Jack Burns (born November 15, 1933) is an American comedian and voice actor. In 1959, he began his career as a comedy team with George Carlin when both were working for radio station KXOL in Fort Worth, Texas. After successful performances at Fort Worth's beat coffeehouse, The Cellar, Burns and Carlin headed for California in February 1960 and stayed together for two years as a team before moving on to individual pursuits. An album containing some of their material was released in 1963, titled Burns and Carlin at the Playboy Club Tonight. Longer lasting was a later teaming with Avery Schreiber, whom he met when they were both members of The Second City, a live comedy and improv club based in Chicago. Burns and Schreiber were best known for a series of routines in which Burns played a talkative taxicab passenger, with Schreiber as the driver. Burns played the dedicated but inept deputy sheriff Warren Ferguson during the first half of the 1965-1966 season of The Andy Griffith Show, as Barney Fife's replacement after Don Knotts left the cast. His character was not popular and was dropped without explanation after eleven appearances.
