Exhibit a) From a share house of would-be flip-cup players in Garfield Heights, Ohio (!!!)

Exhibit b) from an office in Dallas. Writes our anonymous submitter: “Everyone in the building knew who was trashing the bathroom, but no one ever confronted the guy directly about it. After about a year, this note went up.” (Not surprisingly, it didn’t work.) Finally, our submitter says, the building engineer went directly to the guy’s boss to, um, clarify the situation further.

And then there’s exhibit c) from a restaurant in Delaware.

Jen says this liquor store in Chicago’s Lincoln Square is completely plastered with notes like these, but — vexingly enough — the guy at the register was such a hawk she was only able to snap a few photos. Happily, I’d say Jen scored a hat trick for insolence with these three.

Our anonymous submitter says this display is just one of many microwave missives his coworker has created. “Someone tore it down and threw it on the floor once,” he says, “but she put it back up, laminated with heavy-duty tape.”

And of course, the art-imitating-life inspiration for this post: Pam Beesly.

The manager of a Florida preschool seems to have a kindred spirit at a Missouri strip club, where our anonymous submitter spotted this note taped to a dressing-room mirror.

Personally, I like the idea of an junior-high-elective-style employment program. (Dance? Restaurant management? Government? You decide!)

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.

“It seems too many people have made love to the office water cooler,” says Lizzy in New York. And some of them, it seems, are getting a little sloppy.

Lizzy says the “Office of Water” thing refers to the fact that “Our office is full of water. Like, the fridge doesn’t have anything but bottled water and Coke,” but I’m not quite buying it. I’d like to think this came from the EPA’s official Office of Water (Benjamin H. Grumbles, assistant administrator).

Another doozy of an apartment manager note from Oakland, California! Our anonymous submitter wasn’t able to save any of those 14 notices, so it’s unclear if any of them were anything like this one.
