There's a site that's been around for awhile called Superdickery and it is one of the funniest sites I have ever been to. If you haven't been there before, you should check it out. It's basically dedicated to pointing out all the times that Superman is a total dick-- though they have branched out into pointing out the absurdities of any and all comic books.
Here's a few examples (the captions are theirs):
Damn, that's cold.
You know, if you're going to step out on your woman becauses he's inexplicably turned into an old woman, seems like the classy thing to do would be to not call attention to it...
I love this. Superboy would rather be pimping outhis ho there than save some little kid falling off a building.
Is this funny stuff or what? Go check out their site for more examples of Superdickery. If you're like me, you'll lose an hour or two.
