Tina Fey's Lasting Impression

Oprah filmed her guest-starring spot on a Saturday...the same day Tina was set to do her first impression of Alaska Governor Sarah Palin on Saturday Night Live. Between takes, Oprah says Tina sat at her computer and practiced the governor's distinctive accent and mannerisms. "I was little worried that I was going to start talking like that in the 30 Rock episode with you," Tina says. "That was the craziest day of my life. I feel like the only thing I didn't do that day was give birth."

When Oprah saw Governor Palin on television for the first time, she says she immediately thought of Tina. "The moment she came out, she'd not spoken 10 words, and I went, 'Oh my God. She's Tina Fey!'" Oprah says.

At first, Tina says she tried to argue her way out of portraying Governor Palin, but even her husband, composer Jeff Richmond, saw the similarities. "My husband was like, 'No, you have to admit it. You guys really do look alike,'" she says.

Tina says her 3-year-old daughter is particularly perplexed. "You can show her the New York Post with Sarah Palin, and she'll be like, 'That's Mommy,'" Tina says. "She's still confused about it."
