By one of those weird coincidences I had a character use the phrase "live long and prosper" in a chapter I posted at another site a couple of days ago - didn't have anything to do with Star Trek, except that the character was a fan of the show, but it's odd, I've never done so before.
He'll be missed; as Spock, as Paris (Mission Impossible), and as someone who seems to have done more than most to work for fair treatment of actors and actresses and other causes.
