This show is about a dumb but big-hearted guy, who joins the US Marine Corps.  He looks up to Sergeant Carter more than anyone, but Carter is constantly annoyed by the do-good truth-telling Gomer.  The cast includes Jim Nabors as Gomer Pyle, and that's the only one I can think of off the top of my head right now.  The show was originally a spin-off of the Andy Griffith Show, which featured Gomer Pyle as a mechanic.
