink's gonna make me rich you ask? I'll tell you what." Rigby fixes up a drink. "One can of RadiCola, frozen fruit juice concentrate, a dash of hot sauce..." Mordecai and (Y/n) look disgusted. "Sugar Roasted Sugar Bombs for texture, and the rest..."

Rigby adds some fruits and fish bones, followed by pickles. "Mordecai, witness The RigJuice!" Rigby said. "I... really don't think you should drink that." Mordecai said. "It's like if coffee and nightmares had a baby." (Y/n) said in disgust, and Mordecai snickers. Rigby drinks his RigJuice, then coughs wildly, and (Y/n) cringes. "Whoa... my face feels like magic. Either of you wanna taste?" Rigby asked. "I think I'm good." (Y/n) said. "Pfft, yeah right. I'm not dumb enough to drink that stuff." Mordecai said. "Come on, we do dumb stuff all the time! We're like two peas in a pod." Rigby then looks at (Y/n). "Three, technically." He said.

"Uh, no.. I'm definitely smarter than you." Mordecai said. "And I'm smarter than both of you combined." (Y/n) smirks at them, and they glare at her. "Oh, I must have missed the part where intelligence was measured by arrogance." Rigby snapped, and Mordecai snickers, as (Y/n) glares at Rigby. "Well it's a good thing I didn't miss the part where being a jerk wasn't considered a desirable trait." (Y/n) said. "Why you!-"

Rigby tries to charge at her but Mordecai quickly separates the two. "Okay, you two, enough!" He shouted. The raccoon and chipmunk glare and growl at each other, before pouting and looking away with with their arms crossed, and Mordecai sighs and face palms. "Look dude, it doesn't matter. Either way, I'm definitely smarter than you. It's been that way ever since you dropped out of high school." Mordecai said.

"Dude, what? I don't need no high school education. You can't use everything from school in everyday life." Rigby said. "I guess that explains why you're still struggling to form a coherent sentence." (Y/n) said, and Mordecai laughs, and Rigby growls in frustration. "Ugh! I hate you sometimes!" He snapped. "The feeling's mutual!" (Y/n) shot back angrily. Mordecai sighs. "Dudes, enough." He said.

Benson walks in with some tools. "Hey, (Y/n), Mordecai and Rigby. I got a question for you. You know those six box turtles at the park petting zoo? Each of those turtles needs a turtle fence. Assuming each turtle needs nine square feet of space, I need you guys to figure out the minimum number, of nine foot planks to use for construction." Benson said. "Uh..." Rigby said in confusion. "Whoa, Whoa, slow down, Benson. Rigby can't answer that question. He doesn't have a high school diploma." Mordecai said. "You don't have a diploma? Thanks for wasting my time. Where's Skips? I'll go ask him." Benson said. "Ask Skips what?" Muscle Man asked. "Oh, just about some math problem that Rigby doesn't know how to solve." Mordecai said. "STOP TALKING!!! Just because I couldn't solve some math problem, doesn't make you more smarter than me!" Rigby said.

"More Smart", not "More Smarter" (Y/n) corrects, and Muscle Man snickers. "Didn't you learn that in high school?" Hi Five Ghost asked. "LEARN THIS!! A high school diploma never got nobody nothin' and that's a fact!" Rigby shouted. A horn honks as a Burger Bros. truck stop by. "Free Burgers! Free Burgers for all high school graduates!" An employee said. "Whoo! I'm a high school graduate! I got my diploma right here!" Muscle Man said. "Yeah-yuhhh!" Mordecai said, and Pops laughs. Everyone else except Rigby and (Y/n) line up for burgers, as Rigby watches from the computer room window in shock. He then glares at (Y/n),

knowing what she was about to say. "Not. A. Word." Rigby said. Rigby then writes a fake diploma, dashes out of the computer room, and runs outside. "NOOO!" The trucker closes and leaves. "Wait! I've got my diploma! Come baack...!" Rigby shouted. "You misspelled "Diploma" dude." Mordecai said. "Huh?" Rigby looks at fake diploma seeing he spelled it like "Diplowma" That's it! I'm going back to high school!" He said. "Eh, doesn't sound like a good idea to me. Our friendship wouldn't work if we're both smart." Mordecai said. "What? What are you talking about? We're both the same amount of smart as each other!" Rigby snapped.

