As witnessed by tonight's already-spoiled cameo appearance form Ricky Gervais, The Office is pulling out all the stops for Steve Carell's final season. Nothing says farewell like some high-powered stunt casting!

The latest? Will Ferrell, who will guest star on the NBC series in the spring for up to four episodes. Producers say that the Anchorman star will play a branch manager from the Dunder Mifflin home office, and serve as a "bridge" between Carell's departure and the eighth season of the series. According to Deadline, Ferrell will appear in four episodes, at least one of which will come after Carell leaves in the early spring.

"We found Steve Carell when he was nothing but a movie star and we turned him into a television star,” said The Office exec producer Paul Lieberstein in what you can only assume was his Toby Flenderson deadpan. “We are proud to continue The Office’s tradition of discovering famous talent, and we hope that once America gets a good look at Will, they’ll see what we see: tremendous raw sexuality.” Har.
