"The Return" (originally titled "Oscar's Return") is the fourteenth episode of the third season of the American version of "The Office", and the show's 42nd overall. In the episode, the office celebrates Oscar Martinez's (Oscar Nunez) return, who had been on vacation since the first episode of the season. Meanwhile, a recently departed Dwight Schrute (Rainn Wilson) finds a job at Staples. The episode was written by Michael Schur, Lee Eisenberg and Gene Stupnitsky, and was directed by series creator Greg Daniels. Actor Oscar Nunez returned to "The Office" after having left to film the television series "Halfway Home". The annoying personality of Ed Helms's character Andy was noted by multiple observers, and even irritated the actor's own mother to such a degree that she could not watch the episode.
