Don

(Y/n), Mordecai and Rigby are playing football in the living room. "(Y/n)! I'm open, I'm open, (Y/n)!" Rigby called to her, and she snickers. "Go long, dude!" Rigby is sent flying backward off the couch when she throws a ball of socks at him. "Touchdown, sock faces!" He throws down the socks and begins imitating cheering. Just then, Benson enters. "Hey, you three! Quit fooling around; we're having an emergency meeting." He said. "Aw, what?" Mordecai asked.

"Boooo." Rigby whined. "What for, boss?" (Y/n) asked. He gestures towards the door. "I'll tell you. Outside, now!" He said. He leaves as (Y/n), Mordecai and Rigby watch. Later, all the park workers are standing outside. "Alright, everyone. I got some bad news. The park is being audited." Benson points to Pops. "Pops tried to pay the park taxes..." he gives him a look. "...with lollipops." And (Y/n) snickers. Benson turns to glare at her for a moment before sighing and turning back to everyone. The workers voice their displeasure.

"But I gave them more than enough." Pops said. "We already went over this, Pops. You pay taxes with money, not lollipops." Benson said. "Oh." Pops said dejectedly. "What's the big deal? It's not like an audit is a bad thing." Rigby said. "Rigby, it is a big deal! If we don't take care of this, the government takes our stuff away." (Y/n) said. The rest of the workers panic. "Exactly. Thank you, (Y/n). Okay, we only have till three to stop the audit." Benson said. "Does anyone know someone who can help us? Anybody? Anybody at all?" Benson asked.

Muscle Man raises his hand in the air. "I know someone who can help." He said. "If you say your mom, you're fired." Benson snapped. Muscle Man frowns for a moment, but a goofy smile appears a minute later. "MY MOM!" He said. "GET OUT!" Benson shouted. "It was worth it!" Muscle Man and Hi Five Ghost hi five and run off. "Was it? Now you're jobless." (Y/n) said, and Mordecai and Rigby snickered.

"Hmmm... Hmph. Hey!" Mordecai looks at Rigby. "We know someone." He said playfully. "We do?" Rigby asked him. Mordecai raises his arms, and Rigby recognizes the person Mordecai is referring to. "No! No way!" He said stubbornly. "What? If you know somebody, you've got to tell me." Benson urged. "Rigby has a brother." Rigby punches Mordecai. "And he's an accountant." Rigby punches Mordecai swiftly. "Shut up!" Rigby shouted. "Rigby, what's wrong?" (Y/n) asked. "Yeah dude, what do you have against Don?" Mordecai asked. Rigby gets mad, on the verge of crying.

~flashback~

"Guys! Guys! Guys!" Young Rigby said. Five bored children, including a young Mordecai, are sitting there. "Watch me blow out the candles, guys!" A door opens. Rigby's younger brother, Don, stands in the doorway. Somehow, he is taller than Rigby. "Hey, Rigby. Happy birthday, bro." Don said. Rigby gets mad. "Wha? Wha? I told you to stay in the basement!" Rigby snapped.

"Oh. Sorry, Rigby. I just wanted to give you some birthday sugar." Don said. "I don't want your freakin' sugar!" Rigby snapped. "I'll give you some sugar, Don." One of his friends said. "Yeah, me too." Everyone gets up out of their seats to hug Don. Then, Mordecai follows, but Rigby tries to stop him by grabbing his arm. "Don't you dare!" He shouted. "Rigby it's okay, I'm just getting some sugar. Besides, Don is cool." Mordecai goes to Don to give him sugar as everyone else laughs. "You're the best, Don!" Rigby growls.

"Yeah. Don really made that party." Mordecai said. "Call your brother!" Benson shouted. "No!" Rigby snapped. "Call your brother!" Benson repeated. "No! I hate him!" Rigby shouted, still refusing. "Fine. Mordecai, you call him." Benson said. "You better not!" Rigby shouted. "Rigby, come on! He could save the park!" (Y/n) insisted. "(Y/n), he could ruin my life! If he comes, I'm gonna tell him to leave!" Rigby shouted. Benson walks up to Rigby. "No, you won't! You be nice to your brother or you're FIRED! Call him." He walks off. (Y/n) leans down and pats him gently. "Rigby, just be cool until he stops the audit." She said, he just growls.
