I think "Hocus Pocus" is his best, followed by "Cat's Cradle". But how lucky are we to have so many good ones to pick from?

Thanks. Hocus Pocus slipped past me somehow. Now I have something to look forward to reading. (I liked Cat's Cradle too but it is also on the loopier end of Vonnegut's writing spectrum—but we need some more of that.)
