New York, Oct 14 : Tina Fey is making waves with her impersonation of Republican vice-presidential nominee Sarah Palin on ''Saturday Night Live'', but the actress hopes it doesn''t last.
Fey, who has generated big laughs and big audiences for playing the Alaska governor, told TV Guide she can''t go on playing Palin forever.
"We''re gonna take it week by week. If she wins, I''m done. I can''t do that for four years. And by ''I''m done,'' I mean I''m leaving Earth," the New York Daily News quoted Fey, as telling the magazine.
