Star Trek TOS was my favorite show as a kid and it still is as a 59 year old geek.
Oh man. It sounds stupid but TOS was my life growing up. I was TOS obsessed. I watched every episode over and over and over every evening at 6pm on one of the UHF stations. Had every line of every episode memorized almost. I was a bit OCD as a kid.

We had a weird setup. We had two local competing UHF channels and I guess they were both too small to afford the TOS license so I guess they split the cost and half the year TOS was on one channel half the other. When they switched they have a marathon and run every episode in order. That was my yearly Mecca pilgrimage and I'd stay up all night. My parents just rolled their eyes and let me slide once a year. LoL.
For a certain cohort of our Gen-X population, TOS was formative. It's a set of mythology that we all pretty much share. I think Star Wars and TOS were to Gen-X'ers like what Homer's Iliad and Odyssey were to the Ancient Greeks.

Yes, I begged for the Star Trek Technical Manual for my birthday or Xmas for years.
