I think this Onion article about Evangelical Scientists proposing that "Intelligent Falling Theory" be given "equal time" in Kansas schools gets at the heart of the matter with regard to misunderstanding how science is supposed to work. I especially liked this bit:
Proponents of Intelligent Falling assert that the different theories used by secular physicists to explain gravity are not internally consistent. Even critics of Intelligent Falling admit that Einstein's ideas about gravity are mathematically irreconcilable with quantum mechanics. This fact, Intelligent Falling proponents say, proves that gravity is a theory in crisis.
Update: Yes, I've heard of Pastafarianism, too, but I think the Intelligent Falling article is a more insightful approach. Well, I suppose they attack different aspects of Creationism. Intelligent Falling attacks the Creationist argument that evolution is "just a theory", when of course all science is "just a theory". The Flying Spaghetti Monster thing attacks the "equal time" argument, because of course of course if you want equal time, why not give ALL religions equal time?
I guess the thing that makes me uncomfortable with the Flying Spaghetti Monster thing is that it unnecessarily mocks religion in general to make its point. There's no need to invent a new deity, when you could easily point to the varying Creation stories of several other major religions and ask why we don't include those in "equal time" as well. Nonetheless, this is a pretty impressive painting.
