Sunday is Sept. 11. In case you’ve been living under a rock, it’s the 10th anniversary of the World Trade Center terrorist attacks. Not surprisingly, there’s a lot of events this weekend to commemorate the tragedy. There’s also a lot of other stuff happening, but we’ll get to that in a bit.

There’s going to be a 9/11 Memorial Service at the North Charleston Performing Arts Center, the Citadel will host a couple of observance events, there’s Liberty Remembers 9-11: A Decade Later, and the 9-11-2011: An Interfaith Gathering for Peace will be held at the Sottile. There are also concerts by the CSO Spiritual Ensemble and Summerville Community Orchestra, the SCO solo, and the Charleston Men’s Chorus, Charleston Symphony Orchestra Chorus, and the College of Charleston and Citadel in Marion Square (which you can catch when you go to Second Sundays on King).

And now for the rest: There are so many possibilities for a good costume for Brought to You By the Letter C. Cookie monster. A candle. Or, technically, either gender’s reproductive organ, if you go by nicknames, but that might not be appropriate.

You won’t need a set of clubs for the Charleston Bar Golf Invitational. You will at the Edward Jones Charity Golf Tournament and the Gene Johnson Golf Tournament.

The Charleston Pro Tennis League plays its first game.

Since you’re going to be drinking beer and watching football anyway this weekend, raise some money for Operation R&R Charleston at the Citadel vs. Furman Tailgate and VIP Party. Songs and Salutes: An Evening with Patrick Davis and Friends will also benefit the organization.

Head up to Awendaw for the Francis Marion Dirt Dash.

After taking the summer off, Holy City Artists and Fleas is back with another marketplace at Eye Level Art.

There are two things happening this weekend that have a lot to do with Stella. One is A Streetcar Named Desire. The other is Michael Ian Black. One is kind of depressing. The other is a Tennessee Williams play. See how I made a joke there? Not that I actually think Michael Ian Black is depressing.

If you’re not a fan of MIB, Theatre 99 also has Comedy Combat and a Charleston Comedy Festival Stand Up Competition Preliminary Round. Other plays being performed this weekend include Boys’ Life, Chicago, and another round of Playfest.

The Sound of Charleston concerts continue.

The Patriotic Swing Dance Party features music from DJ Stephen Duane.

Charleston Ballet Theatre is holding auditions for their Broadway Dance Project and Palmetto City Youth Ballet.

All you need to know about the documentary The Kingdom of Survival is that Noam Chomsky is in it. I think from that you can get a pretty good idea of whether you’ll like it or not. And if you’re not, Movies at Mt. Pleasant Pier has the much more family-friendly Toy Story 3.

Treats for your pet and free chicken for you? The Canine Crawl sounds like a pretty good deal. Then take the pups to Dog Day Afternoon on Sunday.

Special Moments: Works from the Collection of Dr. Harold Rhodes opens at the City Gallery at Waterfront Park.

The Poetry Society of South Carolina hosts a reading by Sandra Beasley.

Enjoy the lovely weather we’ve been having by taking Coastal Expeditions’ Bulls Island Trip.

Dora the Explorer will make an appearance at the S.C. Aquarium on Saturday, in physical form.

The kids have been back to school for a few weeks now, but some may still need the boost that the Back to School Rally can provide.

Make Strides for Autism.

I’m not sure what it is about the Intergalactic Bead and Jewelry Show that makes it “intergalactic,” but I hope it’s because they’re going to play that Beastie Boys song on a nonstop loop.

I think all of us are guilty of liking a song by one of the Fall Fest 2011 bands at one time in our lives. For me: Papa Roach’s “Last Resort” when I was 12. Music fans may also enjoy the Meltdown Massacre 3 or the Red Light Circus Show Spectacular.

There are only so many opportunities left for Shaggin’ on the Cooper.

And the OPEN Arts Expo will give attendees the chance to learn about more than 35 local nonprofit art organizations and collectives. The City Paper’s going to have a booth, so drop by and say hello.
