Synopsis:
Inventor, Professor Potter, demonstrates his new evolution machine on Jimmy Olsen. The machine gives Jimmy a super-brain for 12 hours. During that time, Jimmy orders Superman to move several large objects around the Earth. If Superman refuses, he threatens to expose his secret identity. Superman complies, and eventually Jimmy's super-brain wears off. Jimmy has no memories of his evolved experience, but he left a note for Superman. The note explains that Jimmy was able to calculate the balance of the Earth was off. By ordering Superman to move large objects, the balance was restored, saving Earth from future destruction.
