Now for the Twitter-lympics! Teams do battle on social media for the funniest Rio posts with 'dancing moobs', naked ‘Gollum’, Usain Bolt joking around... and the miserable Russians moaning about (almost) EVERYTHING

If there's one thing Team GB cannot be accused of it's lacking team spirit and a sense of humour. 

It just so happens that their competitive edge comes with a fair amount of leg pulling at their team-mates' expense.

And luckily for the fans back home, they are sharing all the results on Twitter. 

Take gold medal hopeful Luke Patience, who shared this naked photo of his unfortunate, and as yet unidentified roommate - joking: 'Sharing a room with gollum is hard work #BringOnTheGreat #bringontheclothes.'

Not to be outdone, runner Tom Farrell was getting in on the jokes - before he had even left for the airport with the perfect prank on housemate, Olympic walker Tom Bosworth.

Hiding in a cupboard, he pretended the house was empty before leaping out to surprise unsuspecting Bosworth. 

'Locked the door and made it seem as if the apartment was empty....surprise,' Farrell wrote - and shared a video of a shocked Bosworth with his followers.

Pecs Harry Aikines-Aryeetey put a clip on Twitter with the caption: 'When boredom strikes'

'Moobs': The daring video showed the sprinter's pecs bouncing along to Rihanna song Work

But it isn't just pranks being played on each other. When waiting around for your turn on the track, boredom sets in as TeamGB sprinter Harry Aikines-Aryeetey has found.

As he waited to blast down the track, the 27 filmed himself making his 'moobs' dance as his pecs bounced along to Rihanna's hit 'Work'.

Not that Aikines-Aryeetey's 'moob twerking' went down well with fellow athlete 4x100m relay runner Ashleigh Nelson.

She wrote: 'I'm here taking selfies mean while @HarryAA100m  & his pecs are twerking in the corner...What's happened?'

The Australia team didn't get off to the best start to Rio 2016.

The team said dirty bedrooms, leaking ceilings and exposed wires made their accommodation 'unliveable' and they refused to move in. 

But after organisers carried out vital repairs the team in gold and green have got their sense of humour back... and can see the funny side.

From joking around in their pink Zika-proof mosquito nets like basket ball stars Elizabeth Cambage and Tessa Lavey, to showing humility like Thanasi Kokkinakis after his tennis racquets were lost by his airline, the Aussies are winning gold in the fun stakes.

What happens when the tiniest member of the team meets the tallest? If you're Team USA, a great Twitter pic.

At 4ft 8in, pocket-sized Simone Biles is the new darling of USA gymnastics. So when she spotted US men’s volleyball player 6ft 8in David Lee towering above her in the treatment room, she saw a great opportunity.

Not to be outdone, the US women’s soccer team showed they are on point with their Twitter game - as goalkeeper Hope Solo took delight in taking a photo Megan Rapinoe's  exposed bottom when she crouched down to take a team selfie.

The men’s basketball team wouldn't be outdone at the Games. They showed confidence is sky high in a series of hilarious Instagram videos of them singing Vanessa Carlton’s 'A Thousand Miles'.

But not everyone was impressed as teammate Carmelo Anthony proved as he reacted by looking miserable and rolling his eyes.

It is a universally acknowledged truth that anything Usain Bolt touches turns to gold.

And Jamaica's self-styled 'Mr Cool' and the fastest man on the planet, has proved he is the best on social media posts too. 

Whether it be posing with the heavily armed Brazilian navy, or taking the time to visit the kids of Rio's favelas, his snaps show he he brings a sprinkling of stardust to the Games.

Star turn: Usain Bolt took time out from his preparations to hang out with the Brazilian navy

Paddling pool? Swimmers Timothy Wynter and Alia Atkinson pose in what appeared to be a kids pool - but was really an ice bath after a hard day's training

However, he isn't the only Jamaican with game on Instagram: fellow runner Shelly-Ann Fraser-Pryce has been sporting some rather amazing yellow and gold hair, putting other athletes attempt at patriotic nails into the shade.

Meanwhile, the Caribbean country's swimmers Timothy Wynter and Alia Atkinson have also made an appearance - taking dip in a what appears to be a children's paddling pool.

But looks can be deceiving as they actually cooling off in an ice bath after a hard day's training.

Hair raising: Athlete Shelly-Ann Fraser-Pryce made a very patriotic statement with her hair

Performer: But later Bolt met kids from one of Rio's poorest favelas - who were more than happy to recreate the lightening bolt with the gold medal favourite

It's fair to say that Russia has had a troubled start to Rio with their very participation in doubt until the last minute after its state-sponsored doing programme.

But now they are in Rio, they are determined put their troubles behind them.

One swimmer was so determined to show of his Games spirit he apparently managed to blow the five Olympic rings while under the water.

The synchronised swimming team, meanwhile, have embraced one of Brazil's most famous pastimes: by hitting the beach the beach.

Beach bums: Russia's synchronised swimmers have been embracing the beach life after arriving in Rio. 'Catch our positive charged boomerang,' wrote Vlada Chigiryova

Taking a dip: They were in high spirits before they left for Rio pulling funny faces...

...but the girls looked quite different as they shivered on the side of the pool 

However, they have been taken aback by the temperature in Rio - taking a snap of themselves wrapped up warm on the poolside. 

Vlada Chigiryova, who shared the image, wrote:  'We were not feeling so cold for a long time, it just makes you cry, and even hot tea does not help. 

'Your muscles get frozen, you can't operate your body and wind literally carries you to the other side of the pool.'

