McCoy: "Jim, I think I liked him with a beard better. Gave him character. Of course almost any change would be a distinct improvement."
Kirk: "What worries me is the easy way his counterpart fit into that other universe. I always thought Spock was a bit of a pirate at heart."
Spock: "Indeed gentlemen. May I point out that I had an opportunity to observe your counterparts here quite closely. They were brutal, savage, unprincipled, uncivilized, treacherous -- in every way splendid examples of homo-sapiens, the very flower of humanity. I found them quite refreshing."
Kirk: "I'm not sure, but I think we've been insulted."
McCoy: "I'm sure."
I love this one just because I can totally hear McCoy in my head saying "I'm sure."
