Guest star Henry Jones plays a flamboyant eccentric who imagines himself to be King Arthur. Wearing full armor, "Arthur" rescues Adam Cartwright from stagecoach bandits. When Adam is accused of masterminding the holdup, he finds that no one believes his wild yarn about a "knight in shining armor"-and before long, virtually everyone in the cast is convinced that Adam has gone off the deep end. Also appearing are Robert Sorrells as Cyril, Charles Watts as Sheriff Munsey, Zeme North as Phoebe and Rodolfo Acosta as Juan. Written by Robert V. Barron, "A Knight to Remember" was originally shown on December 20, 1964. ~ Hal Erickson, Rovi
