Appearing on CBS' "Late Show with David Letterman" scheduled to air Friday, Fey shared her formula for having spoofed the Alaska governor in recent "Saturday Night Live" sketches.
"It's a little bit `Fargo,' it's a little bit Reese Witherspoon in `Election,"' said Fey, adding she also borrowed the Midwestern accent of her friend Paula's grandma, "a sweet, sweet old lady from Joliet, Ill. She would always say, `Ohhhh, this and that and stuff like that!"' Fey, the star of the NBC comedy "30 Rock," was formerly a writer and cast member at "SNL," where she has made a splash with guest appearances this fall making sport of her resemblance to the Republican vice presidential hopeful.
She explained to Letterman other ways she captures Palin's distinctive speaking style: dropping g's and loading sentences with r's."
"She's digging those r's," Fey said. "I think she thinks there's oil in those r's - she is digging deep!"
As spoof made way for reality, Gov. Palin was scheduled to appear on "SNL" Saturday. There was no word on whether Fey would be on hand.
