As if having Will Ferrell show up for the tail end of this season wasn't good enough, the season finale of The Office will have another fantastic guest star. EW reports Jim Carrey will appear on this season's last episode which will air May 19th. Keep in mind that since Steve Carell is leaving the show before the last episode there's little chance that we'll see Bruce Almighty and Evan Almighty on screen together, but maybe they'll surprise us. Carrey joins the ranks of Ricky Gervais, Will Arnett, James Spader, Ray Romano and Catherine Tate as one of the many people interviewing to take Michael Scott's job at Dunder-Mifflin. The episode is one of those hour-long installments, so there's plenty of time for more guest stars. I just hope there's still some surprises in store for us. Either way, Carrey should make for a great appearance to finish the season.
