Kandor, the shrunken Kryptonian city that Superman keeps in a jar (ah...I love foreshadowing)
A crystal ball which is really a two-way TV set that can contact Superman
Superman leaves Lois all alone to look around while he goes to some appointements (if I know Superman, it probably has something to do with orphans. While looking at Kandor klutzy Lois knocks the jar over and it cracks open. So, obviously a devious criminal, Zak-Kul breaks out. He is then able to re-enlarge himself (he musta used one of those emails I'm always getting) and use an "Electronic Plastic Surgery" machine with a Superman button to make him look just like our hero. He then takes the clothes off of a Superman mannequin to complete the disguise.Lois realizes pretty quickly that Zak-Kul is not Superman thanks to a message from the real Supes on the crystal ball. The criminal immediately tells Lois his plans to shrink Superman. He then cuts off another Superman mannequin's head that falls and knocks her out. When she comes to she is able to get the shrinker/enlarger and is faced with two Supermen. You would think at this point Lois would be happy about having another option for marriage, but no, she has to figure out which is the real Superman.
She asks one simple question about some lame criminal and has made a decision, so she blasts a Superman with the shrink-ray. Turns out it was the real Superman. You see, he faked not knowing about a criminal for fear that if Zak-Kul were found out he would start a Super-Fight and wreck his temple to himself. Superman is then shoved back into the jar using tweezers. Zak-Kul, for no apparant reason decideds to assume Superman's identity and begins to save people, and even asks Lois to marry him. Score!So, they live happily ever after. Well, no, you see, Lois still wants to know his secret identity. Fake-Superman gets nervous, so he decides to kill Lois by making her drive off of a cliff. And then...Superman swoops in a saves her. You see, he shrunk himself down so small that he fit between the atoms of the jar (FYI criminals, now you can all get out of Kandor!). He then re-embiggened himself and rescued Lois, who promply rips up the marriage license that she carried with her at all times. Phew, another marriage averted!
