Wild applause and cheers from the crowd who, for the price of admission, all got a copy of Fey’s new memoir, “Bossypants,” reports The Post’s Emily Yahr.

Fey announced this bit of Washington guest-casting in response to someone in the audience asking if she would toss out some spoilers for the rest of the show’s season.

The former Secretary of State long ago was established on the show as one of Jack Donaghy’s (Alec Baldwin) old flames.

Fey was interviewed by NPR’s Michel Martin, who lost all cred right off the bat when she announced she had a “girl crush” on Fey. And yet, Martin insisted on asking Fey serious questions -- like the “women in the workplace” question. Martin also launched a discussion about how “30 Rock” tackles race, gender, and social class while still being funny.

“30 Rock” tackles topics like race, gender, and social class?

Speaking of Sarah Palin – you knew that would come up – Fey called hypocrites all those who said she was “mean” to Palin but made no such comment when “SNL’s” Darrell Hammond impersonated Bill Clinton.

Fey said she was nervous that having Palin appear on “SNL” would create a “potentially very ugly moment” if the audience booed.

Which just goes to show you how everything is relative. One chick’s “potentially very ugly moment” -- another gal’s “fantastic live TV moment.”

Anyway, the “SNL” audience cheered that night. Presumably, that made Fey very happy.

When Martin finally stopped interviewing Fey, and the crowd got to ask the questions THEY wanted answered, they learned:

* Fey favors pirates over ninjas.

* If she could ask Charlie Sheen any question, Fey would ask: “Can I have $4 million?”

* “It’s hard to win a GLAAD Award when ‘Glee’ is on the air.”

* Fey’s advice for aspiring actors: “If you’re attractive, move to Hollywood.”

One attendee wondered if “30 Rock” could continue without Baldwin, who caused a brief Internet freak out last week when he said next season would be the show’s last, though he back-peddled later.

Fey said she could not picture the show without him, but if NBC asked her to continue, she would not want to let down the 200 people who depend on the show for their livelihood.
