With the welcome exception of one Steve Carell, most wouldn't expect a long-running series to go for broke casting major guest stars toward the end of the series, instead focusing on the characters we've come to know and love over the years. It seems 'The Office' will do exactly that however, as legendary sitcom star and comedienne Roseanne Barr will be dropping by Dunder-Mifflin! Find out who Roseanne plays in the last episodes of 'The Office' inside!

Having recently begun her guest stint in 'Portlandia,' Roseann Barr has landed herself another juicy guest role. Entertainment Weekly reports that the longtime 'Roseanne' star will appear in an upcoming episode of 'The Office's final season, guesting as a talent agent that helps a returning Andy Bernard (Ed Helms) realize his show business dreams.

It isn't known exactly when Roseanne's Carla Fern, will appear, though her scenes will be shot this week. Having returned from filming 'The Hangover Part III,' Ed Helms will return to the series in February 14 episode "Moving On." Also returning toward the show's May series finale will be Mindy Kaling and B.J. Novak, as well as Zach Woods.

Well, what say you? Do you think Roseanne Barr's appearance on 'The Office' will add much to the final episodes, or serve as distraction? How would you like to see the long-running NBC comedy wrap up?
