Sarah Palin says she's on a crusade to bring the truth back to media.

(We didn't even know it had gone away.)

Speaking on the Jay Leno show last night she said it was time for Americans to be able to trust their media.

"I think the mainstream media is quite broken," she said.

"There needs to be a fairness and a balance there. That's why I joined Fox."

Apparently, according to Palin, the rest of the media (apart from Fox) is just publishing opinion masquerading as news.

Anyway, in betweeen promoting Fox, Palin did a good job of channeling Tina Fey channeling Sarah Palin.

Leno brought her back on as a guest comedy act and she did hit some zingers.

"I know these jokes like the front of my hand," she said in a reference to getting caught with what she called a "poor boy's tele-prompter."

She poked fun at L.A. saying that she was used to frozen faces from Alaska but in L.A. the frozen faces are usually botox.

But her best poke was reserved for Leno himself.

When asked about her future plans, she ran her hand along Leno's desk and said, "I hear once in a while this comes open.."

The woman's got a natural stage presence that's for sure.
