The proper care of outdoor cats has become one of those issues — like tipping, or whether the toilet paper roll should hang over or under — that will no doubt incite flame wars until the end of time. That said, Lindsay in Oregon was still a bit surprised when this note appeared on her apartment building’s bulletin board, given that “FOUND” posters referencing the same collar-less cat had been posted on said bulletin board for weeks on end.

After experiencing similar problems with the neighbors (despite the fact that his cat already wears tags with his owner’s phone number on them) Elisa’s friend in Seattle had another tag made in hopes of preventing future trips to “kitty jail” — or at least to piss of the neighbors taking his cat there.

Our submitter, Rob in Cleveland, says he found this note on his computer screen upon returning to his desk after lunch one day. “I honestly don’t bring my toenail clippers to work,” Rob says. “They were just hurting inside my pocket so I put them on my desk and forgot about them, and this is what I get.”

At first glance, I thought the note must have been sarcastic — surely, no one would actually borrow another’s toenail clippers, right? — so I asked Rob for some clarification.

As it turns out, Rob is pretty sure the note was no joke. “The guy who wrote it is one of the grossest people at work,” he explains. And as for why he had toenail clippers in his pocket to begin with? Says Rob: “I cut my nails in my car on the way to work.”

Of course. Well, I’m glad we cleared that one up.

Shawn in Pennsylvania found this oh-so-subtly guilt-trippy thank you note tucked inside his Sunday paper. (“Apparently our paper delivery person is hoping for bigger and better tips in 2011,” he says.)

Writes Justin in Salem, Massachusetts: “It was the middle of the recent blizzard and we had gone for a drive in the worst of the weather (because that’s what you do for fun when you drive a Jeep) and decided to stop for a cup of coffee at Dunkin’ Donuts” (because that’s what you do for fun if you’re a New Englander).

Upon arrival, Justin and his companion were greeted with this heartfelt note of congratulations from the Dunkin’ Donuts snowstorm staff (Rick).

Part 2 in our “How to be the worst neighbor ever” series comes to us courtesy of Chris in Fort Worth, Texas.

When he first saw the note go up in his apartment complex, says Chris, “I thought it was pretty funny, but it wasn’t until the thief wrote a response that I had to take a picture.”

Stuffing your neighbor’s mailbox with a bag of dog poo/a dead rodent/a hundred boxes of orange tic-tacs? So amateur. If you really want to drive someone crazy, try repeatedly scratching out her name and writing “VACANT” over it instead. Apparently, it works like a charm.

Our submitter, a college student in Wisconsin, passes along this “debackle” of an e-mail a girl in her art history class recently sent to all the other students in the class — and, in a particularly gutsy/idiotic move — to the professor, too.

Adds our submitter: “The funny thing is that the class is actually very enjoyable, the instructor has never changed a test date/format, and the lectures are always well organized and engaging. Judging from all the spelling errors, she might want to drop art history and pick up an English class instead.”

Shortly after moving in to her new place in Minneapolis, Emily was greeted by this example of that famous “Minnesota Nice“ on a neighbor’s door.
