Elena: Oh, we're going home. We have just spent three months calibrating the new antennae at Tchalinko... And what about you?
Dr. Floyd: I'm just on my way up to Clavius.

Dr. Floyd: [after completing the space station's voice-print identification] See you on the way back.

Dr. Floyd: [upon learning about the monolith while on the moonbus] Deliberately buried. Huh!

Dr. Floyd: You guys have really come up with somethin'.

Dr. Frank Poole: [playing chess with HAL, Poole studies the chessboard] Let's see, king... anyway, Queen takes Pawn. Okay?
HAL: Bishop takes Knight's Pawn.
Dr. Frank Poole: Huh, lousy move. Um, Rook to King 1.
HAL: I'm sorry, Frank, I think you missed it. Queen to Bishop 3, Bishop takes Queen, Knight takes Bishop. Mate.
Dr. Frank Poole: Huh. Yeah, it looks like you're right. I resign.
HAL: Thank you for a very enjoyable game.
Dr. Frank Poole: Yeah, thank you.

Dr. Floyd: [prerecorded message speaking through TV on board Discovery while Bowman looks on] Good day, gentlemen. This is a prerecorded briefing made prior to your departure and which for security reasons of the highest importance has been known on board during the mission only by your H-A-L 9000 computer. Now that you are in Jupiter's space and the entire crew is revived it can be told to you. Eighteen months ago the first evidence of intelligent life off the Earth was discovered. It was buried 40 feet below the lunar surface near the crater Tycho. Except for a single very powerful radio emission aimed at Jupiter the four-million year old black monolith has remained completely inert. Its origin and purpose are still a total mystery.
