to Michael that her sperm donor was Andy Roddick. "Goodbye, Toby" introduced Holly Flax, played by Amy Ryan, who would go on to become Michael's main love interest. In fact, her return to the series in the seventh season was used by the writers as a way to write Steve Carell out of the series after his contract ended. Ryan gained prominence with her role as Beadie Russell on the HBO series The Wire. The writers of The Office, who were fans of the series, then approached Ryan about appearing in their show. Ryan, feeling that a comedy series would "keep [her] a couple steps ahead of people [and] surprise people" agreed. Holly's character was developed by the writers awhile before the episode was scripted. However, once Ryan began acting on set, Lieberstein explained that "we started to see this really silly side that Amy brought to the character, and [we] found almost like a junior Michael in her. And we all saw it and knew what we had." After the filming of "Goodbye, Toby", the writers were hoping that Ryan would return for the fifth season; the crew had not made a deal with her to film more episodes, but Lieberstein noted that "we knew that she would stay around, or we hoped." The episode also guest starred Melora Hardin, and Robert R. Shafer. The members of Darryl's band are the actual members of actor Craig Robinson's band: Chris Rob played bass, Asa Watkins played drums, and David Sampson played guitar. The Season Four DVD contains a number of deleted scenes from this episode. Notable cut scenes include Michael comparing Toby to the flu, Holly asking Pam if Kevin just ate before jumping in the bounce castle, Jim not sure whether Ryan is going to downsize him, Jim and Pam browsing for apartments online, the revelation that Kevin's band, Scrantonicity played 30 full Police songs during Phyllis's wedding, Kelly watching Ryan's YouTube arrest video over and over again at Jim's desk, Jim asking about the website, and Troy (Noel Potek)—Ryan's drug dealer—showing up in Scranton. In one deleted scene, in which Toby gives a "farewell" speech that is interrupted by Michael, Toby pleads with the Dunder Mifflin staff to continue his fight to have the office checked for Radon; this scene foreshadows the Season 6 episode "The Chump", in which Toby sets numerous Radon test kits around the office.
