Will Ferrell is becoming the go-to guy for momentous NBC exits.
Ferrell, who sang "Freebird" to take the sting out of Conan O'Brien's "Tonight Show" exit, will join "The Office" for four episodes to ease Michael Scott's transition from Dunder Mifflin.
Ferrell wil play a branch manager who arrives from the home office and turns out to be as inappropriate as Michael.

"We found Steve Carell when he was nothing but a movie star and we turned him into a television star,” said executive producer Paul Lieberstein. “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.”
The "Anchorman" co-stars -- who once vied for the same spot on "Saturday Night Live," which Ferrell got -- will appear together in three of Carell's last four episodes, and Ferrell will remain for one episode after Carell leaves.
Maybe Carell's departure will put Ferrell in a singing mood: In addition to the O'Brien sing-off, he also led a rendition of "Good Night Saigon" that served as an "SNL" goodbye serenade to Darrell Hammond.