"No, you're not. I'm smart too, and you're my friend. That's our dynamic, dude. I have a high school diploma and you don't." Mordecai said. "I'm gonna get my diploma, and then we'll see how you like being the dumb one!" Rigby shouted. At Rigby's old High School, a bell rings. "Well, class, this is quite possibly the hardest math problem in the world, whoever can solve it, will be leaving the classroom today with a diploma in their hands." The teacher said. Many students whisper Rigby's name, thinking he'll try to solve it. "Did you say diploma?" Rigby asked. Rigby walks over to the chalkboard and solves the problem. "That...is correct!"

The teacher gives Rigby his diploma. "Congratulations, Rigby, you won't need to go near another school for the rest of your life!" He said. "OOOOOOOOOOOOOOOO-" Rigby and the teacher said. As it turns out, Rigby was asleep, with drool on his face. "Oooooooo-" Rigby said. "RIGBY!" The teacher shouted. "Huh? Wha?" Rigby asked. The class laughs, and the teacher is not amused. "Uhhh...Can I get my diploma now?" Rigby asked. "Get out of my class, Rigby." Back at Pops's house, Mordecai and (Y/n) are playing video games, and Rigby starts walking up the stairs. "How was school, Rigby?" (Y/n) asked. "Uh.... It was... fine." Rigby said. "You fell asleep in class, didn't you?" (Y/n) asked with a smirk.

"SHUT UP!" Rigby shouted. "You wouldn't fall asleep so much if you had your High School diploma." She said. "Grrrr!" Rigby goes to the computer. "The lousy High School diploma. I can get my diploma the easy way, online." Rigby said. "Welcome to the Education Mentor. Get your diploma now by taking our online test." A voice on the computer said. "Hmm! Hmm! I got this. Bam!" Rigby said. "First question: Which of the following is not a square?" The voice asked. "Gah... This is too hard." Rigby throws his chair while screaming in rage, he starts shaking the computer. "I WANT MY DIPLOMA!" Ads come up as a result of his rage.

"Ugh! Ads, go away, now!" He starts closing ads, but he rests on one. "Huh? BrainMax? Increase your intelligence? More smarter." Later Rigby is opening his BrainMax. "Welcome to the BrainMax system. Instructions: Take one tablespoon a day. Do not take if pregnant, or one hour after heavy thinking. Will see results in thirty to forty days? What?! I'll just drink a month's worth of doses, I mean it doesn't say not to." Rigby drinks the BrainMax. The bottle says "Use Only As Directed". Rigby groans as his head starts pounding. Plenty of scientific words go inside Rigby's brain. "Whoa." Rigby looks at the Computer. "I know this now.

Wait a minute. I know everything." Rigby said. Later in the living room, Rigby is doing a 'Smart Guy Quarterly crossword puzzle when (Y/n) and Mordecai come in. "Wait, are you doing a crossword puzzle?" (Y/n) asked in surprise as she looks over. "I sure am." Rigby said. "Hey, I know something that can help you with that crossword. It's called a high school diploma." Mordecai said. "All merriment aside. Perhaps you can assist me with this. What's an eight letter word for idiot?" Rigby asked.

