The Joker is the Batman's arch-nemesis, and is known as the Clown Prince of Crime in the crime-ridden city of Gotham. He thrives off his run-ins with the Bat, and strives to get his attention by doing crazy things in the city. He's the reason why Jason Todd died and eventually rose to become the Red Hood. He beat him, and then blew him up inside of the warehouse that he beat him in.

Mark Hamill is THE Joker, but John DiMaggio did such a fantastic job with his unique take on the clown. He has a pretty deep and somewhat gravelly voice. It's hard to describe his voice, so here's a link to a video filled with DiMaggio's Joker scenes: https://www.youtube.com/watch?v=VLwXcRq388M

The first line is said by Joker in the Killing Joke comic and animated movie. He says it in a low, but eerily calm voice. When you read this one over, try to read it as if you're smiling. If you can do it, add a bone chilling Joker laugh at the end of this line.

The second line is said in Batman: The Mask of the Phantasm. I'm looking for a surprised tone in your voice, but in a "finally a challenge" way.

The third line is in the scene that this is for. Start out with the low tone, but gradually reach a point of pitched excitement. https://www.youtube.com/watch?v=kgW7pBKcU4k&t=5s
