Synopsis
Several subplots are woven into this episode. The Beverly Hills police look askance at Granny's backyard still and Elly May's menagerie of "critters." The Clampetts decide to pay a visit to their Beverly Hills neighbors, unaware that its Halloween. And back in the Ozarks, Cousin Pearl has set her cap for oil executive Mr. Brewster. The scene in which the terrified suburbanite sees Jethro's "mask" is a riot.
