Plastination? Schmastnation. The "Body Worlds" thing at Franklin Institute — though sweet, if you're on that enzyme-snipping, polymer-popping tip (and I've snorted worse) — ain't nothing but messy compared to a dressy Halloween. I love H-Day so much, I'm blinder-ed until the 31st. (I'm also way too busy egging the windows of foie gras protesters.) Henri David — the jeweler behind Philly's famous-est Halloween bash at the Franklin Wyndham Plaza Hotel — ignores other nights too. While he'd love to egg PGN publisher Mark Segal (told you there was something fishy about the accounting behind his Elton benefit for the Dr. Magnus Hirschfeld Fund; but to "no-comment" your own reporters!), the mustachioed David is too busy thinking 'bout love. "It's 10 years since Paul and I [started as] a couple — on that day, yet," said David about his decade with partner Paul Struck. So congrats. While Struck is getting as secretive about costumes ("an homage to an art deco painter") as Henri, David revealed that one of his three costume changes will be psilocybin-laced. "It's definitely what an emcee at Disneyland'd wear on acid." Acid? Stefan Benarsky'll want in on that. The Philth publisher who finally got his fall Sports & College issue back from its printers and rumoredly, the hands of Canadian Mounties ("We don't know if it was a customs-censor issue or they just didn't print in time") is having a free sloppy, sexy Halloween at Bar Noir with the skronk-honking 722, the foul-mouthed Dirty Diamond and Needles Jones. And DJ Brendan O is spinning through the debut of his Soul Traveler Orchestra, featuring Instant Funk drummer "Biscuit" Rouse, singer Mary Wells and 10 other pieces weaving in 'n' out of breakless, beat-matched music. "Biscuit will beat-match whatever song I'm playing, the bass player will pick up the bassline, the vocalists will pick up the hook," says O. Oh! … WHOWHATWHERE: "What am I wearing? Myself? said Brini Maxwell about her self-designed Rhoda-esque purple 'n' white wool tweed outfit worn while hawking her Guide to Gracious Living to the Book and the Cook's Caffé Society crowd at DiBruno Bros. Chestnut Street last week. She thought the Mignucci boys "chivalrous." Less conspicuous — maybe not even there — was director M. Night Shyamalan who threw a wrap party for Lady in the Water Saturday at Patou. Though Paul Giamatti hung and chatted the night away with Lady's 249 other players, spies never spied Night. And where has Comcast network graphic dude Eric Weiss been? On tour with John Legend, directing documentary bits on his Philly bud for use on a due-December DVD. "We've been in Australia with Black Eyed Peas, with Kanye West doing a BBC show live from Abbey Road Studios and hung in Melbourne with Garbage's Butch Vig." After much drinking Weiss shot a live Garbage vid. "It was like living in rock-star camp," says Weiss, currently editing like mad. And stop or my mom will shoot: Sly Stallone's scouts are already snapping photos — the Alhambra arena, Joe Hand Boxing Gym, Ralph's on Ninth — for Rocky Balboa. Arg. … No sooner than we was ready to celebrate the double comeback of David Reilly (the ex-God Lives Underwater guy) signing a long-term solo deal with Chris Schwartz's new RuffNation/Universal label deal, then Reilly dies — not from some previously rumored, long-done-with-addiction bullshit, but a bleeding ulcer. FUCK! Sad? We have no words. … Yes, Jay-Z raided Philly for his DefJamLeft label, taking The Roots' Game Theory for February release. But might Hova poach Jaguar Wright from Artemis? … Think Brad Pitt yelling in Troy, "Take it, it's yours": The Painted Bride Quarterly lit rag — a local staple since 1973 until it moved to Rutgers Camden campus (fuckers!) in 2000 — returns to Philly at Drexel U. Charge! … It's sonorous, sweet and way-askew on the rhythm stick: Pattern Is Movement's new CD, Stowaway, gets its release party at Manhattan Room, Oct. 28. … Laid: The original 30-year-old virgin — Ian Morrison, or his drag-comic personae Brittany Lynn — finally gave it up… to a 21-year-old. "I sooooo wanted to wear white at me wedding," said Lynn. "My gay friends are relieved. They worried I was a closeted straight boy." … Fox's Good Day done did the right thing — hooking up longtime contrib Michele Malin Seidman with her own Friday lifestyle segment Seidman Sez. Get-'er-done. … Longhair hippie freak Roni Koresh and his shorn-haired bro Alon's family-named dance company will celebrate The Dancer's Fund (to secure their nine-members' salaries for 2005-06 season) with their annual Annenberg Center program Oct. 27 and 28. Be there. Or hit alon@koreshdance.org. Give bags of money. … Jack-o'-lantern b-days are bestest — give it for restau-real-estate mogul Brett Brassler, fashionista Jaclyn Samschick, Beretta 76 howler Camille Escobedo, Bebek keys-stroker Nick Michalopoulos (who play Tin Angel Oct. 29, face sheet-caked 'n' all) and to Marty Feldman. Not the comic — the trainer and dad of boxer-turned-Hollywood-bound Damon. Hey, Damon finally explained his reason for leaving Philly. "I'm just sick of the BS. The commissions are fucking boxing up — people who don't know anything." Wait till he hits L.A.!
