C.P.O. Sharkey is an American sitcom television series, created by Aaron Ruben, that aired on NBC from December 1, 1976, to April 28, 1978. The series starred Don Rickles in the title role, with Peter Isacksen, Elizabeth Allen, Harrison Page, and Richard X. Slattery featured in the cast. Rickles, who actually served in the Navy during World War II, was already well-known for the indiscriminate insult comedy he used in his stand-up routines and in guest appearances on other TV shows and specials. C.P.O. Sharkey was the third TV series that provided him with a regular vehicle for his humor. (Two previous series in which he starred, both eponymously titled The Don Rickles Show—one a 1968 variety show, the other a 1972 sitcom—each aired for one season.)
