"Believe it or not, I was not Gene Roddenberry’s first choice to play Spock. So, who was the first choice, the actor who turned down the role? George “Goober” Lindsey. True." -Leonard Nimoy

In the same TVLand series of 'bumpers', Nimoy claims 'Live long and prosper' was originally supposed to be 'Take it easy'. In another, Nimoy uses a tricorder to scan for cheese.

Too bad, it's a great story.
