An innocent holiday snap has been raising eyebrows on Reddit for a very cheeky reason.
At first glance, the image appears to show a man lying legs spread and stark naked.
But it's actually not as naughty as you think.
Look a little closer and you'll see that he’s actually wearing pants (phew) and it’s his girlfriend’s legs lying over the top of his that create an awkward optical illusion.
This image of a woman standing against a wall has also gone viral for a very rude reason.
It all looks innocent enough at first, but a trick of the light sees the shadow around the woman's knees looks suspiciously like an exaggerated male body part.
