As you're about to see, things aren't always as they seem.
Formally known as the alpine ibex (Capra ibex), the wild goat of the European Alps goes by a wide variety of names, and covers an even-wider range of terrain.
Often going by "steinbock" or "bouquetin," the ibex is a special animal for many different reasons. First, a nice male sports some massive horns that'll turn just about any spectating head. But even more impressive is the goat's ability to traverse terrain that would leave any human shaking his or her head in pure disapproval.
At first glance, this video will have you admiring one ibex's unquestioned beauty, but not before you're interrupted by a brain-scrambling optical illusion.
Try to watch this video only once, we dare you:
There's no telling where exactly this is, but ibex are most commonly found in Italy, France, Germany, Switzerland and Austria. They were also introduced to Bulgaria and Slovenia, where they use their excellent climbing abilities to get wherever they want to go.
Who do you think would win a climbing contest? An ibex or a mountain goat? And on that note, have you ever hunted an animal that could climb better than both?
The real question is what would you do if a world record was lying in one of those holes, but was completely unreachable? Do you try to wait it out until it comes down from that spot on the mountain? Or do you just appreciate it from afar and call it a day?
