"Marsha, Queen Of Diamonds"
Marsha returns to Gotham City and quickly takes control of Gordon and O'Hara with her love darts. She then leaves them in cages in her basement, where they start barking at each other for Marsha's affections. Gordon's disappearance brings Batman and Robin to Marsha's lair.
Batman is able to resist the drug using his supreme powers of concentration, but Robin is not so lucky. His inexperience allows Marsha to take advantage of him, and he is soon imprisoned with Marsha's other slaves!
While Batman mentally fights off the effects of Marsha's drug, he loses control temporarily and starts chanting her name lustily.
Will Batman have to put a ladies' room in the Batcave?
