Tom from Cambridge, England spotted this notice posted in “the tiniest little toilet in my college hall” — so tiny, he says, there’s “barely enough room to fit a dog in there if you tried.” (But a few raw steaks? Perhaps!)

I didn’t think i’d ever see a kitchen appliance more inappropriately anthropomorphized than this fridge, but I think this dishwasher note (from an anonymous submitter in England) dials the WTF-factor up to 11.

Most drivers could easily identify these duct-tape wrapped shapes as the universal sign for “Caution: Crazy Person Ahead,” but our submitter in Boston actually pulled over and parked in order to get a better look. Up close, “the signs were even crazier than we thought,” she reports. “Seriously, what happened to this guy?”

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.

I thought it was pretty crazy when Jessie sent in this sign from a thrift store in Wilmington, North Carolina a few months years back…

Then Ashley sent in this eerily similar note from a thrift store in Barnegat, New Jersey. “The first time I noticed it, there was only one note,” Ashley says. “Weeks later, when I came back to photograph it, they had added a second. Obviously, just the one note on the door wasn’t getting the point across. How do they know that the perp doesn’t only speaks French? That could be the reason for the recurring problem.”

And still, it continues!

Alice saw one at a thrift store in Tennessee…

Caity in New Orleans spotted another at Goodwill in Covington, Louisiana…

And now this, from Stephanie in Wichita, Kansas. Says Stephanie: “For years at our neighborhood DAV thrift store there’s been a dressing room that has smelled like pee. Turns out we weren’t imagining it!”

Seriously, what is it about thrift store fitting rooms?

Hannah saw this note on the window of a small toy store in downtown Sarasota, Florida. “They are really cool about it,” Hannah says,  ”but people still kiss the window.”

UPDATE: Jessica stopped by the same store recently (nearly two years later) and the sign is still up!
