We simply can’t know everything . There will be a lot that we encounter day after day that we have no information about. We hope that someone will come along and explain it to us, but there’s a chance no one will, and we’ll be left with the mystery forever.
That’s what happened to the people in this list, who found weird things that simply can’t be explained.
“Throwing away a few year old (other than that practically brand new) cases that we sell for $40 each. I asked to take a few home because I have an older phone, was told that it is considered stealing.”

This post actually got a lot of traction, and the comments encouraged the uploader to go back and take them from the dumpster, which they did. They then proceeded to give away cases to people in the comments who contacted them. A local hero!
“Went for a walk and this is how a street light shining through tree leaves looked. My normal shadow next to it.”

This happens from time to time, your graphics just need tweaking and your game might need a restart to fix it. Or maybe your computer is just rendering them slowly, wait a minute and see if they fix themselves before messing with settings.
“What’s the ‘U’ on this kids carpet?”

People were quick to point out that this is, in fact, an urchin. That doesn’t make it a good urchin, though. It looks more like a cartoon rendering of an amoeba, or a rather nasty stain with a face on it.
“This person checked out yesterday.”

The people who caused this mess apparently only stayed for two days, and of course, when it came time to pay, their card declined. How someone can cause this much of a mess in such little time is astounding, let alone not feel any shame for it!
“This big ol knife angel in my town.”

This is a stunning sculpture, but something about it being advertised as just ‘knife angel’ is very funny.
I feel like those barriers are a little weak for a sculpture made of knives. Someone is definitely going to hop that and get themselves stabbed.
“[My roommate] washed my pullover for me.”

And in the process made a brand new pullover for a child instead. It’s like regifting, but you still wanted it and it was a mistake.
In your roommate’s defense, nothing should be shrinking this much after going in the dryer. That’s a bit excessive.
“My son’s Spongebob activity book is missing the word Squidward in the word search.”

The angry annotation really sells this. Next time he’s flipping through the book he’ll see that and be reminded that this book is a disgrace and not worth his time. He should mail it back to the manufacturer like this, open to this page.
“A stranger threw a bucket of water on my cat.”

Though the act was random and inexplicable, someone in the comments provided a nice perspective, “I always look at this as a win, less likely kitty will go there again and the guy didn’t kill the cat. It’s the arseholes that do you need to worry about.”
“Found this rock with odd shaped hole.”

In a video game, you’d need to complete a quest or search the area to find the ancient treasure that would fit perfectly into this slot. Then it would spin and the whole rock would open up to reveal a chest or a secret door.
In this case, there’s probably just more rock inside that rock.
“Vein finder we use in the hospital to place IVs in our ‘hard stick’ patients.”

Medical science and technology is amazing. Do you mean to tell me there’s a light that you can shine on someone’s body that reveals their circulatory system? That straight-up sounds like science fiction, it’s so cool!
“My university has a door halfway up the side of a building.”

Don’t most universities have extreme locks and barriers on their windows for fear of a student ending up through one? But a door like this is allowed to just exist up there without any issue?
“This man proceeded to dig 50+ holes at our local park to indulge his metal detecting hobby.”

The number of detectorists (so I learned they’re called) who showed up to the comments to shame this man’s behavior was astounding. Let it be known that these actions are not condoned by metal detecting fans, he does not represent the hobby!
“This tiny electric car.”

Who decided that this car needed to have a full front end? Who? Why does it only have three wheels? Who is this product for? There are both better electric cars and better compact cars that blow this Frankenstein’s monster out of the water.
“A blue burst on my images caused by waterdrops.”

You look ready to film a comic-book-styled movie with effects like this going on. Or a sci-fi/paranormal flick from the ’80s. Your pick! You either get to superimpose some comic onomatopoeia text, or a spooky, poorly rendered ghost!
“Apparently someone has been munching my donuts and it was supposed to be for my kids after work.”

Who one earth does this? Really, who goes through someone’s mind that makes them want to do this? Whoever it is, I fear they’re one minor inconvenience away from turning into a full-blown supervillain if this is the type of thing they do now.
“My fathers forged [Taiwanese] student pass from the 80s (he’s never been to [Taiwan]).”

If you’re wondering why anyone would do this, the uploader went on to explain, “My father was in mainland [China] in 1987. At that time there was no communication between mainland [China] and [Taiwan], but [China] [officially] claims [Taiwan].
“So my father got this forged [Taiwanese] student pass made in Hong Kong that could not be checked for validity on the mainland. This way he could still use all kinds of student discounts without actually being a student.”
“This advertisement my kids school slapped on my daughter.”

I understand brands marketing towards children to convince their parents to buy something. I don’t like it, but I understand it. This feels like an absurd escalation of that, though. It’s not only on the business, but the school for allowing it and making teachers go through with it!
“Just another bike. But more fabulous.”

Yeah, alright, I guess that’s true. I hope the person riding it is tall enough that the horn right in the center doesn’t block their vision at all. It’d be a shame to crash on such a majestic steed.
“This woman taking those two seats and the one at the other side while a man is standing. She wouldn’t let him sit down at all.”

Do these people not know public transportation etiquette, or do they know and they just refuse to practice it? I don’t know who crowned this woman Queen of the bus, but I’d like to have a word with them as it’s not very fair.
“1:30 in the morning in a local park in the high desert…I find this among the bushes…this park is freaky.”

The blurry photo really makes this found-footage horror movie potential. I can’t even tell what those are exactly. Candles? Lamps? Diffusers? Humidifiers? The possibilities are endless!
