If, like me, you enjoy watching the childish taunting and catfighthissyfits of cable network talking heads, then you, like me, will enjoy this video clip of MSNBC’s Keith Olbermann in an apparently on-air dressing down of Fox News pundit Bill O’Reilly.

It’s a train wreck, yes, but it’s a HILARIOUS train wreck.

(Quicktime required, but OH SO WORTH IT)
