I am, incidentally, Honorary President of the American Humanist Association,
 having succeeded the late, great science fiction writer Isaac Asimov in that
 totally functionless capacity. We had a memorial service for Isaac a few years
 back, and I spoke and said at one point, 'Isaac is up in heaven now.' It was
 the funniest thing I could have said to an audience of humanists. I rolled them
 in the aisles. It was several minutes before order could be restored. And if I
 should ever die, God forbid, I hope you will say, 'Kurt is up in heaven now.'
 Thatâ??s my favorite joke.
