KIRK: Have fun kids, but not too much fun. It'd be crazy to try to raise children on a starship exploring deep space. Heh heh, just kidding.
KIRK: Captain to Bridge. It's the 23rd century, why are we still communicating with the intercom from a 1990s apartment building?
Kirk and Spock catch each others' eyes on the bridge, and think whistfully of what could have been, if only they weren't coworkers.
UHURA: Aren't you scared?
SULU: Kirk is about to talk the bad guy into blowing up his whole invasion fleet.
UHURA: How the f*** does he do that?!
A rare clip from the never-aired season three episode, 'Spock Does Inventory'.
