Writes Brittney in California: “Apparently, my mom’s boyfriend was stuck with an insufficient amount of toilet paper, and being passive aggressive (because he really is) he decides to write a note about it and stick it on the mirror, rather than confront her.”

Mom’s response?

And, in the end….everybody loses!

“Our department head thought we should be be bringing in doughnuts more often,” says our anonymous submitter in Illinois. One of the department’s “severely underpaid” underlings, meanwhile, thought otherwise.

UPDATE: For those of you asking “But where’s the ridiculous clip art?!” I bring you this rather dashing toreador/sheriff (as spotted by Mel in the break room of her Ithaca, New York office).

While Mel doesn’t disagree with the sentiment behind the note, “It’s a bit off-putting to be presumed guilty of theft before the fact,” she says. “Also, there seems to be a degree of randomness to the number of exclamation points at the end of each line.” (And of course, that dandy of a sheriff.)

The long arm of Uncle Sam has extended all the way up to this roommate squabble in Peterborough, Ontario.

“The note on the right,” our submitter says, “is is written by a roommate who (as you can see) does not recognize the hypocrisy of calling someone out for being passive-aggressive in her own passive-aggressive note.”

I live in an apartment complex where most people know each other and are generally on good terms,” says Jin in California…or so he thought. As it turns out, there’s a pool of bold-underlined-all-caps-highlighted frustration simmering (oh-so-hilariously) just below the surface.

Hey, so do you remember hearing about how crazy cat ladies might be explained by the Toxoplasma parasite? (No? Then listen to this episode of Radiolab. It’s pretty awesome.) Well, Toxo may or may not explain these notes.

Exhibit a) Spotted by Shane at an office in Upland, California…

Exhibit b) From an apartment building in Austin, Texas…

A parable of the state of the “hot dot-com” workplace in 2009: The story goes, according to our anonymous submitter in California:

Some executive-level person decided to put a pinball machine into our break area. After several months, someone must have complained about the noise, because a note went up telling us it was not to be played. When some employees decided to play the machine at 7 AM (assuming nobody in the building was in), the note was replaced by a new (more specific) note.

After that, “the machine was unplugged and left to gather dust,” our submitter says…and to silently taunt all of the office’s embittered would-be pinball wizards. Until, one day…multiball!

Who needs a water cooler? Nothing fosters “community” like shared networked printers! Need proof?

First up, an anonymous submission from a cubicle farm in Rochester Hills, Michigan. (Not pictured, our submitter says: two additional copies of the same “Pomptly” note to the left and right of the original.)

And from Illinois…

From Omaha, Nebraska…

(And from Brooklyn…and just about everywhere else, from Glastonbury, Connecticut to Geneva, Switzerland.)

Meanwhile, Melissa from San Francisco was recently at the D.C. bureau of a news magazine for a press meeting, but being a devoted PAN-ista, she managed to sneak out of the conference room while the coast was clear to make sure she could capture this shot for us. (So please excuse the blurriness.)

Kellye from Huntsville, Alabama spotted these notes posted on boarded-up diner during last month’s G20 summit in Pittsburgh.

Explains Kellye: “The broken windows were caused by a few rowdy anarchists/drunk college kids from Oakland who apparently missed the mark in their defiance of the man. Since the vandals represented only a very small cross-section of protesters involved, other more local-friendly civil disobedients apparently saw fit to apologize for in their stead and offer their respectful patronage.”

Nathan in Norman, Oklahoma doesn’t know the writers of either of these notes, but when he saw this exchange on a fellow student’s drafting board in his architecture studio class, he knew it needed to be documented.
