Smackdown...

If you're unfortunate enough to know who Keith Olbermann is, then you know that what he needs more than anything is a good smackdown.  That's exactly what has happened here, delivered by none other than Bristol Palin, of all people.  Money quote:

I have never claimed to be perfect. If that makes me the "worst person in the world" to Mr. Olbermann, then I must apologize for not being absolutely faultless like he undoubtedly must be.

Definitely read the whole (short) thing.
