Marcus in Leicester, U.K. found this stuck to the lid of the toilet by one of his housemates. “I’d understand if it was the seat,” he says, “but the lid?”

I’m with Marcus, here — I don’t think this is some kind of Dear Abby “does the toilet paper go over or under?” type issue. Is there anyone else who considers closing the toilet lid de rigueur?

Daniel in New York spotted this note (and the follow-ups) on the door of his SoHo office building’s restroom — “a nice single seater with a window.”

Adds Daniel: “I understand the sentiment — my sphincter locks up like a vise with any distraction. But I do hope that the large white area on the thoughtfully typed response will illicit a petition of like-minded others.”

Just in case gas prices aren’t hurting you enough lately, Tim from Madison, Wisconsin brings us this stomach-turning (yet impressively restrained) note from a petrol station somewhere en route to Green Bay.

Meanwhile, Tonya in Oakland passes along a photo taken by a traveler brave/desperate enough to actual enter a gas station restroom somewhere in Utah.

And finally, the kicker, from Jim in Columbia, S.C. —  who would’ve guessed that germaphobia and gas-station employment aren’t mutually exclusive?

An anonymous submitter in Portland, Maine is currently chafing under one of the most common irritants of communal living: a roommate “who has never once bought toilet paper.”

She and her other roommate tried some of the more subtle manuevers in the passive-aggressive playbook — up to and including the ol’ hide-and-carry — to no avail. (“When we run out, he uses our paper towels instead,” she says.) That is, until her roommate, who’d “had enough of plunging his shit,” decided to up the ante with this note.

Dealing with the rantings of your crazy boss or overzealous receptionist is one thing, but what do you do when your office’s resident passive-aggressive note-leaver doesn’t even work there? Casey in San Diego (a.k.a. RunBarbara) says that’s the situation she’s found herself in at her job.

The offender, Sandra, “has met me a total of twice, both times for less than a minute,” Casey says. Yet for some reason, when Sandra (the aunt of the owner) stops by the office once a week to water the plants and drop off supplies, “she leaves these strange notes EVERYWHERE — and she almost always directs questions about said notes to me,” Casey says. “I often have no idea she posts these notes until someone asks me about the odd directions in them.”

Below, a small sampling of Sandra’s delightfully bizarrre directives. (Just click on the photos to enlarge.)

I’d like to think this note was posted immediately following the “potluck”…

“I work for a pretty awesome non-profit, where people are amazingly laidback, accepting and non-OCD,” says our anonymous submitter in San Francisco — so this note came as something of a surprise.

Adds our submitter: “I have to admit, seeing the newspaper on top of the toilet tank the previous week had kinda gotten on my nerves too.”

What’s employee morale like inside Yahoo’s Sunnyvale headquarters, amid all the chatter about coming layoffs, the possible Microsoft takeover, and everything else? well, according to one anonymous Yahoo! employee, in the toilet would be one place to look.

Says our Yahoo! tipster: “First they took away our right to stand on the toilets. Then they took away our right to surf on the john. But now — they’ve gone too far.”

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!
