The original Star Trek episode "Amok Time" introduced the Vulcan home world, and was in fact the first time viewers would see Vulcans interacting with one another. During the shooting of the episode, Leonard Nimoy felt that something was missing, that Vulcans should be seen as having a deep and complex culture. So, rather than shaking hands like Westerners, or bowing like Asians, Nimoy suggested to director Joseph Pevney that Vulcans should have their own distinctive greeting. "What do you have in mind?" asked Pevney. After some thought, Nimoy held his hand up in an unusual but now familiar gesture. Pevney liked the idea, and the rest is history.

What an incredible list of successful titles to his name. I did not realize that he directed so many. I wish to take the time to congratulate him posthumously for a his great job of directing!
Thanks Joe, you will be sorely missed. Thanks for sharing some of your blessed 96 years on earth with us.

"Life's tough. It's tougher if you're stupid." -- John Wayne
"In the counsels of Government, we must guard against the acquisition of unwarranted influence, whether sought or unsought, by the Military Industrial Complex. The potential for the disastrous rise of misplaced power exists, and will persist. We must never let the weight of this combination endanger our liberties or democratic processes. We should take nothing for granted. Only an alert and knowledgeable citizenry can compel the proper meshing of the huge industrial and military machinery of defense with our peaceful methods and goals so that security and liberty may prosper together." --Dright D. Eisenhower Farewell Address, 1961
"Frank O'Connor, the Irish writer, tells in one of his books how, as a boy, he and his friends would make their way across the countryside, and when they came to an orchard wall that seemed too high and too doubtful to try and too difficult to permit their voyage to continue, they took off their hats and tossed them over the wall--and then they had no choice but to follow them. This Nation has tossed its cap over the wall of space, and we have no choice but to follow it. Whatever the difficulties, they will be overcome. Whatever the hazards, they must be guarded against...."
" -- John F. Kennedy 21 November, 1963
