Spock [After Kirk tries to drive an automobile]: Captain, you are an excellent starship commander. But as a taxi driver, you leave much to be desired.

Who are you callin' a babe?
I'm callin' you a babe.
YSYoung street urchin
You callin' me a babe?
Yeah, I'm callin'- [Urchin produces a knife and holds it up to Kirk's face] I'm calling you a babe, but it's nothing personal.
Are you afraid of cars?
Not at all, Captain. It's your driving that alarms me.

Suffer the death of thy neighbor, eh, Spock? You wouldn't wish that on us, would you?
It might have rendered your history a bit less bloody.
Spock, you're alive!
Obviously, Captain.

The only solution is what happened back then. A balance of power.
And if the Klingons give their side even more?
Then we arm our side with exactly that much more. A balance of power— the trickiest, most difficult, dirtiest game of them all, but the only one that preserves both sides.
