Dr. Bombay's new pills have a strange side effect on Uncle Arthur. His "power system" on the fritz, Arthur began transforming into whomever and whatever he happens to be thinking about -- a pony, a demon, a Native American, and finally Superman. Somehow or other, Arthur's out-of-control morphing saves Darrin and Larry's latest advertising campaign. Written by Ed Jurist, "Super Arthur" made its first network appearance on February 5, 1970. ~ Hal Erickson, Rovi
