Commander Spock is the first officer of the U.S.S. Enterprise in the Star Trek: The Original Series of 1966, and overwhelmingly one of the franchise’s most universally known protagonists. He is famous for his pointed ears, angled eyebrows, and “Live Long and Prosper” split-finger salute which has become the unofficial greeting sign of Trekkies everywhere. With Spock’s trademark image so ingrained in his fans’ minds, it is hard to believe his iconic Vulcan ears were almost nixed due to the discomfort they caused the actor, Leonard Nimoy.
