O. K. Sato

O. K. Sato (March 13, 1871 - March 23, 1921) was an American vaudeville performer who was active in the late nineteenth and early twentieth centuries. His act was notable for its juggling of the comedic style and was an early use of the so-called "tramp" juggling style popularized by W. C. Fields. In fact, Sato and Fields are known from Fields' surviving correspondence to have maintained a relationship in which the two traded gossip and ideas for their acts.
