It was supposed to be a cute picture of a couple sitting on what looks to be a lovely boat on a beautiful day. You know the type. It's usually a weekend thing on your social media feeds.
But if you were mindlessly scrolling through your Facebook and came across this snap you might have to do a double take.

No, that's not a guy with his trusted sidekick out in the sun while his girlfriend gives him a loving embrace, it's one of those classic illusions.
It's not an illusion where if you stare at it for long enough it fries your brain, but it's one of those images you have to glance at twice to know what's going on.
Reddit user Summerie uploaded the picture, saying: "My friend posted a new profile picture with her boyfriend, and everyone took a double take."
One Redditor couldn't believe their eyes, explaining: "At first, in the thumbnail I thought he was totally naked. Then I realised that was his hand. Then I clicked it and realised it was her legs. Then I went back to the thumbnail, and I thought they must've done that intentionally. Then I clicked it again and realised they didn't. This post has been an absolute emotional rollercoaster for me."
Another person thought it was quickly becoming another blue and black versus white and gold dress scenario, claiming: "What I can't understand is the fact that I saw exactly what you described, but then as soon as I saw what's actually there, I can't really see the naked guy anymore. I can't comprehend how that's what I saw, but it 100 percent was."
The internet went a little wild when Eleanor Bailey uploaded a picture to Twitter of her friends out at a club in the Netherlands.
To be fair, I've just spent five minutes trying to work it out. Turns out I wasn't alone.
But luckily one Twitter user came to our rescue and posted an explanation:
Now all is good with the world.
