Fifty years ago today this happened.

In front of just 2,400 spectators in tiny Lewistown, Maine, Muhammad Ali knocked out Sonny Liston in one of the most talked-about sports moments of all time. Ali, who had publically converted to Islam and changed his name from Cassius Clay since his previous bout (also a defeat of Liston), retained the WBC World Heavyweight title. The fight lasted about two minutes… the picture forever.

God damn what a great picture.
