Guinan: I hear they drummed you out of the Continuum.
Q: I like to think of it as a significant career change.
Guinan: Just 'one of the boys', eh?
Q: One of the boys with an I.Q. of two thousand and five.
Data: The Captain, and many of the crew, are not yet convinced he is truly human.
Guinan: Really? [Picks up a fork and stabs Q's hand.]
Guinan: Seems human enough to me.
McCoy: How old do you think I am anyway?
Data: 137 years, Admiral, according to Starfleet records.
McCoy: Explain how you remember that so exactly.
Data: I remember every fact I'm exposed to.
McCoy [looking at Data's ears.]: I don't see no points on your ears, boy, but you sound like a Vulcan.
Data: No, sir. I'm an android.
McCoy: Hmm...almost as bad.
