Pics of twin toilets in Sochi goes viral

It's a tale of two toilets.

When BBC reporter Steve Rosenberg went to use the bathroom at the cross-country skiing and biathlon centre for next month's Winter Olympics in Sochi, he found two toilets but only one stall.

His tweeted picture instantly became a national joke.

Although toilets like that are not common in Russia, social media users posted some pictures of other toilets side by side.

One said this was standard at Russian soccer stadiums.

Russians jested that the toilets in Sochi were designed for a "tandem", the name used to describe the duo of President Vladimir Putin and Prime Minister Dmitry Medvedev.

One blogger altered Rosenberg's photo to put in a framed portrait of the two leaders above the toilets.

The Sochi organising committee has refused to comment.
