Jacques Bergerac guest stars as King Alexander, the exiled monarch of Sabalia, one of those tiny kingdoms that exists only in the minds of sitcom writers. Hoping to increase the Clampetts' bank account, Mr. Drysdale promotes a romance between Alexander and Elly May. There's only one problem: the king is flat broke. Edward Ashley appears as a yachtsman, while Victoria Carroll is seen as Doreen. "His Royal Highness" made its original CBS appearance on March 8, 1967. ~ Hal Erickson, Rovi
