I'm probably going to hell for even reading this, let alone posting a link to it. Atheists/Agnostics and Christians that can laugh at some of the less desirable aspects of their faith will get a good chuckle out of it. If you are of the persuasion that thinks that laughing at any aspect of religion == laughing at God, then you'll probably be somewhere between extremely and totally offended.
