First, it was the dress debate back in 2015.
Was it white and gold or blue and black?
To this day, it's still up for debate.
But now, there's a new optical illusion driving the internet crazy.
The video shows someone petting an animal's head, but is it a bird or a bunny.
The answer: It's a bird!
Officials at the World Bird Sanctuary in Missouri confirmed that it is an African White-necked Raven named "Mischief."
According to the World Bird Sanctuary, Mischief is pretty talented too.
The bird can apparently talk, paint and best of all, confuse the internet.
