The Joker

I'm aware that the Joker is a character who's open to interpretation - he tends to vary wildly depending on who's writing him.  Still, the source material that I'm taking him from seems to be pretty consistent, (seeing as it's just two games and their tie-in comics) so feel free to let me know what I'm doing wrong, or give me tips, or whatever you feel like posting!  IP address logging is off, and anonymous comments are screened
