Tina Fey hosted the Ad Council’s dinner the other night, where she made NBC jokes (“I really believe that if everyone in this room would watch NBC for one night … then that would be a 40 percent increaseâ€) and even did a brief Sarah Palin impression (“all of my ideas are in these glass things!,†meaning the teleprompter glass). It’s a little weird to see Tina do award-show-host one-liners, but once you get used to it it’s pretty funny.
