They say what goes around comes around. There’s no action that can be taken without some sort of reaction , and sometimes, that reaction doesn’t quite line up the way we think it will.
These people decided to do something, there’s a wide variety here, but what they got back was far from expected . They messed around and found out, but they just didn’t like what they found out.
“Bought a ‘brand new’ jacket online. Found this inside the pocket…”

I’m confused about the story here. Did someone steal a jacket and then forget to check the pockets? Who would steal a jacket just to resell it? Did the owner sell their own old jacket and not double-check it was empty? Why are these credit cards so pretty?
“Put my fake eyelashes on the toilet seat to scare my bf. It backfired this morning as I was half asleep opening the seat.”

That’s an extremely convincing terrifying bug, you’re a master at your awful, awful craft.
The universe couldn’t let you get away with scaring others alone, though, you also had to be scared. To understand what exactly you’re subjecting people to.
“So part of the automated chicken feeding system broke today…”

When you say ‘part’, what type of part are we talking here? because I’d say this is less ‘part’ and more ‘humungous chunk’. Also, for the chickens, this must be an absolutely glorious day. There’s food forever, whenever they want it!
“I had a friend move in due to a last minute change in his living situation.. So I got him a cake.”

The messy, hand-drawn lettering really adds to the tone of the cake. However, the bright pretty flowers introduce some humor, too, it’s an overall good move. A funny story and you both end up with some cake, it’s a win-win!
“Just got my morning coffee and I really hope this is a mistake.”

If it’s not, at least you can get out of work by spending all day in the bathroom as your stomach combats this beverage like a pirate ship fighting off a sea monster.
“My younger brother, who moves out in 2 weeks, tried to make a pizza.”

As long as he’s cooking anything that isn’t a pizza, he should be fine, right?
Or maybe any dish in the oven. Which is a lot. Just give him a microwave and tell him to stick to that for a while. When he’s ready, he can upgrade to boiling pasta.
“Went to sneak some cupcakes after my wife went to bed and found them like this.”

And you’re not allowed to criticize her even a little bit seeing as you were going to steal some! Multiple, even! Shame on you, but even more shame on all the people just telling him to cut the leashes.
“My pork ribs dinner. Unsure if stress causes short term memory loss but I put ribs on, logged into work and here we are two hours later with grill at full blast.”

I apologize for thinking this was some sort of dead fish corpse when I first saw it. Knowing the truth is actually worse seeing as it’s a rack of ribs lost to the unforgiving heat of the grill. I wish you well in your recovery from this incident.
“Lesson learned: measure your liquids before turning the stovetop on. Spent too long looking for my measuring cup.”

I was going to critique ever putting the cup in the pot to start, but as someone without a dishwasher who does his own dishes sporadically, I’m familiar with the practice of stacking dishes wherever possible and will hold my tongue.
“[Found] on my hiking trail today. [What] did tim do?!”

Well, he certainly didn’t stay on the trail, that’s for sure. And you know what? I bet he didn’t only take photos. He probably didn’t only leave footprints. Tim was running amok and they had to find a way to control him.
“Came home from vacation to find a bear had broken into my house.”

This is a reverse Goldilocks and the Three Bears situation. How much porridge did it eat? Your chairs, were they sat in? And by god, your beds, tell me your beds came out alright?
“You are NOT going to believe what happened while you were gone.”

Wow. I am shocked at the sheer amount of destruction this dog managed to cause. Like, it’s not good, it sucks for you actually, but it’s also pretty impressive. How did he even get that gate over there?
‘A fun game I like to play at work. I call it chip roulette.”

This is a surefire way to make sure your coworkers never want to talk or hang out with you, like, ever. If that’s your goal, then this is an amazing way to reach it and I admire your ingenuity.
“Angry ex?”

That, or a really bad trip behind a truck carrying cans of paint. Or maybe a long day at work, coming out to see his car like this after parking it next to a building that was getting a fresh new look. So many possibilities!
“Sigh…”

At least they proved they really wanted it, yknow? Most thieves want the whole bike these days, but this one was willing to put in the work to fashion an entire stolen bike out of individual stolen parts. They have some dedication.
“Drilled into a sprinkler pipe and soaked every apt from mine (4th floor) down.”

I didn’t really need more motivation to never do any of my own home repairs, customizations, or whatever else, but I’m happy to have it. If I ever did this by accident I’d rather move immediately than live through the shame.
“Thieves stole my steering wheel, now I can only drive straight.”

And that won’t get you very far, seeing as there appears to be another car parked maybe two feet in front of yours.
It’s time to get some vice grips and lock ’em on there, that car won’t drive to the mechanic on its own!
“Even blankets get angry.”

Sheet ghosts have grown tired of decades of mockery and caricature in modern media. They know humans don’t find them scary anymore, so they’re coming up with new methods of attack that will make us all fear them once again!
“I’m starting to think he lied on his résumé about being a guard dog.”

We’ve all fudged a thing or two on an application here and there, but you to be able to partially back it up, or at the very least own up to your lie when you face it. This dog seems to want to do neither.
“Went to the store just for black bean burgers and…”

This grocery store has taken a stern anti-vegetarian stance, which is a really weird hill to die on, but it’s their choice I guess.
That, or it’s so pro-vegetarian that the stock flies off the shelves! That’s a nicer thought.
