Only tangently related to the discussion...
Something dawned upon me so I checked the initial airdate of this episode which was March 8, 1968. Oddly enough, Kubrick's magnum opus, "2001: A Space Odyssey" debuted almost a month later, April 6, 1968.
Hey! Kubrick stole from Trek!!!
Okay, even as grade school humor, that was lame. Still, you gotta' chuckle at the timing.
We now return this thread to its normal (abnormal?) discussion.
