On his first day, Clark's taxi is commandeered by a police officer to chase after a group of mobsters who kidnapped Perry White himself. As Superman, he stops the mobsters' car, saving both Perry and the police officer. Clark gives Perry a ride back to the Daily Planet building and reminds him of the reporter's job he wants, but Perry doesn't remember him, as he's too occupied with exposing the city's powerful crime syndicate. The next day, Clark applies for a job at the Metropolis Police Department and is given a special beat despite being thought to have bad eyesight. The next day, Clark discovers his beat is ticket collector at the City Aquarium. While there, a newspaper photographer is thrown into an octopus tank, and Clark is forced to jump in while still wearing his officer's uniform to save him, but he uses a quickly constructed dummy Clark to preserve his secret identity. The next day, Clark loses his police job because of his supposedly poor eyesight and becomes a door-to-door vacuum salesman. He visits Perry at his home to remind him of his promise, only to discover Perry is being held at gunpoint by a mobster, and he rescues Perry as Superman after creating a smokescreen with the vacuum cleaner. Superman uses chemicals to tag every mobster in town, then uses the mixture of those chemicals together to track down the location of the King of the Rackets, who has kidnapped Perry White. Clark writes up the story of the capture and sends it in while Perry is recuperating, and the Daily Planet publishes it. Perry finally remembers meeting Clark when he was a boy and grants him a job interview.

June 29-30: Perry White interviews Clark Kent and introduces him to staff reporter Lois Lane. After Clark claims to know every major Daily Planet headline for the past 30 years, Perry has him prove it, and Clark recites 500 headlines. After Lois asks Perry to give Clark a chance, Perry has Clark do a story about an old gorilla at the zoo in order to get rid of him. Clark uses a gorilla outfit to stage a mock battle between a younger gorilla with the old one in order to get a rousing story. But Perry still refuses to hire Clark and has him cover a carnival opening that night. When two kids are stranded at the top of a Ferris wheel, Superman secretly fixes it and then sits on another gondola behind the kids as Clark in order to write a first-hand account. Perry still won't hire him, thinking he was goofing off on a Ferris wheel, but Lois persuades him again to give Clark one last chance. So Perry asks Clark to get a picture of Superman with a piece of kryptonite captured from the Anti-Superman Gang to find out if it really affects him, but when he opens the lead-lined box, Clark faints from the radiation. He manages to cause his stomach to rumble so that Perry and Lois think he's starving for lack of money, and they take him to a restaurant, where Perry promises him a job if he can get the picture. Getting rid of the kryptonite and replacing it with a fake lookalike, Superman takes a picture of himself at super-speed being unaffected by it, causing Perry and Lois to think the kryptonite is fake. Perry tells Clark to visit him the next day. Note: Clark Kent has met Lois Lane at least three times earlier, twice when they were teenagers, and once a few months earlier, just before Lois began working for the Daily Planet.
