Bizarre optical illusion appears to show a man riding a motorbike while NAKED (Details, pics)

At first glance, the picture appears to show a naked man riding a motorbike with a girl sitting behind him. But a closer look suggests that not all is what it seems, as there are another set of legs in the picture.

The bizarre optical illusion, shared on Reddit, has left social media users completely baffled - with many confessing they couldn't work out what was going on.

Some Reddit users said they believed there was a mannequin in between the man and the woman, while others thought there were three people riding the bike.

In actual fact, the man in the photograph is topless and wearing jeans, while the girl behind him is wearing tiny shorts.

Her bare legs have blended in with his torso in the picture, creating the strange illusion of him being naked.

Despite the simple explanation, many people admitted they had been left completely baffled by the photograph. Others admitted they were 'still seeing a naked guy' in the picture - only realising the truth after someone else on the thread explained what was going on.

It comes after another mind-boggling picture also left social media users scratching their heads, after seeing a picture that apparently showed a people at a music festival. However, the confusing picture actually showed a combine harvester driving through a cotton field.
