Sarah Palin, whom you might have heard of, said recently that she could defeat Barack Obama in the 2012 presidential race. Is the White House intimidated? Not... really, if Joe Biden's reaction on MSNBC is any indication.

You know how, every now and then, a player on Saturday Night Live will break character and laugh in the middle of a sketch? Comedians call this "corpsing." You know how sometimes that can make an okay sketch into a hysterically funny one? That's kind of what this is like.
