Bare-chested Fidel Castro, Premier of Cuba, takes up a paddle against U.S. students in table tennis contest at Varadaro, Cuba, August 30, 1963. Castro challenged the students, who had gone to Cuba in defiance of a U.S. State Department ban, and said that if he lost to a student, the student would become Cuban Premier and Castro would become a student. The validity of the challenge was untested because Castro defeated all competition. (AP Photo/John F. Saltor)
