Bodyswap

Superboy saves a vacationing family from disaster as their car heads toward collision with a tree. He then proceeds to steal their car. Needless to say, Superboy is not quite himself. Later, Luthor confronts Lana in a parking building. He claims that he is not really Luthor, but Superboy. He explains that a scientist named Deland lured him to a lab promising information about his past, but instead of that, he found his mind transferred to Luthor's body. Lana doesn't believe him, and escapes ""Luthor"". That night, ""Superboy"" arrives at Lana's apartment wanting to take their relationship to a deeper level. Back at Deland's lab, the real Superboy is captured by Luthor and taken to prison so he can take Luthor's place in the electric chair. Lana breaks him free, and explains she knew the real Superboy would never come on to her like that. The two hatch a plan to get Luthor back in his rightful body.
