Chapel: Spock, what are you doing in my quarters?
Spock, startled: Oh.. uh.. I wasn't sniffing, wearing, or rubbing all over my naked body your underwear.
Chapel: WHAT!!
Spock: You hear that alarm? I better get to the bridge!
Chapel: What alarm?
Spock: Got to go!
Chapel: What the hell did you do wipe your face with a grilled cheese sandwich, Doctor?
McCoy: For some odd reason most of the women on the ship are suffering from peroxide poisoning and I can't figure out why.
Scotty: I'll never tell!
Kirk: If you don't tell me I'm going to start farting in this air tight room. I've had Taco Bell so they should be very loud and very smelly. The kind of smell that you can taste.
Everyone else in room: FOR THE LOVE OF GOD TELL HIM!
Kirk: There's you, me, your balls, and this drawer, Mr. Scott.
Kirk: What do you mean by the word "is"?
