In "31 Rock," Palin plays a harried television writer who moves to New York City to work on a variety show.
"She's struggling to have it all," the narrator says. "While also putting the smack-down on political correctness."
"30 Rock" actor Kevin Brown, who reprises his role in the spoof, carries a copy of Palin's book "Sweet Freedom: A Devotional," which he calls "a great reminder of the pressures of PC culture."
"The only PC I need is right here," Palin says, pointing to her laptop.
The video was posted following Fey's appearance on "Saturday Night Live" over the weekend, where she reprised her role as Sarah Palin.
