Kal-El should be Clark Kent instead of Superman - Sure, it's all fictional, so could be argued to suit any point, but Superman was the nickname given him by the Daily Planet because they didn't know his identity, like Boston Strangler or Jack the Ripper. His pseudonym was actually Clark Jerome Kent.
It says "the name they are more commonly known by." I'd bet anything that if you ask 100 people who Kal-El is (assuming they have any idea), many more will say Superman than will say Clark Kent.
Originally the S stood for Superman however that was retconned when the writers decided it's a bit egotistical for a supposedly humble hero to proclaim himself as a "Superman". It's usually now the case that the S is his family's coat of arms which coincidentally looks a bit like an S, which then inspires someone to give him a nickname beginning with that letter.
Nick Cage is still making movies so he can afford to eject his son into space. There just can't be any other reason at this point. In the implausible world of Nick Cage, it's the only plausible explanation.
Yeah, I saw William Jefferson Blythe and actually thought, "hmm, that's weird, Bill Clinton's name is William Jefferson," but didn't think to try it because I had no idea his last name had ever been Blythe.
It's reported that W.J. Blythe Jr., a traveling salesman, was still legally married to another woman when he married Clinton's mother, but she had no idea of his lengthy and "interesting" marital history. Blythe died near Sikeston, MO, which is coincidentally about 80 miles north of Blytheville, AR.
9/20 - tough quiz! I did get Temujin because my undergrad is in Chinese history and guessed correct on Cher because most names that end in -ian or -yan are Armenian, which I know she is.
Maybe in the most recent reboots, but the vast majority of the other material out there warrants keeping that ? right where currently it is. DC has been all over the map with Superman except for being able to make him a compelling and complex character. That's just not in his Kryptonian DNA no matter how his story gets spun.
You'll be surprised who some of these are!
