One of my favorite aspects of stories from the Silver Age of Comics is the way people - especially Superman - make these weird, non-sequitur intuitive leaps based on the most tenuous reasoning.

Well, duh, Superman; what else could it possibly mean?
Of course, in the modern era of comics, Lois dressing up as Batwoman would lead to the assumption that she's decided to play for the other team, and her "secret romance" would probably be with Lana Lang.
(Hey, you didn't really think that Superman was at the heart of their "rivalry," did you? That much passion can only have one source.)
