When Is Dark Humor Too Dark?

This Sunday is the tenth anniversary of 9/11. And the day after is the tenth anniversary of the first 9/11 joke. This week we talk about about black comedy and gallows humor. Is there any value in joking about things that will upset some people. Are there guidelines about what you can joke about and when. And if so who decides what they are? And isn't a comedian honor bound to break those rules? So what would be the point of them if they existed? I guess what I'm trying to say is Never Forget...about this podcast.