There have been other complaints as well - at least one surrounding the quality of coffee.

Guns: Natalia Goncharova, a Russian volleyball competitor, poses with some soldiers in Rio

Coffee complaints: Her main complaint was the lack of good coffee in the canteen - luckily it was McDonalds to the rescue

Make up: Natalia showed off some team spirit with painted nails as she boarded the flight

'Brazil is a capital of coffee but the coffee we get in the canteen is not tasty,' moaned Natalia Goncharova, a Russian volleyball competitor who blogs for Life.ru.

'Italian coaches of the Russian male team knew it ahead and even brought a coffee-machine. They live just one floor above us but we don't want to push them for sharing it with us yet.'

Here's hoping Italian-Russian relations stay strong.

Polish athletes plan to clean up at Rio2016 - starting with their hotel rooms.

Artur Mikolajczewski, 26, who represents Poland in rowing posted these photos of his filthy room in the Brazilian Olympic Games city.

In one, the rowing champ shows a filthy mattress. Another shows a grim bathroom sink, while another shows a broken wall socket.

Dusting: Rower Artur Mikolajczewski is also hard at work in his room, wiping the windows

Pitching in: They've even got the coaches on duty, including handball's  Talant Duyshebaev

Mikolajczewski wrote: 'At first glance, everything seemed beautiful, pretty, with new skyscrapers and a nicely prepared village but what we found inside the building is, to put it gently, a tragedy.

'Just dirt and filth. At the moment we are faced with piles of dust and a toilet that doesn't work.

'We don't even have clean beds - just dirty mattresses without sheets.'

He then posted a photo of himself cleaning the windows of the hotel before going outside and sitting on a Rio2016 sign and pretending to row it home.

He was joined by the Poland's Olympic handball team who uploaded pics of themselves cleaning up their filthy hotel room.

Bored: Wimbledon hottie Agnieszka Radwanska tweeted a picture of herself looking fed up at an airport She captioned the pic: 'Second day on the Road to Rio… Still not even close…'

Chores: Rower Artur Mikolajczewski got so fed up of the conditions in his room that he started to 'row' home

The team posted: 'We got to the village, it's time to get to work, we start with cleaning' alongside pictures of them with mops and coach Talant Duyshebaev, cleaning windows.

Meanwhile, Wimbledon hottie Agnieszka Radwanska tweeted a picture of herself looking fed up at an airport She captioned the pic: 'Second day on the Road to Rio… Still not even close… .' 

The Germans are known to be serious people, so perhaps it is no surprise that the team eschews silly selfies in favour of a good puzzle.

Because that is exactly how the country's canoe slalom team spent their evening - even sharing a picture of the excitement of the 1,500 piece puzzle with their followers.

There were more serious problems to be dealt with though.

Puzzling: Germany's canoe slalom team enjoys an evening of light entertainment with fun and games

Advice on what colour bag to take backfired somewhat, according to Germany's official Olympics Twitter feed which posted a picture of dozens of red suitcases at Rio's airport.

'We have landed. Take the red ones, they said, they are easy to find,' they wrote. 

'But which one belongs to whom?' 

Baggage: It turns out even the organised Germans get things wrong sometimes. 'Take the red ones, they said, they are easy to find. But which one belongs to whom?'

If the Germans are taking life a tad too seriously, the same cannot be said for their neighbours from the Czech Republic.

The Czech team is clearly loving life in Rio - touring the Olympic Village by scooter, sipping from coconuts on the beach and dive bombing into the pool.

And then there's their little mascot stickman who has made a few appearances jumping from one balcony to another....

Smiles: The Czech sailing team enjoy a coconut refreshment on the beach during training

Dive bombs: Rower Lukáš Helešic takes advantage of an empty pool in the Olympic Village

It's not the award the Canadians thought they'd be taking home from Rio, but the medal for best selfies surely has to go to them.

Canada's hockey team showed off one of the best selfies of the tournament, overlooking Rio from the base of Christ the Redeemer.

Larking around: Rudy Verhoef shows the rest of the Olympic Village how to turn an everyday moment into the perfect shot of the team with the aid of a selfie stick

But their skills aren't confined to tourist attractions: this team can turn a walk around the Olympic Park into the perfect selfie moment - as proved by Rudy Verhoef, a volleyball player. 

It's not just selfies, either. They've been getting creative with their poses on the Olympic rings in the village, and been crowding around the Games mascots for some of the smiliest pictures of Rio so far. 

Iconic: The Canadians get creative with the Olympic rings - because you can 'never have' too many shots of the athletes posing in the iconic symbol

Mascot: The team were delighted to share a picture of them crowding round the Rio mascot

The South African rowing team are certainly taking the Games seriously  - but are managing the odd Instagram post in between training.

Kate Christowitz shared a picture of the female rowers relaxing in the ice baths after 'a slightly hard six km'.

But the boys weren't going to be beaten, with  James Thompson sharing a picture of a very empty canteen at 5am in the morning.

Breakfast: James Thompson also showed off a rower's hard life with this 5am canteen shot

 'Olympic village dinning hall at 5am, basically an international rowing athletes get together.' he noted.

The rowers might be working hard already, but the rugby sevens team was making the most of a bit of downtime after the long flight from South Africa.

Seabelo Senatla was delighted to discover his first Brazilian palm tree, along with a refreshing coconut.

Teammate Philip Snyman meanwhile shared a snap of himself under Christ the Redeemer during a spot of sightseeing.

Gold medal hope Caster Semenya, meanwhile, had awarded herself a 'cheat day'.
