Favourite Star Trek TOS episodes?

[such_heights]

It's a very exciting time here at at Purple Heights Manor - after gradually making our way through Buffy over the past year, it is nearly time for me to start showing purplefringe Star Trek. \o/

I want to start at the beginning, but I'm not sure we're going to want to watch the whole of the original series (though there's a distinct possibility we will be compelled to watch Spock's Brain, with alcohol). As I haven't watched the whole series myself, I come to the internet for aid.

So! Which TOS episodes are your favourites? Which ones do you rate as the most significant in pop culture or fandom? My list from my limited viewing would include:

Where No Man Has Gone Before
The Naked Time
The Enemy Within
Balance of Terror
Arena
The City of the Edge of Forever
Amok Time
Mirror, Mirror
The Trouble With Tribbles
Turnabout Intruder

What am I missing?

Basically all of it.

The Cage (original pilot, and not the version that got redone as an episode) is important, it's a very mindfucky plot (for the 60s).

Definitely Devil in the Dark.

FTWIHAIHTTS is all right, but largely it's an example of 'plots that would have been stretched over several episodes now being dumped in your lap with no setup.'

The Empath, for the OT3 bits.

Bread & Circuses, mmm, yes, Bones/Spock. Plus the only reference you get in TOS to Christianity even possibly still being a thing.

Court Martial - Jim is framed for murder, Bones gets to use his space psychology degree, Spock gets to use a microphone, and Jim tears his shirt again.

If you watch Trouble with Tribbles, you must immediately follow it up with Trials and Tribbleations. This is a requirement.
