Vulcan truth: It will be inconvenient for YOU not me

Malakon describing Spock: Note the sinister eyes and the malformed ears: definitely an inferior race. Note the wide forehead denoting stupidity and the dull look of a trapped animal.

Spock: On my planet "to rest" is to rest, to cease using energy. To me it is quite illogical to run up and down on green grass using energy instead of saving it. Nowhere am I so desperately needed as among a shipload of illogical humans.

Kirk: Very good, Spock. We may make a human of you yet.
Spock: I hope not!
