Superman is so manly that he has to disguise himself by costuming himself as a wimpy nerd. All other heroes are themselves until they put on their costume at which point they become a hero; Superman is so manly he has to put on a costume just to fit in with the regular folk.
Instead of horniness, sex appeal is another trait of manly men. Superman always has women fawning over him. Wonder Woman doesn't. Point Superman.
That should about tie it up, right?
Also, a debate I'd like to see: best now-obsolete gaming console. I'm thinking things like Atari, Colecovision, TI99-4A... all the other brands of gaming machine that died off in the console wars.
