Boy 'shadowboxes' next to hearse carrying Muhammad Ali

As the body of Muhammad Ali made his way to the KFC Yum! center in Louisville, it was greeted by mourners chanting his name and throwing flowers on it.

Throughout the procession through the streets of Louisville, many people ran up to the vehicle and tapped on the windows to say goodbye to the icon.

One boy ran alongside for a few seconds and 'shadowboxed' right next to him. The moment was enough to give some people chills.
