Tiny Fey has won laughs playing Sarah Palin, and now America will see if Palin can win votes by appearing alongside her.
The vice-presidential candidate, whose public image has been shaped - and not necessarily for the better - by the Emmy-winning comedienne's portrayal of her on Saturday Night Live, is scheduled to appear on the comedy programme this weekend.
According to the Associated Press, the Alaska governor will make a guest appearance on the show hosted by actor Josh Brolin, star of Oliver Stone's new biopic W.
The long-running NBC staple is a favoured stop for presidential candidates – John McCain once hosted it and Barack Obama made a brief cameo during the campaign.
Thanks to Fey's send-up of Palin, the show has seen a revival in relevance, and recently began running a Thursday evening special edition of its "Weekend Update" news satire. Fey in some cases has used Palin's words verbatim, notably from a televised interview with newswoman Katie Couric, to devastating effect, drawing the public's attention Palin's apparent lack of command of national and international affairs.
McCain spokeswoman Jill Hazelbaker confirmed to the Associated Press that Palin will be on the show, but offered no details of her performance.
Palin has said she is a fan of Fey, the show's first female lead writer, and has quipped that she is happy to lend the show new material.
