Peter Davison, who provides the voice of the Dish of the Day in this episode, was about to take up the role of the Doctor in Doctor Who. He remained as the Fifth Doctor from 1981 to 1984.
When our heroes are standing in Milliways early in the episode, a stagehand who provides Zaphod's third arm can be clearly seen crouching behind Mark Wing-Davey (Zaphod).
Zaphod: Listen, Ford, everything's cool and froody.
Arthur:You mean, everything's under control?
Zaphod: No, I do not mean everything's under control. That would not be cool and froody. If you want to know what happened, let's just say I had the whole situation in my pocket. Okay?
Dish of the Day: Good evening, madame and gentlemen. I am the main dish of the day. May I interest you in parts of my body? May I urge you, sir, to consider my liver? It must be very rich and tender by now. I have been force feeding myself for months.
Arthur Dent: Green salad, please.
Dish of the Day: A Green salad?
Max Quordlepleen: Believe me, ladies and gentlemen, there is nothing penultimate about this one. This, ladies and gentlemen, is the proverbial it. After this, there is void... emptiness... oblivion... absolute nothing. (dramatic pause) Except, of course, for the sweets trolley and our fine selection of Aldebaran liqueurs. And for once, ladies and gentlemen, there is no need to worry about having a hangover in the morning, for there will be no more mornings.
Max Quordlepleen: And lastly, a party of devout believers from the Church of the Second Coming of the Great Prophet Zarquon. Still waiting for the Second Coming? Well, fellows, let's hope he hurries. He's got eight minutes left. (Laughter) No, but seriously, no offense meant. I know one shouldn't make fun of deeply-held beliefs. So, I think, a great big hand for the Great Prophet Zarquon (applause) - wherever he's got to.
Marvin: The first ten million years were the worst. And the second ten million: they were the worst, too. The third ten million I didn't enjoy at all. After that, I went into a bit of a decline.
Max Quordlepleen: And now, ladies and gentlemen, the moment you've all been waiting for. The skies begin to tremble, nature collapses into the streaming void. In fifteen seconds' time, the universe itself will be at an end. See where the light of infinity bursts in upon us.
Zaphod Beeblebrox: Hey, Ford. How many escape capsules are there?
Ford Prefect: None.
Zaphod Beeblebrox: You counted them?
Ford Prefect: Twice.
Marvin: Did I say something wrong? Sorry, pardon me for breathing - which I never do anyway, so I don't know why I bother to say it, oh God I'm so depressed.
Zaphod Beeblebrox: You mean they want to arrest me over the phone? Could be. I'm a pretty dangerous dude when I'm cornered.
Ford Prefect: Yeah. You fall to pieces so fast that people get hit by the shrapnel.
Zaphod: What is this, Judgement Day?
Arthur: Oh, do we get to see that too? Terrific.
Book: (introducing the program) And this computer, which was called the Earth, was so large that it was frequently mistaken for a planet - particularly by the strange ape-like beings who roamed its surface, totally unaware that they were simply part of a gigantic computer program. And this is very odd, because without that fairly simple and obvious piece of knowledge, nothing that ever happened on Earth could possibly make the slightest bit of sense.
Book: The Universe: some information to help you live in it. Area: infinite. Population: none. It is known that there is an infinite number of worlds, but that not every one is inhabited. Therefore, there must be a finite number of inhabited worlds. Any finite number divided by infinity is as near to nothing as makes no odds, so if every planet in the Universe has a population of zero then the entire population of the Universe must also be zero, and any people you may actually meet from time to time are merely the products of a deranged imagination.
Douglas Adams himself scrawled the various number 42s on the wall of the Atomic Fallout Shelter on Jikthroom Beta.
Peter Davison, the voice of the Dish of the Day, was married at the time to Sandra Dickinson, who plays Trillian.
Book: If you've done six impossible things this morning, why not round it off with breakfast at Milleways, the Restaurant at the End of the Universe?
In Lewis Carroll's book Through the Looking Glass, Alice says "One can't believe impossible things", and the White Queen replies - "I dare say you haven't had much practice. When I was your age, I always did it for half an hour a day. Why, sometimes I've believed as many as six impossible things before breakfast."
