John Francis Burns (November 15, 1933 – January 27, 2020) was an American comedian, actor, voice actor, writer, and producer. During the 1960s, he was part of two comedy partnerships, first with George Carlin and later with Avery Schreiber. He is perhaps best known for his short stint as "Warren," Barney Fife's deputy replacement on "The Andy Griffith Show" in 1965. By the 1970s, he had transitioned to working behind the camera as a writer and producer on such comedy series as The Muppet Show and Hee Haw. Biography Burns enlisted in the United States Marine Corps in 1952. It wasn't long before Burns realized a military life was not for him: "the first week of boot camp changed my mind." He served in Korea, rose to the rank of sergeant, and was discharged around 1954. Burns began his comedy career in 1959, when he partnered with George Carlin; both were working for radio station KXOL in Fort Worth, Texas. After successful performances at a Fort Worth beat coffeehouse, The Cellar, Burns and Carlin headed for California in February 1960 and continued to work together for two more years. 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 troupe 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. During the summer of 1973, the two appeared on the ABC TV variety series The Burns and Schreiber Comedy Hour. During the first half of the 1965–1966 season of The Andy Griffith Show, in an attempt to replace Don Knotts' Barney Fife character after Knotts left the show, Burns was cast as Warren Ferguson, a dedicated but inept deputy sheriff. His character was not popular, and was dropped after 11 appearances. In 1967, he was cast as "Candy Butcher" in The Night They Raided Minsky's. In 1971, he was cast as Mr. Kelly in The Partridge Family episode "Dora, Dora, Dora,” (S2/Ep1). Hanna-Barbera gave the voice of Harry Boyle's reactionary neighbor, Ralph Kane, to Burns in the short-lived syndicated prime-time cartoon Wait Till Your Father Gets Home. The series was a forerunner of adult animation comedies. Burns
