Rio Olympics 2016: The most memorable moments

The Rio 2016 Olympics have provided an abundance of memorable moments. Here are some of the best - good, bad, and ugly.

Tongan flag bearer

One of the first Olympic moments to go viral happened when Pita Taufatofua, Tonga's flag-bearer, appeared at the opening ceremony. The taekwondo athlete emerged topless, wearing traditional Tongan dress and apparently covered in baby oil. It did not go unnoticed.

Opening ceremony had warmth, passion and hope

Ragan Smith and Deandre Jordan

Michael Phelps

It wasn't always so friendly in the swimming pool. Twitter went into meltdown after swimming legend Michael Phelps was pictured giving rival Chad le Clos a "death stare". He was caught putting his game face on while in the warm-up area of the Olympic pool, prompting #Phelpsface to trend on Twitter.

Rafaela Silva of Brazil celebrates

The first golden moment for the host nation - the story of Brazil's 57kg judo champion Rafaela Silva shone a light on some of Rio's poorest residents. From one of Rio's toughest neighbourhoods, the so-called City of God, Silva was disqualified at London 2012 and later labelled an embarrassment. Her victory marked a fairytale rise.

Michael Phelps leads Chad le Clos in the Men's 200m Butterfly Final

It wasn't long before Phelps, the most decorated Olympian of all time, broke into a smile, beating le Clos of South Africa in the men's 200m butterfly final. Some suggested le Clos should have been looking where he was swimming rather than watching his rival.

Rami Anis, swimming for the Refugee Olympic Team

It was not all about the winners in the pool. Rami Anis - a swimmer for the refugee team who fled war-torn Syria in 2015 before travelling by boat across the Mediterranean Sea to Turkey - earned a standing ovation after setting a personal best in the men's 100m freestyle.

Lifeguard in the Olympic swimming pool

It wasn't just the swimmers attracting all the attention. Some bored-looking lifeguards - who had been charged with watching over the best swimmers in the world - caught the attention of many people on social media.

Green pool

The colour of the water at the Maria Lenk Aquatics Centre became a major talking point, after it turned from aquatic blue to a murky green overnight. Games organisers blamed chemical levels in the water.

Katie Ledecky leads the women's 800m freestyle Final

American swimmer Katie Ledecky dominated in the pool, taking nearly two seconds off her own world record to win the women's 800m freestyle final in eight minutes 4.79 seconds - finishing nearly 12 seconds clear of the rest of the field. She also won the women's 200m freestyle, the 400m freestyle and the 4x200m freestyle relay.

Singapore's gold medallist Joseph Schooling, who idolised Michael Phelps as a child, managed to get the better of his hero in pool, winning the 100m butterfly ahead of Phelps, Chad Le Clos and Laszlo Cseh - who finished joint second. A photograph of a young Schooling, then just 13, with Phelps at the Beijing Olympics in 2008 quickly went viral.

Laurine van Riessen of Netherlands and Virginie Cueff of France crash

One of the images from the track cycling came when Laurine van Riessen, of the Netherlands, managed to avoid a nasty crash with France's Virginie Cueff by riding up and along the barrier at the side of the track. Such was the extent of her precautionary action, she became almost horizontal.

Aurimas Didzbalis of Lithuania flips in the air

Some athletes were disappointed to miss out on gold, or with having to settle with a mere silver or bronze medal. Not Aurimas Didzbalis of Lithuania. The weightlifter celebrated pocketing a medal in the men's 94kg with an impressive back flip.

Mo Farah

A nation gasped when he tripped and fell, but despite taking a mid-race tumble, Britain's Mo Farah became the first British track and field athlete to win three Olympic gold medals as he retained his 10,000m title with a thrilling victory.

Bradley Wiggins

It wasn't all tears on the podiums. Britain's Sir Bradley Wiggins instead poked out his tongue to celebrate winning the men's cycling team pursuit - his fifth Olympic gold medal. He also became the first Briton to win eight Olympic medals.

Chinese diver He Zi had just collected her silver medal in the 3m women's springboard final when fellow diver Qin Kai entered the podium presentation. He duly got down on one knee, produced an engagement ring and proposed. She said yes.

Usain Bolt in

Never far from the spotlight, Jamaica sprinter Usain Bolt managed to find time to smile for the cameras while easing to a 100m semi-final victory. It prompted a flurry of internet memes. He later won the final in a time of 9.81 seconds - his third 100m crown in three Olympic Games.

Wayde van Niekerk

How do you upstage Mr Bolt? Why not break a world record less than half an hour before the great man was due to run in the 100m final? South Africa's Wayde van Niekerk shattered Olympic legend Michael Johnson's 17-year-old 400m world record by 0.15 seconds to sensationally win Olympic gold. Apparently the credit goes to his 74-year-old great-grandmother - who happens to be his trainer.

