New York's junior senator delighted and captivated congregants during Saturday services at The Hampton Synagogue in Westhampton. Clinton, whose step-grandfather was Jewish, addressed a number of topics, including terrorism and the Israeli-Palestinian conflict.

"The Senate has come through with a significant commitment of funds for the Israeli Defense Fund," she said to applause. "We will, I'm sure, be approving that in the coming weeks."

On Palestinian Prime Minister Abu Mazen: "He must demonstrate in deed what he has pledged to accomplish in word."

On the war against terrorism, she said: "Eventually we will be victorious because of what we stand for and who we are."

The Piano Man wants to set the record straight.

Talking to The Post as he surveyed the waters of Northwest Bay from his 36-foot boat, the Alexa, Billy Joel idly massaged his goatee and said, "My life is good, I have no complaints." But, he added. And there were quite a few buts.

Of the East Hampton car crash last year that fueled his notoriety, he said, "It was blown so far out of proportion, it was insane."

Photos of his Mercedes wrapped around a tree "made it look much worse than it was. I had no injuries. Nobody was hurt. No alcohol was involved."

On the subject of the media, he noted: "My girlfriend is not the maitre d' at Jeff and Eddy's."

His reference was to news accounts that Kate Lee, his new squeeze, works at a popular new Sag Harbor restaurant.

"She's the fishmonger in a fish store," he said.

"She wants to learn about local regional food. She's a potential chef. How better to learn about fish than in a shop that sells fish?"

"Dentist to the stars" Larry Rosenthal - who has brightened the smiles of Kathy Lee Gifford, Christy Brinkley, and Donald Trump - was rushed into surgery yesterday after crashing his moped during an afternoon spin in South Hampton, sources said.

A spokeswoman for Stony Brook Hospital said Rosenthal was in the intensive care unit, recovering from surgery last night.

Police and hospital officials would not give details of the dentist's accident. But sources said Rosenthal was riding his Vespa moped with his son when he was struck by a vehicle and seriously injured.

Sources said his son suffered a broken leg and was treated at South Hampton Hospital.
