You act so shocked but the fact of the matter is that it really is quite normal. Think of every comedy movie, stand-up special, or roast you've ever seen. A lot of the times when someone laughed, it was because someone made a joke about something horrible. AIDS, Cancer, Poverty, 9/11, who gives a f***? It's all fair game as far as I'm concerned. If that's a problem, then it's a problem I don't want to get fixed.
