The New York Times has up a video obit for Art Buchwald, complete with him announcing his own death in a segment that he filmed for that inevitable event. [CAUTION: Plays music as soon as the page loads.]
He also left a final column to be published after his death. You can read it here.
Buchwald was a very funny man…and very fair. I can't find the quote but he once said something like, "I can't afford to play favorites. When you have to fill as many columns as I do a year, you need to go after everyone." Indeed.
