US Presidential Debate 2016: Social media frenzy over fly that landed on Clinton's face

Social media was buzzing after a fly landed on Hillary Clinton’s face during the second presidential debate.

Clinton didn’t seem to notice the fly -- who already has a Twitter account named “Hillary Clinton Fly” -- land on her eyebrow.

It quickly flew away but it sent social media into overdrive with people questioning if it really just happened.

Users have compared the fly landing on Clinton’s face to scenes from the sci-fi television series Westworld, where flies land on the faces of robots.

Some social media users have said Clinton should next time deem the debates a "no fly zone".

Thousands of other social media users chimed in on the 90-minute presidential debate, many mocking Donald Trump’s performance.
