They're horny as hell, and they're not gonna take it anymore! Fed up with the continued efforts to turn New York into the new Salt Lake City, the Porno Liberation Front has decided that it's time to fight back. A self-described "guerrilla group of artists, writers, and free-range intellectuals," the PLF is dedicated to preserving our freedoms and our mental health by maintaining an open and public discourse about sex?which sometimes involves the public display of explicit materials. Their first event takes place this Fri., Jan. 31, where they will be screening Ship of Shame: The Story of DE 733, the notorious 1942 Dept. of Defense VD film. Ship of Shame will be introduced by Ken Mondschein, author of the forthcoming Feral House book A History of Single Life. Collective Unconscious, 145 Ludlow St. (betw. Stanton & Rivington Sts.), 212-254-5277; 18+ only, 8 p.m., $8. Visit http://www. corporatemofo.com/pornlibfront/index. htm for more information.

One would be surprised at the number of cool people who've not seen the requisite cult classics now passe to sophisticated, former high-school art fags such as yourself. (And then doubly shocked at the amount of admiration one will inspire among one's acquaintances after the introduction, not to mention the extent of one's own enjoyment at another viewing.) Hence, in the spirit of Film Forum's recent Beyond the Valley of the Dolls screening ("This is my happening, and it freaks me out!"), the best little revival house with the most insufferable patrons offers a Peter Sellers two-week retrospective, beginning Fri., Jan. 31, including The Ladykillers, What's New, Pussycat? and Dr. Strangelove. (Although the latter may be a tad too close to home for many Americans today, the only threat bigger than Bush's brain being Saddam Hussein, rightly referred to below the Mason-Dixon line as "Sodamn Insane!") 209 W. Houston St. (betw. 6th Ave. & Varick St.), 212-727-8110; call for sched., $9.75.

As a subspecies of photography, the crime photo is a perennial favorite, for in all their grisly glory, tabloid-news, crime-scene and police pictures are fascinating in a way conventional art photography seldom is?these often-anonymous pictures are the workaday records of lives misspent. The master of the form was Weegee, who made a good living shooting the shadier side of life, thanks to keen attention to the details of his craft?such details as putting the fedora back on a recently gatted body because editors liked to see a corpse with a hat on. Most crime photos were not so well-executed, although a lot of the ones on display in "Shots in the Dark: True Crime Pictures" are the cream of the often gruesome crop. Stephen Shanes', Alex Tehrani's and, yes, Weegee's works, among others, are gory, frequently disturbing or heartbreaking, but always riveting, and can be seen through March 15 at the Chelsea Art Museum, 556 W. 22nd St. (betw. 10th & 11th Aves.), 212-255-0719; Weds.-Sun. 12-6, $5.

When saxophonist Neal Sugarman takes the stage with the Sugarman 3, it's hard to believe that the blast of ass-friendly funk isn't the work of a much larger group. The big funk sound from his combo doesn't so much resurrect old-school funk as reclaim it for themselves, and he knows how to power up the chords so that the whole house finds the kinetic part of its booty. Sugarman probably wasn't born when James Brown was in his prime, but he's a worthy disciple of the gospel of dirty funk. If the headlining Antibalas Afrobeat Orchestra has even half the sound Sugarman does?and many of their musicians played on Sugarman's most recent album?then this show must not be missed. Bring someone to dance with on Sat., Feb. 1, at Bowery Ballroom, 6 Delancey St. (betw. Bowery & Chrystie St.), 212-533-2111; 9 p.m., $12.

Prepare to spend as much of this week as possible in CUNY's Art Gallery of the Graduate Center. Its current exhibition, "Antoni Gaudi: A Multi-faceted View, The Work of Gaudi in Contemporary Catalan Photography," is the perfect opportunity to familiarize yourself with the architect's colorful, whimsical forms and swooping parabolic curves?especially with talk of erecting a never-built 1908 Gaudi skyscraper (originally designed as a hotel) downtown on the WTC site. His designs might seem a little bright and a tad foreign this far outside of Barcelona. But we're sure that, by the time the exhibit closes on Feb. 7, even the most austere minimalists will value the hope and grace inherent in Casa Milá or the Sagrada Familia cathedral. It should prove a (ahem) revitalizing experience. 365 5th Ave. (34th St.), 212-817-8215; Tues.-Sat. 12-6, free.

Last time we were rolling we met this crazy guy who did amazing puppet shows. We didn't realize it then (we thought he was just spontaneously entertaining our cuddle puddle), but he has shows from time to time that really kick ass. Besides, we're tired of our usual Saturday night outings: packed bars, creepy clubs and boring flicks. This Sat., Feb. 1, we're going to experience eclectic excitement and hearty laughter, and we also might get laid by a clown: we'll be at the Bowery Poetry Club to see "Failure," a show of tap dancing, mimes, ventriloquists and even a punk rock accordionist. Did we mention our E entertainer Nick Jones will be there showing his slideshow? 308 Bowery (Bleecker St.), 212-614-0505; 8 p.m., $7.

Back in college we'd always finish our night bartending with the soundtrack to Crooklyn. We couldn't play "Pusherman" or "ABC" loud enough. Shelton Jackson Lee, better known as Spike Lee, has done a lot since his mid-90s bittersweet comedy, which is probably why he's being honored for Black History Month. Beginning Sat., Feb. 1, and running every Tues.-Sun. through the end of the February, "A Spotlight on Spike Lee" series, featuring Lee's student film Joe's Bed-Stuy Barbershop: We Cut Heads and his made-for-television documentary, A Huey P. Newton Story (which won a Peabody), screens at the Museum of Television & Radio, 25 W. 52nd St. (betw. 5th & 6th Aves.), 212-621-6800; 12:15, $10, screenings free w/mus. adm.
