Writes our anonymous submitter from Michigan: “Yesterday, one of our salespeople was observed playing Angry Birds on her phone – with her headphones on to hear the game sounds. Today, this sign showed up  in the sales office.”

William in Sydney spotted this note on the notice board of an apartment block he was visiting. If you’re going to tackle a DIY project, I reckon that Saturday morning is as good a time as any, no?

Confidential to the notewriter: As someone who also a) lives in an apartment complex and b) works the night shift at a hospital, I’m surprised you haven’t figured out by now that the world doesn’t revolve around you and your schedule. The graveyard shift is already taking years off your life. How about you do everyone a favor and use some of that sweet shift differential to buy yourself a pair of earplugs?

Writes our submitter in Michigan: “My sister-in-law graduated high school recently, and apparently calling to congratulate her — as opposed to driving 1200 miles to attend the ceremony —  was a major slight.” (A slight I’m guessing she’d be willing to graciously overlook in exchange for 50 bucks or so.)

related: Congratulations! At some point in time, through no effort of your own, you were born.

This note — from Ulladulla, NSW — is for the Aussies who were disappointed by the lack of the word “arse” in Sunday’s post from Sydney.

“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.”

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.

“I’m sure they didn’t actually paint the toilet seats,” says Brett in Syracuse. And yet, he says, when he saw this sign posted by a former co-worker, “I couldn’t stop laughing about the idea that that’s what got her.”

Perhaps a few signs like this (as spotted by Madeline at her university’s art studio) would have made for a proper rebuttal?
