Plot summary
The crew cater a backstage party for rock star Jackal Onassis ( Jimmi Simpson ). Casey returns to the team after Henry fires an employee ( Danny Woodburn ) for being late and drinking on the job. Jackal Onassis switches place with Roman, acting as a bartender named "Dennis", so he could feel like a real person, after admitting everything in his life is fake. Even though Roman is dressed in Jackal Onassis' wardrobe and people think he is him, he still has no luck with the women there. New member of the team Lydia ( Megan Mullally ) tries to help Casey in dealing with the awkwardness of being back on the team and around Henry.
Henry learns that Casey is dating someone and she finds out he is dating Uda. Ron comes to the backstage party with his new girlfriend Mandy ( Aviva ), who is a big Jackal Onassis fan. After Ron finds out Roman (dressed as Jackal) signed his girlfriend's breasts, he attacks him, causing security to taser Ron. Henry then gets in trouble when security finds out Ron and Mandy were allowed in uninvited. "Dennis" then takes the blame, letting Henry fire him. Ron asks Henry if he can get Alan Duk to give him his job back after it is revealed his "Soup 'R Crackers" franchise failed.
