President Donald Trump's epic farewell handshake seemed to pull the president of France off balance. The handshake between Trump and Emmanuel Macron, which came as the U.S. president took part in a spectacular Bastille Day parade on Friday, seemed to go on and on. Eventually, France's first lady joined in. They finally let go after a staggering 28 seconds. During the parade, the French military's marching band performed an incredible medley of Daft Punk tunes for the world leaders.
