Superman recalls his college days, particularly the professor who tried to scientifically prove that Clark Kent was Superboy. Professor Maxwell had Clark take a polygraph and answer if he was Superboy; Clark passed the test when he replied "No" because he now regarded himself as Superman.; Lois falls off a ledge while trying to get a scoop as a reporter. She is knocked unconscious and taken to the hospital by Superman, where Lois dreams she and Clark gain super-powers and become Power-Girl and Power-Man. Clark still possesses a timid personality and is inferior to the leadership of Lois/Power-Girl.; When Superman is exposed to the "strange power" from the explosion of an alien space ship, he loses his powers but gains the ability to create a miniature version of himself to carry out his super-duties. Eventually the "super-imp" becomes more popular than Superman, who begins to harbor resentment and sends the midget duplicate on a potentially fatal mission involving kryptonite. Destroyed by the kryptonite, the midget seems to sacrifice itself so that Supes can return to normal.
