Rigby's taller, younger brother shows up at the park to fix an audit.
Mordecai and Rigby are pretending they are playing football when Benson yells at them to go outside for an emergency meeting. Benson says that the park is being audited because Pops tried to pay the park's taxes with lollipops instead of paying with actual money. After supposedly firing Muscle Man, having gotten sick of his "My Mom" jokes, Mordecai offers a suggestion; Rigby's accountant brother, Don. Rigby does not like this idea because he's hated Don ever since his sixth birthday party, when Don stole the attention of Rigby's friends. Despite Rigby's objections, Mordecai brings Don to the park, where he immediately takes the attention from everybody because he is cool, nice, funny, and the total opposite of Rigby, and also because he gives a hug/hand-shake, which he calls "sugar." Rigby's hatred for Don however grows, and it goes far enough that he mocks Don and throws a football in Mordecai's stomach when he was shown hanging out with Don.
Eventually, when Don is almost finished with the taxes, Rigby then drives Don away by saying that Don should never have been born. Mordecai finds out and tells Rigby to bring Don back, but Rigby refuses to and says he can finish the audit by himself; however, he does it wrong and the park begins to magically disappear by the audit. Benson and the others try to get Rigby to bring Don back, but Rigby's frustration is too strong. Mordecai tells Rigby that although he doesn't have a brother, he feels Rigby is like a brother; that despite how annoying and immature he can be, he can at least make due with him. This gets Rigby to go with Mordecai to Don's house in order to bring Don back, but Don is too sad to go back and questions why Rigby doesn't like him. Mordecai tells him it's because he ruined Rigby's sixth birthday, but Rigby explains that it's not just that, it's everything; he's felt overshadowed by his brother; that everything Don does is better; and that everyone believes Don is the older brother when in reality, Rigby is the older brother. Don apologizes and explains he was just trying to be like Rigby, because he believed everything Rigby did was so cool. Following this reconciliation, they go back to the park in order to stop the audit. Don is almost finished with the audit, but says that Rigby still needs to give him some sugar, so Rigby reluctantly does so under pressure. The park is restored to normal, and Don says good-bye, saying "an accountant's work is never done." Rigby and Don are now on better terms with each other.
