So the thing about Superdickery is that it's a site that relies on the assumption (usually well-founded) that the reader has never actually read the comic in question. It assumes that the typical reader has neither the time nor the inclination to actually go read terrible Silver Age comic books and find out the answers to the dramatic questions posed on the front cover - what is the actual mystery of Superman's Mystery Song? Superdickery is aimed at the reader who will never know or care.
Superdickery, in other words, is not a site that is aimed at someone like me. Do you dare to follow along as I reveal the terrible secret of..
Superman's Mystery Song?!As we begin our story, Clark is going to Lois's apartment to help her move some books. On seeing the inside of her apartment, we find out...

Lois is a Pat Boone fan. And why shouldn't she be?

These guys like Pat Boone.

Even Clark likes Pat Boone. Do you like Pat Boone?
Then some inexplicable nonsense happens.

With that out of the way, we find out Pat Boone is visiting the Daily Planet! And more than that..

He overhears Lois singing a song and asks her to perform with him! What a swell guy. No wonder everyone likes him.

Clark's a newspaperman, so he's got to be good at writing things. That naturally includes song lyrics, right?

Well, maybe not. (Click the image for a bigger version if you can't read the lyrics.)
Kids! Can YOU figure out the secret of -
Superman's Mystery Song?!While you're working on that, Superman spends a couple of pages on more inexplicable nonsense.

Why would Superman prevent Pat and Lois from performing their song? Because it takes him time to work out a real solution to his problem! Which as it turns out..

Is that he dreams in acrostics. As you probably noticed.
So Superman doesn't actually prevent Lois from performing with Pat Boone - he just stalls them in really weird ways while he comes up with new lyrics for them. It's entirely a problem of his own creation, but who among us hasn't accidentally revealed his secret identity by writing terrible song lyrics in their dreams now and then?
This is my problem with Superdickery. Silver Age Superman isn't an asshole, he's
batshit insane. And so is the universe he lives in.
