You've probably seen that ancient optical illusion image of rabbit and a duck before, right?
It's basically The Dress before the Internet or a precursor to any of those lazy-eye optical illusion images you see. We never saw anything in those, for the record.
Here's the original image you may be familiar with...
...and here's an actual, real-life version of the same.
This image, which was posted on Imgur yesterday, has been driving people slightly mad. Not to go all Don Conroy, but that's a male Common Goldeneye duck and it's performing a courting ritual. The duck bobs its head back into the water and quacks to try and attract females to them.
That's neither here nor there, of course. IS THIS A DUCK OR A RABBIT? Well, it's a duck, obviously. But what do you think?
