Jed enrolls Jethro at an exclusive Beverly Hills elementary school. Millicent Schuyler-Potts, the proprietor of the school, is aghast when Jed and Jethro show up, convinced this is part of some ghastly hoax. After Jed says that banker Milburn Drysdale is his neighbor, she calls the banker. It turns out that Drysdale's bank holds the mortgage on the school. Schulyer-Potts suddenly warms to the charms of the Clampetts, even if it means accepting Jethro as a fifth grader.

Sonny Drysdale decides he needs to be Pygmalion to Elly's Galatea and remake her from a hillbilly into a woman of society, while Granny uses love charms to heat up their relationship.
