Clay, who later changed his name to Muhammad Ali, points to a sign he wrote on a chalk board in his dressing room before his fight against Archie Moore in Los Angeles, predicting he would knock Moore out in the fourth round, which he went on to do. The sign also predicts he'll be the next champ via a knockout over Sonny Liston in eight rounds. He did it in seven rounds.
