Trivia / Batman: The Animated Series E41 "Joker's Wild"

• Throw It In!: The Joker's squee after explaining his plan to Batman wasn't in the script. Mark Hamill just sort of did it after reading his line, and the cast and crew were laughing so hard that they apparently took the rest of the day off. The next day, they went ahead and added an extra second of animation to include it.
