When Sheena in Austin spotted this note on her neighbor’s front door, she couldn’t help but wonder: “If your doormat has sentimental value, maybe it should be hanging on your wall instead of sitting on the ground?”

Writes an anonymous submitter in Houston: “A neighbor in my building put up an Obama yard sign on the door of her apartment around the time of the Texas primary. When it disappeared, I assumed she took it down herself.”

Then up went this note — a cheerful bit of propaganda that oh-so-subtly disproves all those ugly stereotypes about “self-righteous Obama supporters” with a colorful blaze of moralistic tsk-tsking and First-Amendment flag-waving. (Woo! Obama ’08!)

Sure, it’d be easier and quicker to just clean it up. But the modern passive-aggressive (like Katey in Berkeley’s ex-roommate) can’t pass up the opportunity to make a point.

A common variation on the Van der Rohe approach, as documented below by Sam in Dallas, is the so-called “Reverse Magritte.”

Meanwhile, post-modern passive-aggressives (like this New York office-worker below) can’t resist throwing some irony into the mix, intentional or not.

More recently, passive-aggressives have begun to show the influence of the burgeoning neo-pop movement. Our anonymous submitter in Houston, for example, designed the original stamp below for use in his work. “I am an engineer and we have to mark up technical drawings for manufacture,” he explains, in his artist’s statement. “It gets used at least twice a day.”

The bleeding-edge of passive-aggressive note-writing, however, lies on the west coast, where Rebecca in San Francisco says that in the past, “We’ve had an ongoing series of notes left in the office kitchen — usually of the ‘your mother doesn’t work here’ or ‘there is no such thing as the coffee fairy’ variety.” The Koons-inspired piece currently on display in the office breakroom, however, makes its point with no words at all.

While paying his old office a weekend visit, Jimsu from Katy, Texas didn’t catch the original note (or, perhaps, conversation) that precipitated this huffy screed from the mailman…

…but he did spot the follow-up from the office smartass.

Alexa in Texas works in a graduate lab of five students. One Friday, she says, “our advisor came in around 9:30 a.m. looking for us. No dice: except for one poor guy, we were all out.” When the hard-working crew finally rolled in around 1:30 (or, um, 3 p.m.), they were greeted by this inspirational slogan pinned to the door.

Sure, those luxury condos going up all over downtown Austin might look swanky, but our anonymous Austin submitter says her building offers plenty of exciting local color you won’t find in those glass-and-steel towers.

Perks include: 1) the building’s property manager, a character known for his impassioned screeds about everything from trash cans to expired vehicle registrations, and 2) a recurring sewage back-up that flows into the downstairs bathrooms of all the units. Rock ‘n’ roll, dude!

“The roto-rooter has said repeatedly that the backup is caused by roots growing into the sewer system,” our submitter says, but that explanation didn’t seem to satisfy her tireless PM. Now he’s offering tenants flexible lease arrangements, too!

While you were drunk-texting your latest Eugene Mirman sighting to all your pals, more industrious folk like Bryan from Minneapolis,  Betsy from L.A., and Adele from Montreal were documenting the comedic gold being served up by Austin bartenders.

Before I pass out, I bring you a few of my favorite more-aggressive-than-passive notes from the music clubs of Austin.

First, from Scoot Inn…

More bouncer sass from (I think) Beerland…

And lastly, from Emo’s…
