If there are two things the internet loves unconditionally, it is dogs and optical illusions - and fortunately, this adorable but mind-boggling video rolls them both into one.
Pet owner Gina Creuz of Hazlet, New Jersey, recently shared a video of her beloved a one-year-old American Bulldog tackling the household stairs in a very unique manner.
However, after the 53-year-old owner shared the clip online, people couldn't decide whether or not her pooch - named Groot - was going up the stairs or down them.
Check out the clip below to see what you think:When I first watched it, I definitely thought Groot was hopping up the stairs, but apparently he is - SPOILER ALERT - actually hopping down them!

This was confirmed by Gina who said: "Love my pup and his odd way of hopping down the stairs.''
However, people on Twitter were not convinced:





This is far from the first time a post has left the internet stumped.
February 26, 2015, will go down in history as the day millions of people could not decide whether a dress shown in a picture was blue and black or white and gold. (It's obviously black and blue.)
Fast forward nearly five years, and the internet was once again in disagreement over a man on a swing.
On December 21, a video was posted to TikTok showing a man on a swingset in the snow, but due to the fact he is quite far away from the camera, it is difficult to see which way the man is facing.
So, which way do you think the man is facing? (It's obviously towards the building.)The video was originally uploaded to TikTok by use ectupper, and was later reposted to Twitter by the account esnycuddles.
As of this writing, the video has had over 10,000,000 views and been retweeted over 23,000 times.
But people are torn. Is the man facing the building or the camera??
So which side is the man facing? Let us know what you think in the comments section!
