Live From Jezebel, It's Saturday Night!Once again, Sarah Palin has managed to upstage John McCain: about 2 hours ago, John McCain's appearance on Saturday Night Live tonight was the presidential pop-culture buzz of the moment, but now that Palin Prank Mania has been unleashed upon the internet, the Republican nominee's appearance just don't seem as interesting anymore. Still, the combo of host Ben Affleck, a hardcore supporter of the Democratic Party, and Senator McCain should provide us with some interesting scenes, to say the least. Will McCain be funny? Will the audience be respectful? Will there be an appearance by the great Tina Fey? We'll just have to watch to find out.
