Although I am looking forward to him being on the show, it won't be Ferrell. I am kind of dreading next season, because in my opinion, no one can play a crazy branch manager like Carell. He is really a perfect manager for The Office. I hope they don't try to replace Michael Scott with another character like Michael Scott. I am sure they will try to go the oppsosite way with it and try to incorporate someone else to be branch manager; someone that has conflicting ideas with the way Michael managed. Whether that will be a new character, or someone like Jim or Dwight, I don't know. I would like to see someone else come in to manage the branch. One person who comes to mind is Rashida Jones, who played Karen earlier in the series. Karen was also promoted to branch manager of another branch after the 3rd season. The writers have been putting Jim in awkward situations lately, and having Jim's ex-girlfriend come back would be funny. They could have someone to come in and just play a weird manager, like Zach Galifinakis or something. At this point, all we have is speculation as to who could play branch manager. In a side note, we haven't seen the last of Carell. Carell has said he would like to make guest appearances in The Office in the future.

I think that we need a completly new but just as wacky character. Someone who can look you dead in the eye with sunday go to meeting seriousness and tell you the biggest lie this side of hades, and make you believe it. Someone crazy enough to pretend to be a school teacher but end up teaching a class of kids to be rock stars in "School of Rock".

Jack is probably one of the few actors who has already been successful both on the show (in a 2009 episode), AND working with Will Ferrell (remember the 2008 Oscar presentation).

Who else is half as wacky and half as good a fit? Nobody, that's who.

Is there a more "Office-esque" pair than these two?

I think that once Michael Scott leaves, Dunder Mifflin should crumble. I'd like to see the entire company go under (as was strongly hinted in previous seasons). If "The Office" is insisting on doing another season, I think it should be a half-season that follows the lives of the employees after they've all been laid off. We would see them all trying to get different jobs, most of them finding complete unhappiness and realizing that they can't function as humans without... The Office. (See how it all comes full circle?)
Then, I think, the last episode should see all the employees coming back together to reminisce. (Clip show, anyone?)

Pee wee herman, I think pee wee should apply for the position...how awesome would that be! He's recently back on his game, his broadway appearance has been a huge sell-out successs. How rediculous would it be to have pee-wee as your boss! insane!
