Did you know that San Francisco’s sewer system collects everything flushed down the toilet, washed down the drain and all the rainwater that falls on the city? Now, would you like to tour those facilities on your bike? You're in luck. This Saturday, the SF Public Utilities Commission will pedal through the city's streets (not the actual sewers, ew) to explore "the wonderful world of wastewater." You'll get to visit San Francisco's treatment plants, pump stations, storm drains, outfalls, and "an innovative green infrastructure installation."

You will also learn about the interesting and bustling city beneath the city. It all starts on October 13 from 10:30-2 p.m. at the Southeast Wastewater Treatment Plant (750 Phelps Street (at Evans). RSVP to jwalsh@sfwater.org or visit facebook.com/sfwater for more details.

FILM: The "fascinating and even-handed documentary," Cleanflix, explores the world of the backroom entrepreneurs in Utah who clean-up racy Hollywood films to suit the puritanical Mormon community, resulting in "twists, turns and a sex scandal that surely would disqualify it from rental shelves around Salt Lake City." (7pm and 9p.m., Roxie Theater, 3117 16th Street)

MUSIC: L.A.'s Milk Carton Kids bring their "harmonies & minimalist instrumentation which are a clear reference to times passed, but with an eye intently on the future," to Cafe Du Nord tonight, along with fellow Angeleno, The Brendan Hines. (8 p.m., Cafe du Nord, 2174 Market Street)

HISTORY: FunCheapSF tells us about If the Walls Could Speak: Tales from the Mint, in which Old Mint docent Paul V. Turner gives his perspective as an "architectural historian and a man whose research has uncovered fascinating stories linked to the structure," one of the nation’s finest examples of the classical revival style. (7:30 p.m., Old Mint, 88 Fifth Street)

MUSIC: San Jose indie folk collective, The Mumlers, who are named after the "scandalized 19th century spirit photographer" William H. Mumler, will perform at Brick and Mortar tonight, along with guests He's My Brother She's My Sister and The Soft White Sixties. (9 p.m., Brick & Mortar Music Hall, 1710 Mission Street)

WALKING TOUR: City Guides presents its annual Ghost Walk at Palace Hotel, which explores tales of kings and presidents who have died here; gunshots that echoed through stately corridors, and romances that ended tragically. (6:30 p.m., Palace Hotel, 2 New Montgomery Street)

FILM: SF Film Society presents as part of the French Cinema Now festival Four Lovers, in which "[t]wo successful married couples looking for something new decide to share partners on an ongoing basis." Titillation and then tension ensue. (9:30 p.m., SF Film Society | New People Cinema, 1746 Post Street)

MUSIC: Midwestern-based, "retro-styled" rappers, The Cool Kids, who describe themselves as the black Beastie Boys, bring their fresh sound (sponsored by Mountain Dew) to Oakland's New Parish tonight, along with Go Corporate and Young Man. (8 p.m., The New Parish, 579 18th Street, Oakland)

FILM: Strangers Passing, a rare film from 1974 that falls "somewhere between gay porn and art film" and "combines explicit scenes and elements of tenderness (like holding hands and amorous courting)", is set in San Francisco and focuses on two men who meet through a personal ad in the Bay Area Reporter. (7:30 p.m., Yerba Buena Center for the Arts, 701 Mission Street)

TOUR: There are lots of various fun tours popping up all over the city these days, and Invented in San Francisco sounds like the most interesting one yet: "Explore the science behind the creations of some of SF's important imaginators, learn a bit about the neuroscience of creativity, and experiment with your own powers of perception." (5:30 to 8 p.m., Sydney Walton Square, Front and Jackson Streets)

In case you missed the Giants' World Series Trophy's brief stop at City Hall a couple of weeks ago, it will be back for a stint this Tuesday and Wednesday from 4 to 6 p.m.

The trophy will then head off in its wrapped 2011 Toyota Tundra CrewMax for the rest of its tour, stopping in Sacramento and making lots of other Bay Area and greater California stops.

Check the schedule here or look at the handy map.

The trophy will also hit the East Coast (notably the Giants' original home in New York), the Pacific Northwest, and the Southwest.

The trophy will make another stop in San Francisco on February 5 for the KNBR/Giants Fanfest at AT&T Park and will return in the spring for the big Giants Home Opener.

