Harleen Quinzel was a famous phone-in psychiatrist who hosted the show "Heart-to-Heart with Harley." She would talk to people about their love life, but was threatened by a mother when she told her daughter to go against the mother's wishes. The company threatened to pull the plug on Harley's show, but she had other plans. When Bruce Wayne arrived to talk about his charity, Harley attempted to humiliate him by bringing in one of his dates. All while the Joker, who was a fan of the show because of Harley's quirkiness and obvious fraudulence, called up under the name Mr. J, and got to voice his opinion. The company cut Harley's show, and she resigned to her apartment. The Joker, whose henchmen had recently been arrested, decided to make her his new assistant. He visited her house and she willingly followed him to his lair. She revealed that a nutcase like the Joker would be a perfect chance to restart her career and write a book. Joker didn't like the idea, but when he sicked his hyenas on Harley, she just yelled at them to sit. After a little "therapy time," Joker gave Harley a new outfit representing a . They spent a romantic bombing spree together, but were almost stopped by the Batman. In the morning, Harley was furious when she found out that another psychiatrist was planning a special show that would air at the time and channel when her valentine special would have. She was even angrier when she found out that the analysis was on her descent from fraudulent program into criminal madness. She and Joker crashed the show and Harley attempted to take revenge. Batman showed up and the building began to burn. Joker ran off with the hyenas, leaving Harley to her fate. She was saved, but realized that perhaps it wasn't a good idea to be with the Joker. But as she got into the police car, the officer sat on a whoopie cushion. He pulled it out to reveal that Mr. J had made his mark on Harley. She began laughing hysterically, perhaps destroying any possibility of her becoming sane ever again.
