Superman finds himself compelled to gather souvenirs from outer space and bring them to a time capsule being set up outside of the Metropolis Museum. Unable to figure out what force is posessing him, Superman is powerless. Lois Lane figures out the mystery first, though. Each trophy he brings back is from a planet whose first letter forms a letter in Superman's name. Saturn, Uranus, Pluto, Earth, Rhea, Ariel, Neptune. Unaware of his compulsion, Clark's coworkers at the Daily Planet think that Superman collected the trophies out of conceitedness. Clark is unable to defend Superman's reputation.
