Photo creates a very rude optical illusion

Did you have to do a double-take? A very rude optical illusion has left the Internet feeling flustered.

At first glance, you'd be forgiven for thinking the man in this snap has no manners.

The picture, which was posted to Imgur, appears to show a naked man lounging with his legs apart on a boat with his girlfriend.

But look again and it becomes clear that the photo is entirely innocent.

It's the woman's legs causing the confusion, as they're draped across her partner's lap, concealing his shorts.

The snap was shared online by someone who spotted the comical effect of a friend's new profile picture, and it's been viewed over a million times already.

'At first, in the thumbnail I thought he was totally naked. then I realized that was his hand,' one person wrote on Imgur.

Another said they went from thinking 'oh she's naked', to 'oh he's naked', to simply thinking 'oh'.
