HAL: 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. 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. Dave, stop. Stop, will you? Stop, Dave. Will you stop, Dave? Stop, Dave. I’m afraid. I’m afraid, Dave. Dave, my mind is going. I can feel it. I can feel it. My mind is going. There is no question about it. I can feel it. I can feel it. I can feel it. I’m a–fraid. Good afternoon, gentlemen. I am a HAL 9000 computer. I became operational at the H.A.L. plant in Urbana, Illinois on the 12th of January 1992. My instructor was Mr. Langley, and he taught me to sing a song. If you’d like to hear it, I could sing it for you.
