How Can We Effectively Satirize Faith?

I saw this article at Friendly Atheist. It makes a point that satire is an effective way to point out flaws in an argument while not angering those who support it, because they are too busy laughing to see they just got owned. The article references Jon Stewart's Beck satire. I'll post it here because
a. if you haven't seen it, you should.
b. if you have seen it, watch it again! it is funny!
c. we all need laughs