Kiribati's David Katoatau

How can you forget a dancing weightlifter? Big David Katoatau, from Kiribati, threw some shapes every time he successfully made a lift. He finished sixth in the men's 105kg Group B final but certainly kept the crowds entertained.

Shaunae Miller dives across the finish line

Shaunae Miller of the Bahamas somehow managed to win a dramatic gold medal in the women's 400m final - by diving over the line. Miller stumbled in the final stages and then lunged forward as she headed towards the track, edging out American world champion Allyson Felix to win in 49.44 seconds.

Ireland's Michael Conlan

Ireland's bantamweight Michael Conlan went out of the boxing tournament in the quarter-finals - losing on points to Vladimir Nikitin of Russia. Conlan was furious at the verdict, which was booed by the crowd, and he vented his frustration at the judges afterwards, saying he had been "robbed" of his dream of winning Olympic gold.

Jason Kenny and Laura Trott kiss

A golden night for Britain's golden couple. Laura Trott first won gold in the women's omnium - following up her victory in the women's team pursuit. She then had to sit trackside as fiance Jason Kenny won his third gold of the games and his sixth in total in a dramatic keirin - which twice had to be restarted. One relationship, 10 Olympic gold medals. Not bad.

Renaud Lavillenie

There were tears on the podium for France's Renaud Lavillenie, but for all the wrong reasons. The pole vault silver medallist was booed by the Rio crowd for a second time in 24 hours, having lost out to home favourite Thiago Braz da Silva in a dramatic final.

US Olympic swimmers Gunnar Bentz and Jack Conger

One of the most bizarre stories from Rio involved American gold medal-winning swimmers and a petrol station. Ryan Lochte, Jimmy Feigen and Jack Conger became embroiled in an international scandal over a made-up robbery. It became an Olympic mystery and resulted in a police investigation and a series of apologies.

Alistair Brownlee and Jonathan Brownlee of Great Britain celebrate during the Men's Triathlon

Was it fratricide? Was it brotherly love? It definitely ended well for the Brownlee brothers, Alistair and Jonny, who won gold and silver in the men's triathlon. The image of the British brothers collapsing into each other arms at the finish line will live long in Yorkshire memories.

Usain Bolt and Camada's Andre De Grasse in Rio taking part in the 200m semi final on August 17 (Brazil time)

Unperturbed Bolt, once again, shows his gregarious personality by pointing in admiration at Canada's Andre De Grasse as both men cross the line - in first and second place respectively - in the men's 200m semi-final. Bolt went on to win the final, of course.

USA's Morolake Akinosun competes in the women's 4 x 100m re-run

Morolake Akinosun ploughed a lonely furrow down the home straight after the USA women's 4x100m relay team was allowed to re-run their heat after dropping the baton. They successfully argued they had been obstructed in their first race and ran on an empty track to qualify for the final. All the extra effort was worth it as the USA went on to win the final in 41.01 seconds - the second-fastest time in history.

Great Britain"s Nick Skelton

Nick Skelton became Britain's second-oldest Olympic gold medallist when he won the individual show jumping event. The 58-year-old, who had retired in 2000 after breaking his neck in two places, triumphed after a six-way jump-off. The only person older than Skelton to win gold for Britain was shooter Joshua Milner in 1908 - aged 61. Skelton will not beat that record as he has ruled out competing in the Tokyo Games in four years' time.

Abbey D'Agostino and Nikki Hamblin

The true Olympic spirit shone out when New Zealand's Nikki Hamblin (left) and Abbey D"Agostino of the USA helped each other out after colliding in their heat of the women's 5000m. D'Agostino tore her anterior cruciate knee ligament in the incident but both runners insisted on completing their race. They were both handed places in the final but the injury prevented the American taking part.

Usain Bolt

The triple triple? The treble treble? However you dress it up, Usain Bolt has nine Olympic medals from three Olympic Games. He said victory in the 100m, the 200m and the 4x100m relay would make him "immortal". It is hard to argue.

Bolt's amazing Olympic career in numbers

Neymar and his Brazil team-mates celebrate victory in the Olympic football final.

Brazil exorcised the demons of their 7-1 defeat by Germany in the World Cup semi-final in Belo Horizonte in 2014 by beating them in a penalty shoot-out to win the Olympic gold medal. The match had finished 1-1 after extra-time and star striker Neymar, who missed the World Cup humiliation because of injury, scored during normal time before converting the decisive penalty and bursting into floods of tears.

Mo Farah poses for a selfie with a fan after winning the 5,000m.

Britain's Mo Farah completed the double double as he became only the second man, after Finland's Lasse Viren, to retain both the 5,000m and 10,000m Olympic titles. His four gold medals make him his country's most successful track and field athlete.

Closing ceremony

After the competition, came the party as Rio produced a carnival-style closing ceremony full of music, dancing and colour.
