In tonight fox rerun showing the independent George, when Jery suggested Elaine to do things with George's fiancee, Kramer was quick to point out the world collapse theory. But I remember in another episode when Elaine wanted to move into Jerry's building and Jerry was reluctant and tried subtlely to keep her out, Kramer seemed to be totally clueless about Jerry's concern of Elaine in the same building with him.
