Olympic mistakes

Who watched the Olympics on Sunday? Well, there were some quite strange mistakes and object that aren't supposed to be where they were. Firstly, there was an spider/insect on the camera lens:

   I could tell it was a spider/insect and not a distant object or a spot because it was moving. The mistake part was the fact that the presenters didn't notice and didn't brush it off.
Anyway, the object that was not supposed be where it was is the following:    

Someone threw a bottle, aiming at one of the 100m finalists. At the time, as I was concentrating on the race far more than anything else, I thought it was nothing. Nevertheless, when I turned over to the news, it said that a person was arrested deliberately trying to trow it at a player - probably Yohan Blake in lane 5.
