Muhammad Ali (Cassius Clay), the "Louisville lip," holds up eight fingers in London June 19, 1963 as he predicts the number of rounds it will take him to knock out Sonny Liston if he should get a chance at the world heavyweight championship. Clay had predicted an end to his fight with British heavyweight champion Henry Cooper in five rounds and that's just what happened June 18 in London's Wembley stadium. Ali won on a technical knockout in the fifth round.
