Mr. Mxyzptlk returns to Metropolis and plays a practical joke on Jimmy by creating three duplicates of the boy reporter. The four Olsens create confusion for everyone, until Jimmy finally punches himself in the nose. When he bleeds, Superman realizes that he is the real Jimmy. Jimmy and Superman then trick Mxyzptlk into saying his name backwards, returning him to his home dimension, and destroying the duplicate Olsens.
