Great joke from Leno last night:

[Rita] is like the ninth hurricane this season... You know, maybe this wasn't such a good time to take God out of the Pledge of Allegiance.

For interest's sake, Jon Stewart made almost the exact opposite (and equally-funny) joke a couple of weeks ago, after Bush announced the National Day of Prayer (which I will paraphrase, because I don't quite remember it):

National Day of Prayer? Correct me if I'm wrong, but I'm pretty sure Katrina was an act of... God. Maybe now's not the time for praise. Maybe now's the time for... shunning.
