The New Batman Adventures

Dr. Harleen Quinzel:
[narrating] It soon became clear to me the Joker, so often described as a raving, homicidal madman... was actually a tortured soul crying out for love and acceptance. A lost, injured child trying to make the world laugh at his antics. And there, as always, was the self-righteous Batman. Determined to make life miserable for my angel. Yes, I admit it. As unprofessional as it sounds, I had fallen in love with my patient. Pretty crazy, huh?

The Joker:
Not at all. As a dedicated career-oriented you woman, you felt the need to abstain from all amusement and fun. It's only natural you'd be attracted to a man who could make you laugh again.

Dr. Harleen Quinzel:
I knew you'd understand.

The Joker:
Anytime.
