BILL O'Reilly. Big man, big frame, big mouth. Big disclosure: I'm a fan. Sept. 23 comes his memoir "A Bold Fresh Piece of Humanity." Long back he sent my embargoed, not for sale, uncopyedited, bound manuscript with: "Here's something that might make you smile."

About the title he says: "In 1957, in the third grade of Saint Brigid's in Westbury Long Island, was a mouthy obstreperous kid by the name of William O'Reilly. Sister Mary told him, 'William, you are a bold fresh piece of humanity.' " The cover's a photo of wee Willy half a century ago.

His first page has the Pledge of Allegiance. His dedication is "To all 'Factor' viewers, listeners and readers. You guys keep me going." His mantra: "Living well is not the best revenge. Succeeding in your career and humiliating your critics is."

Considering his nightly prayer is to be in everyone's face on every medium other than milk cartons, why this personal book in which he digs back to family, neighborhood, church and school? "I wanted to tell how it all happened for me, for my beliefs. To tell the journey from a doltish working-class kid in Levittown to a champion bloviator on Fox-TV."

Great grandpa John was a saloon-keeper from Ireland. Grandpa John Jr., a New York City cop from Brooklyn. Bill Jr.'s dad and mom married in St. Patrick's. A former WWII naval officer, Senior had a reasonably "decent" job with an oil company. Anne was a stay-at-home mom. Theirs and everyone else's kids played in the streets because the yards were too small. Dinner? Usually "chewy meatloaf" or fish sticks.

Despite mostly NYC civil servant Democrat relatives, Kennedy vs. Nixon caused a split in their house. Senior disliked Nixon but considered Kennedy "a crook . . . his father sold booze during Prohibition."

Junior, who graduated Marist College with a degree in B.S. and quotes Teddy Roosevelt's "When they call the roll in the Senate, the senators do not know whether to answer 'present' or 'guilty,' " now says, "I vote for the person who I believe will do the least amount of damage to the country."

It's Broadway Books, and for $26 you can read the rest of the 256 pages yourself.