"What the...? Rigby are you okay?" (Y/n) asked, getting worried. "Yeah, why are you talking like that?" Mordecai asked. "I tried "imbecile", "bonehead", "pea-brain", Oh wait! I got it. "Mordecai" Rigby said. 'Oh boy...' (Y/n) said. "You're the idiot, you..." he counts his fingers to see how many letters the word has before he says it. "Dumb-face!" Mordecai shouted. "Hmm. I'm afraid while "dumb-face" fits, it's simply too stupid for this puzzle. Face it Mordecai, I'm the smartest now." Rigby said. Rigby drinks the BrainMax. "What is that? That isn't RigJuice" Mordecai said.

(Y/n) takes the BrainMax out of Rigby's hands. "BrainMax?" She asked. Rigby tries to get it back. "Get your hands off that! Gimme that!" Rigby said. "Rigby! How much of that have you been drinking?! It's bad for you if you have too much at once!" (Y/n) shouted. "You're not my mother, (Y/n)! Give it back!" Rigby shouted, trying to reach for it, and Mordecai snatches it from (Y/n). "Mordecai!" (Y/n) scolded. He laughs and takes a sip and now feels pain in his head, shocking Rigby and (Y/n). "Mordecai!" (Y/n) shouted again, this time worriedly. "First of all, I wanna contradict your earlier statement." Mordecai writes a math problem on the living room window.

"This theory proves you're dumber than me." "Ha!" Rigby takes the BrainMax away from Mordecai and takes a sip. "As you can see by my encounter theory, it is you, that you are dumber than me." Rigby said. "Guys, stop! This is getting out of hand!" (Y/n) shouted, but they ignore her. Mordecai takes the BrainMax away. "Tsk. Tsk. Wait till you see my 20 page research paper backing up my theory." He said. Rigby takes the BrainMax away. "Tsk. Tsk. I'm gonna write a 21 page paper backing up my theory. AND prove yours wrong!" Rigby said. "Tsk. Tsk. Is that so?" Mordecai asked. "Tsk. Tsk. Yeah!" Rigby said. "Guys, stop!" (Y/n) reaches for the BrainMax, but Rigby shoves her back, catching her off guard. "Stay out of this, (Y/n)!

You don't know what it's like to have someone make fun of your level of knowledge!" Rigby snapped. "Oh I don't?! You do that to me all the time, Rigby! Seriously, this whole petty argument you guys are having is stupid! Who cares who's smarter than the other?! You're friends! Isn't that all that should matter?" (Y/n) snapped. "Nope." Rigby said simply, crossing his arms. "Ugh!" (Y/n) angrily leaves the room. Mordecai and Rigby are saying "Tsk. Tsk" repeatedly. The duo try to prove each other that they're smarter than each other by drinking more BrainMax and putting many more theories around the house with corrections and writings everywhere.

Mordecai and Rigby are in a room, where more words are going through their head. "In closing, your theories had failed to prove that you're smarter. For your brain is no bigger than a walnut." Mordecai said. The word 'walnut' hits Rigby. "Very funny Mordecai, but your paper is fundamentally flawed because your brain is made of 99% canine butt cheeks." Rigby said. The words 'butt cheeks' hits Mordecai. "There is still one irrefutable truth. You don't have a High School diploma, so I'm smarter than you, you imbecile." Mordecai said. The word 'imbecile' then hits Rigby and suddenly takes away the background of the house.

"GAHH! I am not an imbecile!" Rigby opens the door to the computer. "If a diploma will prove that I'm smarter than you, than so be it!" He is confused and sees the computer differently. "Huh? Ahh! I can't read it!" He shouted. "Probably because you're still too stupid." Mordecai comes to the computer. "Here. Huh? What kind of writing is this?" He asked. Back in the normal world (Y/n), Benson, Skips and Pops come in to the room where all their theories were shown. "Oh god..." (Y/n) said worriedly.

