Our submitter at a university in Canberra spotted this first note while getting his morning coffee. “Pat (a professor in the department) has been complaining for weeks that her coffee mug seems to disappear and reappear spontaneously. Her mood varies with its presence.”

Several days later, our submitter spotted this addendum, written by another professor sympathetic to Pat’s cause. “Since the mug hasn’t turned up in over a week, I’m pretty sure the culprit is too afraid to return the mug at this point.” (Could you blame him?)

Beth in London says this is only the most recent in a series of sad/hungry/angry household items created by one of her flatmates. “We’re all fairly disorganised,” she admits, “but one guy, possibly fearful of confrontation, prefers to avoid addressing any issues directly.”

Adds Beth: “A loo-roll holder with eyes is not a very appealing bathroom companion, by the way.”

Meanwhile, elsewhere in the United Kingdom, one of Emma’s flatmates decided to take a similarly cartoonish approach to their toilet troubles.

Writes our submitter in Madison, Wisconsin: “A coworker was cutting his fingernails into a community desk at work, so another coworker put on rubber gloves, collected the cuttings, and then put them into a sandwich bag with this note stapled on back in the drawer.”

The real kicker, though? As it turns out, there’s actually more than one nail-clipping culprit in the office, our submitter says, ”because several people took the note personally.”

Wha-wha-WHAT? I mean, one office weirdo — that’s practically a given. But an entire gang of clandestine communal-desk-drawer-nail-clipping coworkers?  That’s just messed up.

In this episode of targeted advertising gone awry, Jill in Nashville went the grocery store and bought a bag of chocolate chips (“to make cookies for work”) and one pint of Ben & Jerry’s (“just one, mind you!”)

If Jill sounds a little defensive, that’s probably because  — thanks to some disarmingly deadpan algorithms — she received this perky little coupon along with her receipt.

Meanwhile, a submitter in Ohio was about to reach for the Cherry Garcia — but stopped short when she spotted this “sign from above.”

“Every week there seems to be a new note in the office kitchen repeating the exact same thing,” says chenry in Canada. “Lately they’ve been threatening to throw away the dishes if you leave them in the sink, but they never do that either.”

“Now someone’s added his own sign taking the piss out of the rest.”

I don’t really want to know what “cigarette ashes” is supposed to mean in this context…

…but hey, look what I found on the Internets!
