The Joker - Batman: The Animated Series:
How can you not love Mark Hamill's Joker? He's an icon. The Joker is nearly as famous and revered as Batman himself. Yes, he's sadistic, but he's also hilarious. Over the years, he's delivered priceless one-liners and even a song or two. Our personal favorite? "Jingle bells, Batman smells, Robin laid an egg, the Batmobile lost a wheel, and the Joker got away! Oh Joker, thanks for the childhood memories.