So, do you like books? Do you like people? Do you like people who like books?

Well, this is some depressing news on this oddly gloomy summer day. The Beastie Boys are canceling their upcoming tour, as well as postponing their new album release, because doctors discovered a cancerous tumor in Adam Yauch's left parotid (salivary) gland. Yauch explains his treatment and the band's future in the video above.

In a statement, Yauch also explained, "I just need to take a little time to get this in check, and then we'll release the record and play some shows. It's a pain in the neck (sorry had to say it) because i was really looking forward to playing these shows, but the doctors have made it clear that this is not the kind of thing that can be put aside to deal with later."

If you recall, the Beastie Boys were supposed to headline one of the days at the Outside Lands Festival in August.

FILM: In Being Michael Madsen, the titular star "turns the tables on notorious paparazzo, Billy Dant, by hiring a trio of documentary filmmakers to chronicle Dant's life, loves, and troubles." Crafty! The film also stars David Carradine, Daryl Hannah, and Virginia Madsen. Screens at The Roxie.

READING: Michael Layne Heath and William Taylor Jr. read in honor of Abraham Lincoln's birthday (and of being our first gay Republican president!) at Dog Eared Books.

* MUSIC: Put on your favorite black t-shit and whitest face powder. The queen has returned. Lead singer of Siouxsie & the Banshees and the Creatures, Siouxsie Sioux has influenced countless goth bands, punk outfits, girl groups, and trannies. Now, after a disastrous performance at the Warfield several years ago, she returns (this time to the Fillmore) for a two-night stay. Her "Mantaray & More Tour" opens with Rasputina.

CLUB: Before Trannyshack bids us adieu , check out the return of former Trannyshacker and current Scissor Sister Ana Matronic for "Ladies Choice" night. For those of you not in the know, the show starts a midnight at The Stud in SOMA.

The listed events were chosen by the editors of SFist and brought to you by the 2009 Toyota Corolla.

Because Valentine's Day is about necking, red roses, and Whitman's Samplers -- and not about making that special someone your creampie cutie for the night, you perverts -- the San Francisco Zoo's annual adult-only "Zoo Sex Tour" has changed its name to “Woo at the Zoo.” Why? No idea. But the zoo tells us:

Contrary to common belief, the animals will not “mate on cue” during the Zoo’s adults-only affair (21 years and older), but one will learn the many facets to the birds and the bees of the animal kingdom. Woo at the Zoo, formerly known as the Zoo’s Sex Tour, will entertain and educate guests through a multimedia presentation and up-close encounters with various creatures inside the Zoo’s Osher Great Hall. Led by former Zoo penguin keeper and animal-care professional, Jane Tollini, the 2008 dates for Woo at the Zoo are February 9, 13, Valentine’s Day (Feb. 14) and 15 at 6 p.m. and February 10 and 17 at noon for a special Sunday brunch presentation.

For more info, visit the zoo's site. And look at that: not one tiger attack reference. (Well, except for that one.)

N Judah Chronicles' Greg Dewar will not be pleased. And neither will the rest of you.

Just weeks after colliding with a 90-year-old woman on the corner of 9th Avenue and Irving Street, an inbound N Judah stuck a man at 31st Avenue, dragging him to 28th, killing him in the process. Overhead news helicopters, a Judah Street closure, and a police investigation followed suit. What's more, according to the Gate:

The incident was the second Muni accident of the night. About an hour earlier, a streetcar struck a car at 44th Avenue and Taraval Street, injuring several people who were transported to San Francisco General Hospital, a Muni spokeswoman said.

The number of people hurt and the extent of their injuries had not yet been determined, she said.

Charming.

The N Judah death, which occurred a little after 9 p.m last night, "stretched several blocks and...was very bloody." Of course, this raises many questions. For example, who was the victim? What was he doing at the time? How in the hell did the streetcar operator not know that they had just hit someone? Did any passengers know? He was dragged? Will the N Judah please stop its current campaign of perambulator terror?

We will update you with more info as it comes to us.

Update: The Municide (TM SFist tipster) victim has been identified as 40-year-old Mark Callaghan. And--get this--it seems that the San Francisco resident was attempting to board the N-Judah train at 31st Avenue "when the doors closed...Callaghan tripped and fell...then was dragged underneath the streetcar." Jesus.
