On February 25, 1964, 22-year-old Cassius Clay shocked the odds-makers by dethroning world heavyweight boxing champ Sonny
Liston in a seventh-round technical knockout. The dreaded Liston,
who had twice demolished former champ Floyd Patterson in one
round, was an 8-to-1 favorite. However, Clay predicted victory,
boasting that he would “float like a butterfly, sting like a bee” and
knock out Liston in the eighth round.
