Appparently it's a total rip on Republicans and Faux News tonight. I missed it, as I'm currently watching The Pentagon Papers on that other Fox Network, FX, but if you're in a more Westerly time zone, don't miss it.
Don't want to spoil it, but as a teaser apparently the Fox News Crawler had such things as "92% of Democrats are gay."
