For all the partying they do, it's hard to believe the stars of MTV's "Jersey Shore" have time to compose a thought, let alone a book. The latest comes from Jenni Farley, whose "The Rules According to JWoww" (William Morrow, $20) went on sale Tuesday.

Like her reality-TV roommates Mike (the Situation) Sorrentino and Nicole (Snooki) Polizzi, Farley did get a literary assist from a writer. (Her wing woman was Sheryl Berk, who collaborated with Britney Spears on her autobiography.) But the dating advice is all JWoww, as Farley is best known.

She credits much of her worldly knowledge to the years she's spent on Long Island, where she moved from upstate New York in 2006 "ready to take over the scene," she writes. She spoke last week about some of the most salient of the 60 rules in the book.

Q What's a date killer?

Q What's the best pickup line you've ever heard?

A "Would you like a drink?" or "Hi, what's your name?"

Q Is it a good idea to get intimate on the first date?

A No, no, no. ... You don't want to seem easy, especially if you think it could be a long-term relationship.

Q When is it OK?

A At least when you get to know them, whether it's five or 10 dates, and the hooking up is kissing or something.

Q Is it ever OK to walk out on a first date?

A Only if they're disrespectful. ... I'd put money down for the check, and I'd be, like, "Have a good night." I always drive myself on the first date. So you're never obligated to stay.

Q How much booze is too much on a date?

A I would never drink more than two, or I would just sip on a glass of wine. ... You really want to take in what they're saying, because it is important. You don't want to wake up the next day and say, "Yuk, he said that, and I can't believe I laughed it off."
