||Without meaning to, Jimmy agrees to be a test subject for a week for a race of people from the planet Jupiter. As part of the experiment, he gains the ability to read people's minds, but he is also turned into a green, scaly Jovian. He uses his new abilities to compete for the Newsman of the Year award, though he wraps himself in bandages to cover his appearance. Between tracking down scoops, Jimmy casually reads Clark Kent's mind and "hears" Clark think that he is Superman. When his rival Vince Regan sees Jimmy without his bandages, he plans to expose him at the award ceremony. But luckily for Jimmy a Jovian week is equivalent to 5 Earth days, and when his bandages are removed at the ceremony Jimmy has reverted to his old self. The Jovians declare the experiment a success and help Superman preserve his secret identity.
