Mordecai, Rigby, and Eileen plan a party for Margaret, who may be transferring from junior college, and must contend with the ghosts of 1980s DJs who consider the park's ballroom a sacred ground.
- Continuity Nod: "Hanging with Margaret" is heard again as Margaret's ringtone, which she made in "Butt Dial".
- Dance-Off: Mordecai, Rigby, and Eileen versus the 80s ghosts for the right to host a party in the ballroom.
- Gilligan Cut: Eileen hopes Muscle Man won't invite people the park workers don't know to the party. Sure enough, he and Hi Five Ghost are throwing all the fliers to a crowd of people from the cart roof.Muscle Man: Hey completely random strangers, come to this chick's party!
- Luminescent Blush: Margaret does this twice during her phone call with Mordecai, showing the audience she's started liking him back.
