 Goober was Gomers cousin, mentioned as early as 1962 but not seen  until the April 1963 episode "Fun Girls". That episode was also the  only time Gomer and Goober appeared on screen together during the  series (though they did also appear together once on  _"Gomer Pyle, U.S.M.C." (1964)_ (qv) and in the reunion TV movie  _Return to Mayberry (1986) (TV)_ (qv)).
