This is an interesting site, Identity Crisis: The Many Faces of the Man of Steel. It was put together by three American Studies students at the University of Virginia. I haven't been able to find a firm date, but it looks like it's from 2000. It's sort of an academic take on Superman in website form, including some cultural implications, historical studies, and whatnot. It seems light on content, to tell you the truth, but I haven't gotten through all of it yet.
This one's from last year, but it's funny nonetheless. At a dinner, Obama joked about the many comments at the time that cast him as Jesus. According to News.Scotsman.com (because why wouldn't I link to a Scottish paper for a story about Obama as Superman?):
"Contrary to the rumours you have heard, I was not born in a manger," Mr Obama said."I was actually born on Krypton and sent here by my father, Jor-el, to save the planet Earth."
