Tina Fey reprised her impersonation of Sarah Palin for Inside The Actor’s Studio last week (video above). This included “Palin” discussing guns saying, “if everybody had guns, there would be fewer guns in the stores.”
Tina Fey can also be seen impersonating Sarah Palin here, here, here, here, and links to her older appearances are here.
