Also, he is a complete jackwagon. But other than the terrible arrogance and the insistence that he doesn't need to do his best, hardly trying as he sets world records, he is my hero, on account of him being able to move his feet back and forth faster than ANYONE IN HISTORY, which is really an incredible accomplishment, considering that there have been a lot of people in history moving their feet - or TRYING TO, ha ha - in almost exactly this way.
So, in summation, Usain Bolt is a complete failure as a person, and also an incredible hero for the foot thing, which is clearly more important since he's so amazingly good at it.
