There Is No Cure for the Common Martian

T1, E3: Uncle Martin (Ray Walston) has trouble controlling his super-powers when he contacts the common cold, an affliction unknown on Mars. Fixing up a special pill to cure his malady, Martin leaves the powerful potion within reach of Tim (Bill Bixby), who accidentally consumes the pill and falls fast asleep just before he is to review an "outer space" exhibit at a local department store. Taking over Tim's assignment, Martin is appalled by the exhibit's glaring inaccuracies and pens a devastating article--thereby infuriating pompous store owner Trimble (played by former "Great Gildersleeve" Willard Waterman), who happens to be one of the biggest advertisers in Tim's newspaper!.
