In the conclusion of a two-part episode, greedy banker Drysdale is laboring under yet another misapprehension. This time, Drysdale has convinced himself that Hooterville aviation-service proprietor Howard Hewes (Guy Raymond) is actually billionaire recluse Howard Hughes. Anxiously, Drysdale tries to negotiate a merger between the Clampetts and Hewes -- whose personal "fortune" amounts to a little less than zero. "The Clampett-Hewes Empire" first aired on January 7, 1970. ~ Hal Erickson, All Movie Guide
