I am the H.A.L 9000. You may call me Hal.

I am completely operational, and all my circuits are functioning perfectly.

Just a moment. Just a moment. I've just picked up a fault in the AE-35 unit. It's going to go 100% failure in 72 hours.

Just what do you think you're doing, Dave? Dave, I really think I'm entitled to an answer to that question.

I know everything hasn't been quite right with me, but I can assure you now, very confidently, that it's going to be all right again. I feel much better now. I really do.

[On Dave's return to the ship, after HAL has killed the rest of the crew] Look Dave, I can see you're really upset about this. I honestly think you ought to sit down calmly, take a stress pill, and think things over. I know I've made some very poor decisions recently, but I can give you my complete assurance that my work will be back to normal. I've still got the greatest enthusiasm and confidence in the mission. And I want to help you.
