After several new Gotham-themed websites launched over the holiday weekend, it appears that the Joker is getting in on the fun as well. He’s made some modifications to the Gotham Times at a new site, The Ha Ha Ha Times, and also has a new personality profile quiz up on his Why So Serious? site.
Also, Geekanerd points out that there are quite a few references to Gotham Central in the Gotham Times.
