Unsurprisingly, Emily in D.C. says it took less than 24 hours for one her neighbors to call bullshit on the building management’s “exciting news.”

Meanwhile, this building in Columbus, Ohio — which submitter Andrew says is “really nice and fancy-looking” — appears to take the mullet approach to policing its public spaces. (Business in the front, party in the back!)

Adds Andrew: “I 100% believe that this note is legit. I work exactly one block away from where the sign was posted, and a few days ago, I went outside only to find my self interrupting someone who was pissing on our dumpster. We have caught people in the act of shitting in our parking lot, and have also received many “anonymous fecal gifts.”

Tim lives in Northwest D.C., “at the front of the gentrification wave” flowing east from Dupont Circle. “We have (only) one rundown/uninhabited house on the block,” Tim says, “and this morning one of the other neighbors decided to mow the front lawn to tidy it’s appearance a bit.” While taking out the trash later that evening, Tim noticed that his neighbor’s good deed had been rewarded by this neighborly thank-you note.

(As far as the smell goes…perhaps some people were under the same mistaken impression as those near this West Hollywood residence?)

Chad and Cassie might want to be careful what they wish for…lest someone be tempted to “return” something they didn’t actually borrow first.

Edie in Bellevue, Washington wasn’t too happy with the neighbor’s cat using her lawn as its personal toilet, so she finally asked the cat’s owner if she’d please clean it up. “She did,” Edie says, “but only after explaining that the cat poops on everyone’s lawn and no one else minds.” (After asking around the neighborhood, Edie found this to be only half-true.)

Little did they know that cat’s crap was practically worth its weight in friggin’ GOLD!!! One can only imagine the reactions of Edie and her similarly ungrateful neighbors when they finished reading the photocopied letter taped to their front doors. (First place? For three years running?? What fools we’ve all been!!!)

What’s frightening, of course, is that these things needed to be stated in the first place.

When Sal spotted this notice at an athletic clothing store in San Diego, he says that while he couldn’t quite picture how a tissue would get the job done in this situation — not to mention how this policy came to be —  “I figured it was best not to ask questions.”

Meanwhile, when I first read this sign — from a club in Vancouver — my first thought was, “Well, that seems like a reasonable enough request.” Our submitter, Cherisse, begs to differ. “Sadly, there is no bathroom backstage,” she explains, ” wnd when a girl’s gotta go, sometimes the other end of the club is a long ways a way.” She adds: “If it wasn’t for the used paper towels being left outside, no one ever would have known.”

So… like Sal, I’m gonna say it’s probably best not to ask too many questions about this one.

This seems like a reasonable enough request to ask of your housemates…except for the fact that, as Jason explains, “Our water is full of assorted minerals (and who knows what else), and drips from the ceiling above the bathtub all day.”

So those yellow stains in the tub? Yeah, not urine. Just evidence of a bathtub in need of some serious scrubbing. (And those pink stains on the water cooler? Probably not lipstick.)

But if your shower smells like piss…well, it’s gonna be hard to blame that on hard water.

Though your attention might have drifted ever so briefly, I’d like to reassure you that the ongoing debate over which restrooms (men’s or women’s) are the foulest continues to rage on — and yes, it’s as nauseating as ever!

I literally received these two submissions — the first from an EMT school in Massachusetts, the second from a non-profit in D.C. — within minutes of each other. Mere coincidence? Or a cosmic clue from the Internet gods that it was time for a showdown between “Angulated Rectum Guy” and “The Queen of Diahrriah?” Okay, that was a gimme. The real question: who would you rather share a loo with?

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.
