The best and possibly only good thing about Sarah Palin's return to politics is that we once again get to gaze upon Tina Fey's impression of the part-time Governor. While Palin's recent endorsement of Donald Trump might have been scary for America's pundits and grammarians, it truly is great for comedy. On Saturday night (appropriately), Tina Fey returned to SNL to take on Palin, and the result is a sketch as hilarious, pointed and glistening as her sweater.
