It seems that somehow Julius Schwartz of Earth-Prime is having a problem dealing with his birthday. So somehow, his persona is suffled to Earth-1 where it takes up residence in that continuity's Julius Schwartz. From begining to end this story is very hard to follow, then be able to digest. I guess the only thing that possibly might make this story worth-while is the fact that for a brief moment (which no one will remember), all the creators get to meet Superman when he return Julius Schwartz to Earth-Prime.
