By James H. Burns: William Shatner and Leonard Nimoy competed in this episode of $20,000 Pyramid, available on YouTube.

What’s also interesting, is that if the late September, 1977 broadcast date is correct, this would have been taped when Shatner (and the rest of the Star Trek cast) was lined up for the new Trek teleseries that was set to begin filming later that Autumn — but which Nimoy had turned down. (I was ON those Enterprise sets at Paramount, in late November, just a week or two after the studio decided to go back to the initial idea, a Star Trek feature film.)
