Terry Gross recently interviewed Seth Meyers on NPR's "Fresh Air" show. He said some insightful things, for example:

Liberal people thought, "You did a great job. You took [Sarah Palin] down a peg. She didn't even know you were making fun of her." And conservative people were like, "She was great. She looked great in front of the camera. She showed she was a good sport." So people will see what they want to see, with pieces like that, if you do them right.
