'Doctor Who': the Forgotten and the Torturous Quiz

Answer: A spring

The spring is faulty, so the switch doesn't automatically spring back. It is thus continually depressed (poor thing), sending the TARDIS further and further back in time. The Doctor explains this to Susan at the end of this superbly unlikely story, using the highly technical prop of a hand held torch. Classic.

Answer: Grasshoppers

The butterflies are known as Menoptra, the ants are Zarbi. The evil bad blob at the centre of the planet is the Animus, and to kill it, one has to point an isotope weapon at its 'dark side'. It sounds like a wonderful multi-layered premise for a story - all very Jungian - but in fact this story is sooo slow-moving and singular, with irritating accents, annoying sound effects, melodramatic overacting, and pantomimic costumes, it is almost impossible to sit through.

There are caterpillars that jump around too (the Optera), but they're mostly in the last episode so you probably won't see them.

Answer: Cyril

Yes, Cyril - all who laugh at him beware! "Cyril hates to lose," says the Toymaker ominously, "so he makes sure that he never does." Stories like this almost make one glad that the BBC archivists got so happy with their video bonfires. The episode that features TARDIS hopscotch is the only one of this story that survives - more's the pity.

Answer: Jamie

Poor Jamie! He nearly meets his death as a result, but then the Krotons realise he can still be of use in giving them information about their star students, the Doctor and Zoe. Meanwhile the Doctor and Zoe have channelled enough intelligence to completely revive the Krotons, who in turn make them feel approved of and clever. "Perhaps the Krotons aren't as bad as we think!" says Zoe, who likes to feel clever. Perhaps this story isn't as bad as we think - it was, after all, written by the wonderful Robert Holmes.

Answer: The Moon

While this story must be congratulated for mentioning Canberra, it is really awfully annoying to listen to that computer voice going on about it. The relay station's location on the Moon makes it a handy target for the Ice warriors, who are from Mars. Anyone who remembers anything else about this story is very clever indeed.

Answer: There are alien ambassadors who look like zombie astronauts

Earth astronauts seemingly return to Earth, but are actually radioactive aliens in disguise. All the aliens want is to communicate with us - they aren't really ambassadors OF DEATH. At least, from memory that's the case...

Answer: TOMTIT

TOMTIT stands for Transmission Of Matter Through Interstitial Time. The other machines mentioned are from perhaps more memorable stories - WOTAN from 'The War Machines', the Keller Machine from 'The Mind of Evil', and BOSS from 'The Green Death'.

Answer: None of these

It's really the best way to remember this story - it's the one where there's no companion. Honestly, what else happens in it? The Doctor is set up, he manages to prove his innocence. That's it. Next!

Answer: Movellans

The Movellans manage to knock the Daleks about a bit with their new Dalek virus. The best thing about this is that it paves the way for 'Resurrection of the Daleks', five seasons later.

Answer: Tegan is from Brisbane, where the Indigenous people are Polynesian not Aboriginal

Polynesians are, of course, indigenous to many places in the Pacific region, but not Brisbane. But the rest of the objections are more than enough to make this event a severe embarrassment for the show. If this moment were removed, it might make this story slightly less torturous.

But as a standout moment for Australian viewers, only a small proportion of whom speak a word of any Aboriginal language, it is almost unforgiveable.

Answer: He wants a slave labour force of Concorde passengers and crew

Oh dear. One can forgive companion Ian getting excited about a cyclotron in 1964 (in 'The Keys of Marinus'); one cannot forgive producer John Nathan-Turner getting excited about a Concorde aeroplane in 1982. This is a really terrible story, famously full of holes, and boring to boot. And to make matters worse, the Master's alias Kalid is one of those embarrassingly awful 'Doctor Who' enemies with an 'east Asian' accent of some description, an 'oriental' costume, and a faux Chinese pseudonym for Anthony Ainley in the credits. Dreadful.

Answer: Omega

Yes. Omega wants to be antimatter. No, hang on, he wants to be the Doctor. He enlists a Timelord traitor's help. Tegan's cousin dies, probably. Or doesn't. The End.

Answer: The Master regenerates

Poor Colin Baker - it wasn't his fault. This story could have been great, a classic saga, but instead... There are some plant creatures. And an exercise bike. The Master makes a token appearance (but does not regenerate, as is clear from his next adventure, 'Survival'). Peri goes bald. Oh, and the Doctor pokes humorous fun at the Valeyard, calling him 'the Graveyard' and such like. Very amusing.

Answer: Red Kangs

"Red Kangs Red Kangs Red Kangs are best!" is of course the famous catch-cry. The Yellow Kangs go extinct, the Blue Kangs turn good at the end when they join forces with the Reds, and Pex, though not a Kang in life, died brave and bold as a Kang should be. I'm sorry - did you want a plot as well?

Answer: An alien baby made a high-pitched scream

Um. Yes. 1959, Welsh holiday camp, according to the BBC website. The other famous bit of trivia about this story is that Sophie Aldred originally auditioned for the role of biker Ray, but was instead cast as Ace, who first appeared in the next story, 'Dragonfire'. But that's not got much to do with 'Delta' really. Oh well.
