Many viewers might remember a funny incident during the second round of TV debates between the US presidential candidates, when a fly landed on the Democratic Party candidate Hillary Clinton's brow. The fly was sitting on Clinton’s brow, while she was responding to the subsequent question. It did not distract her attention, as if she did not notice it at all.  Soon it became the subject of heated discussions in social networks. There were created several accounts in Twitter against this background, run allegedly by the fly, reports the  Newsru.  “Showing my support for Hillary! I can't believe I'm on TV!”
