Tina Fey

Even when I was at 'SNL,' I didn't do impersonations. I always wanted to be the kind of person who could do them - I always thought they were the coolest thing on the show - but I didn't have any experience.

While it was occasionally done here or there, nobody else had a figurehead like Walt doing it. Jack Warner wasn't on TV. Walt was the boss, but he had a real public profile and he used it to his advantage. And he became a household face.
