Tina Fey reprised a tiny bit of her "Saturday Night Live" Sarah Palin impersonation last night during a presentation at the Ad Council Annual Dinner at the Waldorf Astoria Hotel in New York.
During her 7:40 minute routine, Fey made some jokes about the former McCain vice-presidential candidate's best-selling book, "Going Rogue," and then said (at around 2:40 in the video below), "Mrs. Palin and I continue to have so much in common. They recently made a porn movie... this is true... about Sarah Palin and then this same adult actress, Lisa Ann, played me in a porn parody of '30 Rock' ...Weirdly, of the three of us, Lisa Ann knows the most about foreign policy."
Fey saved her brief impersonation for the end of her time on stage, starting out in her own voice, "We'll begin with an issue that is," and then in her Palin voice "so critical to the future opportunity."
The audience laughed, and she said, "I'm gonna be doing that 'till I'm dead."
