In September and October 2008 Fey was a guest on "SNL" to perform a series of parodies of Republican vice-presidential candidate Sarah Palin. On the 34th season premiere episode, aired September 13, 2008, Fey imitated Palin in a sketch, alongside Amy Poehler as Hillary Clinton. Their act included Clinton making fun of Palin about her "Tina Fey glasses". The sketch quickly became NBC.com's most-watched viral video ever. It had 5.7 million views by the following Wednesday. Fey acted in the role again on the October 4 show. She also acted as Palin on the October 18 show where she was joined by the real Sarah Palin. The October 18 show had the best ratings of any "SNL" show since 1994. The following year Fey won an Emmy in the category of Outstanding Guest Actress in a Comedy Series for her acting as Palin.
