the trouble with tribbles is THE bitchiest episode of star trek
"Extremely little, ensign"
"Is the rest of your history that faulty, ensign?"
"You'll... try to explain? You'd better be prepared to do more than that."
Spock talking at length about quadrotriticale because Baris dared to assume he's uneducated in agriculture. Kirk letting him go on for a while just for the hell of it.
"I have never questioned the orders or the intelligence of any representative of the Federation. ... :) Until now :)."
Every single silent glance between Kirk and Spock throughout the full runtime.
"I was not aware, Mr. Baris, that twelve Klingons constitutes a swarm."
"But you've got, uh... eleven?" "You noticed that, huh?"
The bartender pointedly pulling fourteen tribbles one by one out from under the counter.
Spock and McCoy's entire talk in medical, but this especially "Spock, I don't know too much about these little tribbles yet, but there is one thing that I have discovered" "What is that, doctor?" "I like them. Better than I like you" "Doctor?" "Yes?" "They do, indeed, have one redeeming characteristic" "What's that?" "They do not talk too much"
"On the contrary, sir. I think of this project as very important. It is you I take lightly."
"You heard me!" "Oh I heard you"
"Now, if you'll excuse me, I have a ship to tend to. Au revoir."
"Mr. Baris, I'll hold you in irons if you don't shut up!"
"Hm. Now he tells me."
"Mr. Baris, they like you! Well, there's no accounting for taste."
