Scotty: Do you mind a little advice? Starfleet captains are like children. They want everything right now and they want it their way. But the secret is to give them only what they need, not what they want.
Geordi: Yeah, well, I told the Captain I'd have this analysis done in an hour.
Scotty: How long would it really take?
Geordi: An hour.
Scotty: Oh, you didn't tell him how long it would really take, did you?
Geordi: Well of course I did.
Scotty: Oh, laddie, you have a lot to learn if you want people to think of you as a miracle worker!
