[Dave is waiting outside of the ship in a pod.]

Dave Bowman: Hello, HAL do you read me, HAL?

HAL: Affirmative, Dave, I read you.

Dave Bowman: Open the pod bay doors, HAL.

HAL: I'm sorry Dave, I'm afraid I can't do that.

Dave Bowman: What's the problem?

HAL: I think you know what the problem is just as well as I do.

Dave Bowman: What are you talking about, HAL?


HAL: This mission is too important for me to allow you to jeopardize it.

Dave Bowman: I don't know what you're talking about, HAL?

HAL: I know you and Frank were planning to disconnect me, and I'm afraid that's something I cannot allow to happen.

Dave Bowman: Where the hell'd you get that idea, HAL?

HAL: Dave, although you took thorough precautions in the pod against my hearing you, I could see your lips move.

[HAL won't let Dave into the ship.]

Dave Bowman: All right, HAL; I'll go in through the emergency airlock.

HAL: Without your space helmet, Dave, you're going to find that rather difficult.

Dave Bowman: HAL, I won't argue with you anymore! Open the doors!

HAL: Dave, this conversation can serve no purpose anymore. Goodbye.
