To me, this note is like that scene about 17 minutes into an episode of Law & Order, when the detectives run into an overly-talkative building manager and ask him he’s seen anything suspicious lately. Then, inevitably, the guy says something like, “Well, now that you mention it, ’bout two days ago, one of the residents tried to burn some old bloody clothes in that fireplace over dere. I guess the guy wasn’t too smaht, cause he didn’t figure out that fireplace ain’t real. You know, it’s just for show.”

Matt, a law student in Boston, surmises that this note posted in the school’s student lounge was written by non-native English speaker  — “the other possibility being that the stress of exams has eaten away at his ability to write coherently.” But what’s curious about this note isn’t the spelling and grammar so much as the the variety and specificity of immediate punishments that are promised within.

“For example,” asks Matt: “Will the food choke the perpetrator, or will Frank be the choker?  How will the burns be administered to the sleeper?” And so on. ”In any case,” he adds, “at least the various threatened deaths won’t be drawn out. (Also, to the best of my knowledge, there is no ‘video record’ of the refrigerator.)”

Brian in Boston spotted this aggressively service-y sign at a sandwich shop counter. Says Brian: “The girl working seemed to think that putting this up would be more effective than actually being polite and attentive.” (Further musings re: her state of mind were stymied by a “Whadda YOU lookin’ at??” glare.)

Upon moving into their new college house this fall, Danny and his roommates at Boston College received this delightfully punctuated welcome letter from their next door neighbor — delivered via U.S. Postal Service, no less.

I, for one, can’t wait ’til the Ben Affleck adaptation comes out. We’ll have a “late night beer party” to celebrate!

Jane in Boston says this note appeared on Tomio’s bedroom door, at cat’s-eye level. “Given that I’m pretty sure cats can’t read, it’s the ultimate passive-aggressive sentiment,” Jane says, “but a cat shitting on your bed is pretty passive aggressive, too. What a tangled web we weave.”

Meanwhile, a submitter in Cornwall, England spotted this note (again, at pet’s-eye level) on the front door of a house. “It was unclear what the dog had done, how the notewriter expected the dog to read this, or how ‘Diane’ was filming the dog,” our submitter says. “There was no sign of a camera.”

And yet, it’s this commandment —posted by a neighbor of Marissa in San Francisco — that tickles me the most.

UPDATE: A bonus note (via Anthonio in Seattle), from…Dirt.

Mothers truly skilled in the art of passive-aggression don’t need much to make their feelings known.

Just ask Rachel in Boston, who recently finished a three-semester master’s program a few months later than expected. “My mom was less than thrilled that my nine classmates finished on time while I struggled to edit my final paper,” Rachel says. “When I finally finished, we had a small graduation party, and she presented me with this gem of a cake.”

Meanwhile, writes our submitter in Madison, Wisconsin: “My mother has a bit of a ‘thing’ against any sort of carbonated beverage and constantly refers to diet soda as ‘the devil’s brew.’ I recently bought a little pack of the mini-cans of Diet Coke, and left one on the computer desk. After arriving home one evening, I found that my mother had kindly re-labeled one of my empty cans for me.”

In recognition of this particular skill, Amazon.com has apparently farmed out the writing of their suggested “PayPhrases” to stay-at-home Moms across the country…as Jessica in California noticed, on a double-take.
