Well, tonight I was reading some old comics and found out that this was actually a swipe from an earlier Jimmy Olsen tale:
Eventually we learn it was all a trick by Perry to test them as mentioned above for their suitability as foreign correspondents:
But perhaps most surprising of all is that both stories turn out to be lead-ins to future tales. I discussed the rather ridiculous Lois Lane, Foreign Correspondent story, but Jimmy had his own follow up:
Jimmy's story is a little better. He and Clark travel to Hoxana, to find out if the new king is going to be a tyrant or a good guy. Jimmy quickly finds out that it's the former:
This swipe is a little quicker than some of the other ones Weisinger did--Lois Lane #36 was published in October 1962, a little less than five years after Jimmy Olsen #25 (December 1957). But it is certainly noteworthy because of the lead-in nature of both stories to later tales.
