(Y/n), Mordecai and the Rigbys

Rigby enters The Coffee Shop and is carrying a big box. "Dudes! Check it out, man! They're here!" Rigby said. "What's here?" Mordecai asked. "Our fake band t-Shirts that we ordered from that site last night." Rigby said. "What?" (Y/n) asked. "Last night, I asked you both if you wanted to be in a band and you said..."

~flashback~

(Y/n), Mordecai and Rigby are pounding sodas at the computer. "Yes, I wanna be in a band with you. " Mordecai said. "Me too, sounds cool." (Y/n) said. "Alright, but we gotta have a cool band name. What do you think of "Cool Dudes"?" Mordecai asked. "Um, did you forget I'm part of the group?" (Y/n) asked. "Oh, yeah. Um..." ""Face Punch." Rigby said. ""Rad 'N' Subtract." Mordecai said. "Helicopter Crash." (Y/n) said. "What about Cash Stash"? Mordecai asked. "That's it! That's it!" Rigby said. "Order the shirts! Order the shirts!" (Y/n) said.

~present~

(Y/n) face palms. "Aw man! I can't believe I said that! Your idiocy must be rubbing off on me." (Y/n) mumbled. But luckily for her, neither of them seemed to have heard that. "Oh yeah, T-Shirts." Mordecai said. "Check it out. Bam!" Rigby pulls out a "(Y/n), Mordecai and the Rigbys" t-shirt. "(Y/n), Mordecai and the Rigbys? What happened to Cash Stash?" Mordecai asked. "I changed it. Awesome, right?" Rigby throws a t-shirt at Mordecai, then at (Y/n). "But that's just our names. We aren't really going to wear these around, are we?" (Y/n) asked. Rigby puts on the shirt and (Y/n) looks at him disapprovingly.

Sam suddenly walks up. "Woah, rad shirts! What are those for?" He asked. "They're for our band." Rigby said, (Y/n)'s eyes widen and she slaps him for lying. "Ow!" Rigby glares at her as he rubs his arm. "You guys are in a band? "(Y/n), Mordecai and the Rigbys"? That's so cool." He said. "No, no, no, we're not in a band, heh..." (Y/n) said. "So, what, it's some sort of fake band?" Sam asked skeptically. "No, it's a real band, but just... not a big deal, you know?" (Y/n) asked. Sam gasps. "Your band should play the open mic tomorrow night." He hands (Y/n), Mordecai and Rigby a flyer. "Yeah, for sure, uh... totally." (Y/n) said. "Awesome. I can't wait to see you guys play. Well, I guess I'll see you then. He walks away and Mordecai and Rigby glare at (Y/n) who chuckles nervously. "What was that for (Y/n)?

Uncool! First you hit me for lying to him, then go and do it yourself you big hypocrite!" Rigby snapped. "Okay, first of all, you're one to talk when it comes to being a hypocrite, Rigby. And secondly, I don't know what happened! I just didn't want him to think we had a stupid fake band!" She shouted, glaring at Rigby. "Well congratulations, he doesn't now." Mordecai snapped. (Y/n) crosses her arms with a huff. "What is with you two? Why do you always act so childish whenever he's involved?" She asked, glaring at her best friends as they glared back.

"Childish? You're the one who just lied to him just to impress him!" Rigby snapped. "Yeah, (Y/n). We're not childish, okay? We just don't like the guy." Mordecai said. "Why?" (Y/n) asked. "We have our reasons." Rigby said. "Care to tell me what they are?" (Y/n) asked. "Nope." Rigby looks away from her. (Y/n) just rolls her eyes. "See? Childish." Rigby turns around and glares at her. "Why you...!" This is when Mordecai steps in and gets in between them, holding Rigby back from attacking her as she sticks her tongue out at him. "Guys, stop fighting!" He scolded. "But now we gotta play that open mic tomorrow!" Rigby shouted. "OK, OK, we can totally do this. We just gotta learn one song by tomorrow night." (Y/n) said. "One song?" Rigby asked her.

"One song." She replied. Later, Inside the garage, (Y/n), Mordecai and Rigby turn on their amps, and are shown wielding guitars. "Ready?" Mordecai asked. "Shreddy." Rigby said, and (Y/n) chuckles. "One, two, three, four!" Mordecai said. They fumble aimlessly at the strings, producing distorted noise, and (Y/n) cringes. "OK, stop, stop. We need help." She said. In Pops' room, Pops is playing a beautiful tune on the harpsichord. "A two-man ensemble? What a charming idea!" He said. "How'd you learn to be so good, Pops?" Mordecai asked. "Ah-ha!" Pops rises from the harpsichord bench and pulls out some records from inside. The first is 'How to be a Musician' by 'Sir Geoffrey' "Throw these records on the old talking machine and you'll be ready for your open mic in no time!" He said. "Agh, you know about the open mic night?" (Y/n) asked.
