As long as presidents give speeches outdoors, there will be flies. In an age where every moment is recorded on camera, there will be videos of presidents and flies. Former US President Obama famously dispatched an annoying fly with quick smack. Costa Rican President Luis Guillermo Solis Rivera used a different tactic. He was approached by a fly when talking with reporters. The fly hovered in front of his mouth then flew in and he swallowed it. Money quote from President Rivera “You don’t see that every day.”
