I love it too! I have a problem with the galactically stupid Lois, and this was certainly a delicious new way of looking at things! It's funny, you know, that Superman's disguise is so ridiculously flimsy, but for all of that it has always fooled everyone. And yet, it was as if Lois's "approval" of his disguise, and her refusal to see through it, was necessary for everyone else to be fooled by it. Here we have a situation where Lois actually knows what she is doing: not only is she pretending to be taken in by Clark's disguise, but by pretending to be fooled by it she makes everyone else believe that Superman and Clark Kent are two different persons.
Fascinating and very sweet!
