I just looked up Shore Leave on Memory Alpha, the Star Trek Wiki, and read one of the most fantastic things that has ever passed in front of my eyes:
#
# A chained tiger is brought in to appear in the episode. While the tiger never directly interacts with any of the performers, William Shatner had originally hoped to wrestle it, but was convinced it would not be a wise decision.
Also it took a bit of googling because I had only vague recollections, but Voyager: Favorite Son. Also known as 'the remake of Spocks Brain but instead it's Ensign Kim and he nearly gets fucked to death'
Also the TOS episode with the Aliens who are exterminating each other because they are half black and half white (like mime make-up, like a line drawn down their middles) but on different sides,
and the crew of the Enterprise can't see the difference, though I guess it was at least noble at the time.
Also I have a vague memory of something to do with Voyager and dinosaurs? Am I making that up? I haven't watched any Star Trek except classic ToS epuisodes and films for about five years, and I gave away all my star trek novels (which are a VERY rich vein of stupid indeed), though I still have the technical manuals and an incredible boxed set of the entire blueprints for the Enterprise D. I think my parents bought me it for Christmas when I was a total star trek nut?
Actually thinking about it I have a book of production designs from ToS and the Star Trek Encyclopedia somewhere too.
