Dr. Joan Leland, Harley and others in “Harley's Holiday”

You've made wonderful progress, Harley. You've passed your competency hearing, and tomorrow, you will be released, mentally sane and sound.

Harley

Wheee! Wahoo! Whoopee! Yay! Yay! Yay! Uh... I mean thank you, Dr. Leland.

That's ok. You have every reason to be proud of yourself.

Scarecrow

[offscreen] Unhand me!

I just wish the other inmates could make your sort of progress.

Scarecrow

I am the Master of Fear! The Lord of Despair! Cower before me in witless terror!

Harley

Hi, Professor Crane!

Scarecrow

Good evening, child. [To Batman and Robin] Worship me, you fools! Worship me! Scream hosannas of anguish to Scarecrow, the all-terrible God of Fear!

Robin

I think he's getting better.
