The Olbermann Weekend

I like Keith Olbermann, but it's pretty much common knowledge that he's insane.

Which is what makes this SNL sketch -- with Ben Affleck doing a laugh-out-loud parody of Olbermann at his most unhinged -- so damn brilliant.

Look for a Countdown "Special Comment" tonight that reponds in kind: "Mr. Affleck... HOW DARE YOU, SIR!"
