Whether our eyes light up like a magpie or we're sketched out by what we find, we can usually at least tell what we've come across. We might not know how diamonds came to be scattered on the street (we wish) or why someone's toothbrush ended up in an alley, but it's at least clear what we're supposed to do with those.
But sometimes, there comes a time when we stumble across something that only leaves us scratching our heads. However, it seems that some among us have figured out what you're supposed to do when that happens as well.
From the looks of it, you take a picture and share your strange discovery with the internet.
