I think I've found another reason why the Trope Namer has such an effective disguise. Because few would ever see them together or even individually much. To most of his town of Metropolis Clark Kent is just a name seen in newspaper articles, while Superman is just often seen at a distance by rubberneckers at disasters. Only those who spend any real time with both should have seen the similarity such as Lois Lane and Jimmy Olsen.

Judging from the Real Life entries down below, should this be classified as truth in television?
