I enjoyed Ebert's piece titled Creationism: Your Questions Answered. He uses creationist's own beliefs to satirically swat them upside the head. Really, it is funny... click over there and read it.
And yes, I know it is satire. Of course, I'm sure the drooling ID fools will try to use it as proof that another intelligent person embraces their stupidity. But one only needs to look briefly at Ebert's writings to understand his intelligence (that is, of a non-designed nature).
