Lt. Nyota Uhura: [singing] Oh, on the Starship Enterprise There's someone who's in Satan's guise, Whose devil's ears and devil's eyes Could rip your heart from you! At first his look could hypnotize, And then his touch would barbarize. His alien love could victimize... And rip your heart from you!

We know not what he'll do.

Captain James T. Kirk: The job is yours, Bones, flattery will get you nowhere.
Lt. Cmdr. Leonard 'Bones' McCoy, M.D.: What's going on here? Spock calls me to the bridge and then goes into some kind of poetry!
Captain James T. Kirk: [referring to the wounded Uhura] See to her, Doctor.
Mr. Spock: Once upon a midnight dreary while I pondered, weak and weary.
Charlie Evans: Very nice, Mr. Ears.
