Golden Age? He would beat the everloving shit out of you, and keep doing it as often as he thought it was necessary.
Silver Age? He would probably pull some elaborate and horrifying prank on you to "teach you a lesson," which would no doubt leave you scarred for life.
Modern Age? I don't know, I don't think he's actually all that scary. I mean, Batman would definitely mess you up. Probably Wonder Woman, too. But Superman? I just don't know.
