Forget Super Saturday - in Rio, it was all about Super Sunday.
Great Britain won a mighty five gold medals to leapfrog China into second place in the medals table. Meanwhile, there was the small matter of the 100m final... here's exactly what you need to catch up on from day nine.
Usain Bolt made us all wonder once again if he's actually human
The Jamaican became the first man to win three Olympic golds in the blue riband event, landing his seventh crown overall by recovering from an awful start to blast to victory in the 100m - with a time of 9.81 seconds.
Man. Bolt's last 50 meters are incredible.

It is taking me longer to type this tweet than it took Bolt to run and win his event

The 29-year-old was down at halfway and had to work harder than expected to overhaul two-time drug cheat Justin Gatlin, who took silver in 9.89 seconds, with Canada's Andre de Grasse winning bronze in 9.91 seconds.
Max Whitlock smashed history - and all expectations - by taking home two gold medals
Everyone thought Whitlock stood a good chance of taking the gold on the pommel horse, being the world champion and all - and he did, leaving teammate Louis Smith to come second with silver.
But no-one thought he would bag the top spot for his routine on the floor - and yet he did that too, making him Team GB's first Olympic gymnastics champion, ever.
I cannot believe Max Whitlock just won the first ever Olympic gold for GB in gymnastics and could win another in the same night ?? #GBR

Andy Murray made his own Olympic history
In a match that seemed to go on forever (it was four hours long to be exact), the world number two won against Juan Martin Del Potro 7-5 4-6 6-2 7-5 to make it back-to-back titles. This makes him the first tennis player ever to win two singles gold medals.

Simone Biles added more golds to her collection
The 19-year-old superstar won her third gold of Rio with a brilliant performance in the women's vault (as if we ever doubted it would be) and with quotes like this, is fast becoming one of our favourite athletes.

We won gold in the golf thanks to Justin Rose
So having golf in the Olympics WAS a good thing, after all.
Me 1hr ago:"Golf is not an Olympic sport" Me now: "Come on Justin!!!!!" Whoop!! ???

Giles Scott also got a gold for us in the sailing - even though the medal race hasn't even happened yet
Scott's performance in the men's Finn class put Team GB at an unbeatable lead ahead of Tuesday's medal race, meaning we've got a guaranteed gold. That's some *serious style*, we agree.

Jason Kenny won his fifth Olympic gold - so people are calling for him to be knighted
Sir Jason Kenny anyone? #nightfolks
It was an all-Team GB affair in the final of the men's sprint.
Kenny won the opening two races to clinch gold leaving team-mate and room-mate Callum Skinner with silver. Kenny joins fellow cyclist Sir Bradley Wiggins and rower Sir Steve Redgrave on five Olympic gold medals - and winning Tuesday's keirin could make it six.
And there was even an Olympics love story...
Chinese diver He Zi had already had a great night after winning a silver medal in the women's 3m springboard final. But then fellow diver Qin Kai proposed to her during the podium ceremony.
Awkwardly, there was a bit of a long wait for the crowd before she answered...but don't worry, she said yes. N'awwww.
