Superdickery has galleries chronicling bizarre and hilarious Superman comic covers. One gallery has examples of Superman being, well, a dick. This one, where Superman ditches Lois Lane for Lana Lang because Lois has suddenly become old, is a great example. Another gallery collects covers that are just stupid, such as this.
Then there's the one where Lois discovers that Superman has a secret room containing a statue and giant photo of her and thinks that this is good news.
