Usain Bolt was so fast in his 200m semi-final that he had time to share a joke on the finish line.
The Jamaican was seen laughing with Canadian Andre de Grasse as the pair finished first and second to reach the final in Rio.
Bolt, as he always does in heats and semi-finals, started jogging midway through the race and was rather surprised to see De Grasse next to him on the finish line.

The only way in which the 21-year-old could catch up to Bolt would be, of course, by continuing to sprint.
And given that this was only the semi-final, watching De Grasse exert energy in an attempt to overtake him - which wasn’t necessary, considering the first two went through - surprised the world’s fastest man.
“Andre was supposed to slow down. He didn’t,” Bolt said afterwards in an interview with the BBC.
“I said: ‘What are you doing, it is the semi-finals?’ He said he had to push me.”
The Jamaican is one step closer to achieving an unprecedented triple-triple - winning the 100m, 200m and 4x100m in three straight Olympics’ - but he’ll have to overcome some tiredness that he admitted has carried over from his 100m victory.
“I was a bit lazy, I don’t know why,” the 29-year-old added. “But I executed it.”
Bolt will take to the blocks on Thursday night knowing that it will be a miracle if he doesn’t win an eighth Olympic gold. That must be an incredibly calming thought.
