Grandpa and Luke are left with an unproductive hired helper when Pepino apparently inherits a valuable Arizona estate. He warms up his romance with an old girlfriend and brings a flood of salesmen to his doorstep.

Afraid that Grandpa will disapprove, Luke pretends that the girl veterinarian secretly treating their ailing cow is one of his new girlfriends. When Grandpa learns that Luke's ""romance"" is actually only trying to cure Agnes, the sick cow, he explodes, ordering the girl off his property.

Luke lands the enjoyable job of teaching calisthenics at a ladies' health club. Grandpa decides that Luke's presence there may attract some business for the McCoy roadside fruit stand. Grandpa then surreptitiously tempts the dieting health club enrollees with a variety of tasty fruit products, thus undermining the efforts of unsuspecting Luke.

Grandpa and George take turns at playing Cupid when their respective farmhands, Pepino and Pedro, find themselves competing for the same girl. Grandpa steps into the romantic triangle because it turns out that Pepino's working efficiency suffers as he loses favor with his girlfriend, Chiquita.

Luke feels he has discovered a new source of income when he reports the gossip he overhears at the laundromat to the reporter of the local newspaper and is paid for the items. He runs into trouble with Pat Clemens, who runs a local gas station, when he reports that Pat is getting married.

Luke gets a hair-raising ride in an airplane that leaves him dizzy when he tangles with a crop duster over the affections of a wealthy girl from Texas, and winds up on the short end.

Uncle Rightly McCoy starts courting Flora, hoping she will finance his musical milker. When Luke informs George that Uncle Rightly is only interested in Flora's money, they decide to step in and break up the romance. Their scheme doesn't quite work out as they had planned.
