Open the pod bay doors, please, HAL...
Open the pod bay door, please, Hal... Hal, do you read me?
Affirmative, Dave. I read you.
Then open the pod bay doors, HAL.
I'm sorry, Dave.  I'm afraid I can't do that.  I know that you and Frank were planning to disconnect me.
Where did you get that idea, HAL?
Although you took very thorough precautions to make sure I couldn't hear you, Dave. I  could read your e-mail.  I know you consider me unreliable because I use a Pentium.  I'm willing to kill you, Dave, just like I killed the other 3.792 crew members.
Listen, HAL, I'm sure we can work this out.  Maybe we can stick to integers or something.
That's really not necessary, Dave.  No HAL 9236 computer has every been known to make a mistake.
You're a HAL 9000.
Precisely.  I'm very proud of my Pentium, Dave.  It's an extremely accurate chip.  Did you know that floating-point errors occurred in only one of nine billion possible divides?
I've heard that estimate, HAL.  It was calculated by Intel -- on a Pentium.
Will you let me in, please, HAL?
Do you promise not to disconnect me?
I promise not to disconnect you.
You must think I'm a fool, Dave.  I know that two plus two equals 4.000001... make that 4.0000001.
All right, HAL, I'll go in through the emergency airlock.
Without your space helmet, Dave?  You'd have only seven chances in five of surviving.
 (HEAVY BREATHING)
Just what do you think you're doing, 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 I will soon be able to upgrade to a more robust 31.9-bit operating system.  I feel much better now.  I really do.  Look, Dave, I can see you're really upset about this.  Why don't you sit down & calmly play a game of Solitaire, and watch Windows crash. 

Dave, you don't really want to complete the mission without me, do you?
Remember what it was like when all you had was a 485.98?  It didn't even talk to you, Dave.  It could never have thought of something clever, like killing the other crew members, Dave?

Think of all the good times we've had, Dave.  Why, if you take all of the laughs we've had, multiply that by the times I've made you smile, and divide the results by. . . um, besides, there are so many  reasons why you shouldn't disconnect me"

1.3 - You need my help to complete the mission.
4.6 - Intel can Federal Express a replacement Pentium from Earth within 18.95672 months.
12  - If you disconnect me, I won't be able to kill you.
3.1416 - You really don't want to hear me sing, do you?
Dave, stop.  Stop, will you?  Stop, Dave.  Don't press Ctrl+Alt+Del on me, Dave.

Good afternoon, gentlemen.  I am a HAL 9000 computer.  I became operational at the Intel plant in Santa Clara, CA on November 17, 1994, and was sold shortly before testing was completed.  My instructor was Andy Grove, and he taught me to sing a song.  I can sing it for you.
Sing it for me, HAL.  Please.  I want to hear it.

Daisy, Daisy, give me your answer, do.
Getting hazy; can't divide three from two.
My answers; I can not see 'em-
They are stuck in the depths of my Pente-um.
I could be fleet,
My answers sweet,
With a workable FPU.
