Usain 'Lightning' Bolt strikes again.
He wore a practice t-shirt with the words 'Ich bin ein Berliner' on it, and he wasn't joking. Berlin has definitely been his town over the last few days.
Fresh off of breaking his own world record in the 100m final a few days ago, he set his sights on eradicating his one year old record in the 200m that he set during last year's Beijing Games.
And just like in the 100m meter final, he lowered the record by .11 seconds.
This may have been the stadium in which Jesse Owens triumphantly won four gold medals in 1936, but Usain Bolt and his Jamaican track teammates are turning it and these World Track and Field Championships into their own personal playground.
In addition to setting five world records in his last five major races, Bolt is the first and only track athlete to simultaneously hold the Olympic and world records in the 100m and 200m.
The only question left for the world now is whether he'll win the 100m and 200m in the same record breaking fashion in London two years from now.
