Superman question
This is an old rumour I'm hoping some Superman expert can help with... I heard somewhere once that there was an old Superman story where he tries to punch Luthor, Luthor dodges, and Superman's fist swings right back up and punches Supe's own face. End result Superman knocks himself out.
The explanation was that Superman was so powerful that writers had to come up with more and more ridiculous ways for people like Luthor to be able to challenge him.
I don't know what decade it was supposed to be from. Is there any truth to this story at all?
