There is a quote that has been floating around for years now that reads: "never stop having fun. Because the moment you do is the moment life isn't worth living anymore." With his famous mantra of "Why so serious" it's fairly obvious that the Joker lives by these words. The best way to approach life, no matter what your aim happens to be, is to have fun with it. Never, ever underestimate the importance of having fun. So we see the Joker always laughing and cracking jokes, and trying to make others smile. The fact that they dont get his brand of humor is not his problem; hes too busy having fun...What other life lessons have you learned from the Joker over the years?
