Mona in Los Angeles brings us this pair of notes from her high-rise Century City office building.  Says Mona, “Apparently my co-worker saw the panties at issue. My question is…who leaves their panties in the bathroom at work?  Who does that?”

My question: Why are we letting Paris and Britney off the hook? If they actually remember to wear them, shouldn’t we encourage keeping them on?

And then there’s this one, which brings up the old mad bomber-era debate about which gender leaves the bathrooms in worse shape.

Attention: corporate emergency in the Chicagoland area!

Meanwhile, in Seattle…

Adds our anonymous submitter, “All the glassware for all departments is washed by the poor lab slaves at least twice a day, and then promptly returned to the shelves. How much glassware are they using that they notice if a beaker or two went missing?”

Our anonymous submitter spotted this note on a resident’s door in an apartment complex in Portland, oregon. Oddly, she says, this resident lives alone.

Meanwhile, James’s roommate found in the laundry room of his Sacramento apartment complex.

So, our anonymous submitter had lived at her house in Austin, Texas for about two months when she went out of town for the weekend. For the two days while she was gone, she left her dog outside in the yard. Three weeks later, her landlord — who lives at a completely different address — received this note via U.S. mail…postmarked Cedar Rapids, Iowa.

a little creepy, right?

According to a 2006 Harris poll, office-workers say annoying ringtones are one of their biggest pet peeves — second only to office loud talkers. So I’m actually surprised we haven’t seen more notes like this one, which Flickr’s Heather Champ found taped to her (chirping) cell phone once upon a time.

What’s your pick for the most obnoxious ringtone award?

This note, from the science library of Washington & Lee University in Lexington, Virginia, has a bit of a backstory.

Explains our anonymous submitter: “Here, you can reserve a carrel for the entire school year, with two students to a carrel. Our honor system is such that people leave their books and belongings at their carrel basically all the time.” Our submitter caught sight of this little exchange and sneakily made a photocopy to share with us. (Oh, and FYI: “A&P,” our submitter says, refers to Anatomy and Physiology — a popular course that generally only seniors get into.)

“Random people seem to have a lot of fun vandalizing Portland’s many bus stops,” says Kathryn. “Several of the stops I use frequently have had their schedules removed, which is oh-so-helpful. The other day when I went to the stop in front of my office to go home, I noticed this little note. They even took the time to laminate it!”

Writes our anonymous submitter in Corte Madera, California: “We have a lot of passive-aggressive notes up around the office, and most of them are addressed to the entire office staff in common areas. You can imagine my surprise when after eating lunch and going out for a smoke break with some coworkers today, we came back to find a bit of passive-aggressiveness on our lunch table — not 15 minutes after we had left it. Grrrrr.”

More choice guilt-trips from this office — including yet another “your mother doesn’t work here” note, follow.

Craig from Nottingham, England snapped these at the pub where his cousin works. (Apologies for the blurriness — just pretend you’ve already knocked back a few pints.)

By the way, if you’d like to go meet Stephen and shake his hand, Craig says the name of the pub is The Flowing Spring, in Henley. Stephen seems like a kindred spirit to Desi’s New York dungeon master, no?

As this example from Winston-Salem, N.C. shows: hell hath no fury like a lactose-loving office worker.

The thief might be depending on the fridge’s contents as a source of food, but mercy? Don’t count on it.
