Yup, you read that headline correctly: Sarah Palin does a Tina Fey impression in this fake trailer for "31 Rock," starring Palin as a Liz Lemon-like writer, Lindsey Graham as Kenneth the page, and John McCain as Jack Donaghy (plus, the guy who actually played Dot Com as Dot Com!). Though the video is apparently from The Independent Journal, it actually seems to serve as a trailer for Palin's new book Sweet Freedom: A Devotional (according to Amazon, reviews include "Just received a copy of [Sarah Palin's] new book—a great read! Sarah is a terrific person."— Donald J. Trump). Really, it's only fair that she play Tina Fey after the comedian impersonated her yet again on SNL last weekend.
