Until this scene towards the last few minutes of the show...
That really cracked me up!
TV.Com Info: After learning that his old boss, the former regional manager, has died, Michael attempts to guide the Dunder Mifflin staff through their grief as he searches for the right way to honor a company man.
However, his staff don't really care. When asked to share their personal stories of losing a loved one, they took these "personal" stories from movie synopsis like Million Dollar Baby and The Lion King (which Michael failed to pick up on, until someone told his personal story following the story of Weekend at Bernie's!).
And the only one really grieving here is Michael. So much so that, upon seeing a dead bird by their office's door, he lost in and went insane. And so now we have this video of the bird funeral. Yes, that was what they were doing --- sending a dead bird to heaven!
Creed: "Humans can live for hours without their heads...
Dwight: That's chickens..
Creed: What did I say?
Michael: He died all alone...without his head to keep him company..."
This episode has "award" written all over it.
