Ensign O'Toole is a military comedy that aired on NBC from September 23, 1962, to May 5, 1963, with 31-year-old Dean Jones in the title role of a nonchalant United States Navy ensign during the early 1960s. Jones, born in 1931 in Alabama and a Navy veteran of the Korean War, played an officer aboard the fictional U.S. Navy destroyer USS Appleby, which roamed the Pacific Ocean.

Phil, a part-time truck driver and singer who wears his pants far too high, meets a feisty platinum blonde who challenges him to a drag race through Griffith Park. When he is caught and loses his license, he meets up with the sketchy Frank Wooster who offers him a job singing in his new nightclub. When Phil discovers that his new job also includes drug running, he must fight to save his friends and himself.
