From The Adventures of Batman & Robin (formerly Batman: The Animated Series):
Harley Quinn (Arleen Sorkin) has been declared sane and released from Arkham Asylum. However, attempting to go shopping with her pet hyenas in tow leads to nothing but chaos.
Marilu Henner (ex-Taxi) and Franklin Cover (ex-The Jeffersons) guest star in "Harley's Holiday".
Now, if WB can get Harley's creator, Paul Dini, back from Marvel, maybe a Harley solo series is in order......
