What do you think are the best/worst ST:TOS series/lines, etc.? Here are some of mine. The "top 10" lists are in something of an arbitrary order after the top two or three.

Top 10 episodes:
1. Mirror, Mirror (can't beat Spock with a beard)
2. "Matt, where's your crew?"
"On the third planet."
3. Balance of Terror
4. Enterprise Incident
5. City on the Edge of Forever (not necessarily my favorite per se, but very well made, obviously)
6. "The M5 is perfect!"
7. "I am Nomad."
8. Return of the Archons
9. Let that be your last battlefield
10. "A phase 1 search assumes that the man wishes to be found?" (Court Martial)

Best lines:
1. "What hit? What attacked you?"
"They say there's no devil Jim, but there is... right out of Hell I saw it!
"Matt, where's your crew?"
"On the third planet."
"There is no third planet!"
"Don't you think I know that? There was, but not anymore! They called me, they begged me for help! 400 of them! I couldn't...I couldn't..."(Doomsday Machine)
2. "Mister Scott....Mister Scott" (Also Doomsday Machine)
3. "Captain - he's turned the engines off." (the one with the virus - the Naked Time, I think)
4. The speech by Kirk to mirror-spock at the end of Mirror, Mirror
5. The furious excitement that Dr. Daystrom goes into at the end of the computer epsiode (i.e. "your starships... toys to be crushed!" )
6. "We are creatures of duty, Captain."(Balance of Terror)
7. "This is the Atavachron."
"Interesting nomenclature. May I be permitted to..."
"Oh no, no sir. When you are ready, I will prepare you through the Atavachron." (I don't know, I just like that dialogue.)

Funniest scenes:
1. Fizzbin
2. Confusing Mudd's Androids (VERY close second)
3. Explaning Spock's ears in the city on the edge of forever

Favorite non-Enterprise characters:
1. Nomad
2. Harry Mudd
3. Romulan commander in Balance of Terror
4. Mr. Atoz (someone pointed out that this is "Mr. A to z" - makes sense for a librarian!- he also reminds me of the character Chang in the old movie Lost Horizon)
5. Dr. Daystrom
6.Bele and Lokai

I like most of the episodes. Anyone care to share your favorite/worst lists?
