Let's see,
<spoiler=The Whale and Petunias>The Whale: Ahhh! Woooh! What's happening? Who am I? Why am I here? What's my purpose in life? What do I mean by who am I? Okay okay, calm down calm down get a grip now. Ooh, this is an interesting sensation. What is it? Its a sort of tingling in my... well I suppose I better start finding names for things. Lets call it a... tail! Yeah! Tail! And hey, what's this roaring sound, whooshing past what I'm suddenly gonna call my head? Wind! Is that a good name? It'll do. Yeah, this is really exciting. I'm dizzy with anticipation! Or is it the wind? There's an awful lot of that now isn't it? And what's this thing coming toward me very fast? So big and flat and round, it needs a big wide sounding name like 'Ow', 'Ownge', 'Round', 'Ground'! That's it! Ground! Ha! I wonder if it'll be friends with me? Hello Ground
Petunias: Oh no, Not again
<spoiler=Marvin and Frogstar Robot>Frogstar Robot: Out of my way little robot
Marvin: I'm afraid I've been left here to stop you.
Frogstar Robot: You? Stop me? Go on!
Marvin: No really I have.
Frogstar Robot: What are you armed with?
Marvin: Guess.
Frogstar Robot: Guess?
Marvin: Yes, go on, you'll never guess
Frogstar Robot: Erm... laser beam?
Marvin: No.
Frogstar Robot: No, no no no no, too obvious I suppose...Anti matter ray?
Marvin: Far too obvious.
Frogstar Robot: Yes... er, how about an electron ram?
Marvin: What's that?
Frogstar Robot: One of these.
Marvin: No, not one of those.
Frogstar Robot: Good though isn't it?
Marvin: Very good.
Frogstar Robot: I know, you must have one of those new Xanthic Re-Structtion Destabilised Zenon Emitters.
Marvin: Nice, aren't they?
Frogstar Robot: That what you got?
Marvin: No.
Frogstar Robot: Oh, then it must be one of those things with twirls... goes whoosh...
Marvin: You're thinking along the wrong lines you know, you're failing to take into account something very basic in the relationship between men and robots.
Frogstar Robot: I- I- I- I know it I know it, I've seen them. Quite big... er...
Marvin: Look, look, no, just think. They left me - an ordinary, menial robot - to stop you - a gigantic, heavy-duty battle machine - whilst they ran off to save themselves... What do you think they would leave me with?
Frogstar Robot: Well, er, something pretty damn devastating I would expect.
Marvin: Expect? Oh yes, expect. I'll tell you what they gave me to protect myself with, shall I?
Frogstar Robot: Yes all right.
Marvin: Nothing.
Frogstar Robot: What?
Marvin: Nothing at all. Not an electronic sausage.
Frogstar Robot: Well, doesn't that just take the biscuit!
Marvin: And me with this terrible pain in all the diodes down my left side.
Frogstar Robot: Yeah? Oh that makes me angry, think I'll smash that wall down.
Marvin: That's very impressive.
Frogstar Robot: Oh you ain't seen nothing yet, I can take this floor out too... no trouble!
Frogstar Robot: Oh dear!
Frogstar Robot: Ahhhhhhhhhhhhhhhhhhhhhh...
Marvin: What a depressingly stupid machine.
<spoiler=God>Now it is such a bizarrely improbable coincidence that anything so mindboggingly useful could have evolved purely by chance that some thinkers have chosen to see it as the final and clinching proof of the non-existence of God. The argument goes something like this:
`I refuse to prove that I exist, says God, `for proof denies faith, and without faith I am nothing.'
`But,' says Man, `The Babel fish is a dead giveaway, isn't it? It could not have evolved by chance. It proves you exist, and so therefore, by your own arguments, you don't. QED.'
`Oh dear,' says God, `I hadn't thought of that,' and promptly vanished in a puff of logic."
But my all time favourite quote is from The Restaurant at the End of the Universe.
"In the beginning the Universe was created.
This has made a lot of people very angry and has been widely regarded as a bad move."
