Funny. He wants you to laugh. [ADDED: Hope the link works now. MORE: Actually, the Times is making it really hard to link to the video. Go here and then look for the video in the sidebar.]
AND: Here's Buchwald's last column, written to be published after his death. He has surprisingly little to say about death, perhaps nothing at all. He says a little something about life and about dying. He made a decision to forgo dialysis, and he says that decision was his and it was "healthy." He doesn't expound, and I suppose he means for us to find humor of this use of the word "healthy" when the decision would kill him. Not having dialysis was utterly unhealthy, but the decision could still be healthy. A decision is something that occurs in your mind.
