"Superman is a d*ck" is a concept originally conceived by the fine folks at Superdickery.com. In one of the earliest great things on the Internet, they compiled over 300 examples of Superman being selfish, needlessly cruel, and an all-around jerk in old comics from the '40s, '50s, and beyond.
Here's the absolute best of the "Superman is a d*ck" concept, out of over 300 examples. And yes, these are all real. A lot of them are just from a time in which they were selling Jimmy Olsen and Lois Lane comics by using a premise that doesn't actually apply to what is in the comic book itself. Some of these even say "this is not a cop-out" because most of them were. The contents of the inside of the comics most often had absolutely nothing to do with the covers. The covers where Superman is a d*ck were just ways for comic book companies and stores to entice readers to buy these probably horrible, yet now classic comic books.
