ANCHORAGE, Alaska -- Sarah Palin made a surprise appearance on "The Tonight Show with Conan O'Brien" on Friday -- and turned the tables on actor William Shatner.

In recent appearances on the late-night television show, Shatner has adopted a serious pose and recited some of Palin's less serious observations.

He was brought out again Friday to read passages from Palin's blockbuster "Going Rogue." The carefully selected passages included ones about rapper Kid Rock and stalking sheep.

Afterward, it was Palin's turn to read from Shatner's autobiography, "Up Till Now." The former Alaska governor's selections included one in which Shatner talks about visiting an African elephant "in my underwear."

After the readings, there appeared to be no hard feelings. The two left the stage arm-in-arm.
