You might be thinking Usain Bolt is the fastest thing to happen at this summer's Rio Olympics. However, you would be wrong.
Whilst Bolt was sprinting to yet another gold medal at the Olympics in the 100m final, there was a bloke in his own front room who was challenging him to a sprint challenge.
The man might not have been running 100m, but he was trying to complete a Rubik's Cube, and he was trying to complete it before Bolt could finish his race.

The Jamaican sprinter finished the final in 9.81s, but that was outdone by the Rubik's Cube man, who managed to complete his challenge just before Bolt crossed the finish line.
In the video of the man completing the Rubik's Cube, you could hear people getting excited in the background, and they were delighted when he managed to get the job done just before Bolt could.
The fastest ever Rubik's Cube completion stands at 4.90s, which is held by Lucas Etter, who recorded that time during the River Hill Fall 2015.
As for Bolt, he will have to settle for yet another gold medal and a fact that he can complete the 100m in a record time of 9.58s, which he achieved back in 2009.
You can watch the video of Usain Bolt vs the Rubik's Cube below.
Bolt's gold medal at the Rio Olympics was his seventh gold at a summer Games, with three coming in Beijing and three more coming in London 2012.
However, he will have to run a considerable amount faster if he wants to surpass the man's Rubik's Cube making skills.
What's more impressive? Usain Bolt or the Rubik's Cube? Have YOUR say in the comment section below!
