Comments:
This is the first story of the Earth-1 period to feature the Joker. There is virtually no difference between the Joker of Earth-1 and Earth-2, so this will be considered the first appearance of the Earth-1 version. Batman has clearly encountered the Joker on previous occasions before this story. Appearances which take place chronologically prior to this story will be noted when they occur.

Synopsis:
When the Joker is paroled from prison, Batman keeps an eye on him, suspecting that the Clown Prince intends to return to crime. Batman follows his foe into a laboratory. By accident both Batman and the Joker are exposed to epsilon rays which cause them to exchange personalities.

While Robin seeks a cure for Batman's predicament, the Joker contacts the underworld. Since he has Batman's body he offers to expose the secret identity of the Caped Crusader for a million dollars. Batman, stuck in the Joker's own body, works to stop his foe. He befuddles police by catching crooks, then prevents the Joker from giving away his secret. Robin eventually comes through with a cure. Then the two foes are restored to their own bodies.