"Mordecai. Rigby. (Y/n) told me what's been going on and- huh?" Benson sees the theories they did. "AHH!" Mordecai, Rigby, get downstairs right now," Benson turns red. "And clean down the mess you made, or I'm gonna fire-" Mordecai And Rigby don't know what Benson is saying due to the BrainMax they drank. "Dude, what is he saying?" Rigby asked. Both of them see them differently as what they're saying and how they look. Making them looking like caveman-like creatures. "Oh no. We've become so smart, they're stupid to us." Mordecai said. Then (Y/n) tries to say something to them but they don't understand her either. "(Y/n)? (Y/n)?! We can't-" Rigby said, starting to panic. She keeps talking. "Aw, man! We can't understand a word she's saying!" Mordecai said.

In the normal world, (Y/n), Benson, Skips and Pops hear Mordecai and Rigby in Latin and glance at each other awkwardly. "Oh no! This is not good!" Rigby panics, then turns to glare at his friend. "If you haven't made fun of me so much, none of this would've happened!" Rigby shouted. "Whatever. You can't even get your diploma, because we're so smart. So, what's the point?" Mordecai asked. "You're right. There is no point." Rigby said. "Huh?" Mordecai asked. "What's the point of being so smart, if you can't even understand anyone? Especially (Y/n)? I don't want to lose her, dude." Rigby said. "Why do you care? You're the one who's been a big jerk to her recently."

Mordecai said. "You fight with her all the time!" Mordecai shouted. "Well (Y/n)'s the one who always starts it!" Rigby shouted, and Mordecai narrows his eyes at him. "Oh really?" He asked in disbelief, and Rigby huffs, then crosses his arms. "Okay, maybe she doesn't start them ALL the time. Look, I may fight with her sometimes but she's still my other best friend, I can't lose her." Rigby said. Mordecai sighs. "Yeah, me either." He said. "We have to get stupid again." Rigby said. "How?" Mordecai asked. "...RigJuice." Rigby said. "The fridge!" Mordecai and Rigby float to the fridge.

In the kitchen, Muscle Man and HFG are shaped differently, with Muscle Man shaped like a manatee whilst eating pie and Hi Five Ghost in a blob appearance. Rigby opens the fridge to find the RigJuice. "Ah ha! The RigJuice!" Rigby said. "Pour me some." Mordecai said. Rigby pours the RigJuice to his cup which shows how the material is made out of. "Whoa... It looks... different now." Rigby said. "Ready?" Mordecai said. "To being stupid. Bottoms up." Rigby said. Mordecai and Rigby make the toast and drink the RigJuice. Little silence appears again to see what happens. "..Did that work?" Rigby asked. Suddenly, Mordecai and Rigby fall and scream while falling and their intelligence starts to go away when (Y/n) and Benson appear normally now.

"And if you don't stop goofing off and clean up this graffiti now, I'm gonna tear you limb from limb!" Benson shouted. "Huh...?" The duo asked. "What just happened...?" Rigby asked. "Uhh...I don't remember anything..." Mordecai said. "Me and Fives were practicing for our pie-eating contest, when you two dweebs came in speaking Spanish or something." Muscle Man begins to eat his pie again. "Then you drink that green stuff." Hi-Fives said. "Ugh! I can't believe you got me to drink your lame drink." Mordecai said. "Better get started, or it's coming out of your paycheck." Benson said.

"Yeah, losers." Muscle Man, High-Fives and Benson leave the room. (Y/n) clears her throat and the duo look at her, and Rigby laughs nervously. "Uh, h- hi (Y/n)." He said. She raises an eyebrow. "Are you two done arguing about this silly subject now?" She asked. Rigby laughs nervously again. "Yeah, we're done. We're sorry, (Y/n)." Rigby said, and she sighs. "You better be. I was really worried about you guys." She said. "You know, maybe if you had a High School diploma, we wouldn't be in this mess." Mordecai said. "Mordecai!" (Y/n) shouted. "Well, guess what? This drop out somehow got you to drink RigJuice." Rigby said. Mordecai gets up and awes. "... I'll get the paint." He leaves the room, and (Y/n) sighs. "You two will be be the death of me..." She said.
