That was before my time, but I did fall in love with Star Trek TOS in the 70s, watching them in syndication on UHF! The UHF channels in Philly were 17, 29, and 48...and IIRC, Star Trek was on Channel 29. (But it might've bounced around over the years.)
The Man Trap's salt creature scared the crap outta me! lol Great episode!
My favorite episode was Patterns of Force, the Nazi episode. Don't hate me, I was just a little kid, but I loved Nazis when I was young. My number one favorite show was Hogan's Heroes! Up until about age 10, I thought the Nazis were the funniest, coolest guys around! Of course, I knew nothing (pardon the Sgt. Schultz pun) of the atrocities committed by the Third Reich. Today, the only good thing I can say about the Nazis is that they had the coolest, most badass military uniforms of all time. (But I still love Hogan's Heroes!)
With no internet, no VCR, no DVR...I just had to wait eagerly for the next time they'd air Patterns of Force--and many other TOS favorites of mine, like The Menagerie (I was fascinated--pardon the Spock pun--by Captain Pike in that futuristic wheelchair), Arena (the Gorn captain was scary as Hell), Amok Time (the epic battle between Kirk and Spock!), A Private Little War (loved and terrified by the Mugatu!), Assignment: Earth (loved seeing the crew go back in time on Earth!), Catspaw (not a great episode today, but as a kid, I was thrilled by a huge black cat!), and Who Mourns For Adonais (I wanted to be like Apollo, to be able to speak with a loud echo to my voice, and grow to 50' tall! i'm so stoked STC did a sequel to this episode, and that they got Michael Forest to reprise his role of Apollo, which he absolutely nailed! i loved Steve Reeves movies, and Apollo reminded me of him.).
I loved almost all of the TOS episodes--minus The Squire of Gothos, and the couple of episodes with bratty kids--but the above are some of the episodes that made the biggest impression on me. Oh, I suppose I have to add The Corbomite Maneuver to the list of favorite eps from my youth, as I was fascinated by the little boy (Clint Howard) running that ship. lol
Today, however, I'd have to rank my favorite episodes this way:
1) Mirror, Mirror
2) The City on the Edge of Forever
3) Space Seed
4) Amok Time
5) A Private Little War (Nona!)
6) Balance of Terror
7) Patterns of Force
8) Arena
9) Wink of an Eye
10) Turnabout Intruder (I know a lot of fans hate this episode, but I love it!)
Happy 50th, Star Trek! Live long and prosper.
