Country bumpkin from the backwoods of Georgia joins the Air Force. Hilarity ensues. Not really. There are a few mildly funny moments here and there but for the most part this is a very labored comedy. In a role that inspired TV's Gomer Pyle, Griffith plays a fellow who has the IQ of a wild mushroom. He's supposed to be endearingly innocent, but it's an act that quickly wears thin, as the character is nothing more than a caricature. Although there is a lot of mugging going on, McCormick and Adams come off he best. There's a brief scene featuring Knotts that makes one want to turn this movie off and switch to a rerun of "The Andy Griffith Show." The film overstays its welcome by at least half an hour.
