"Whatever blows can be sucked."

Not The Creature From The Pit this time but a story which could be said, in American vernacular, both to 'blow' and to 'suck'.

It's Underworld - a production so maligned that even most of the sets refused to participate. A CSO mother lode in which Minyans are led by Minions, the proletariat dine on the very rock they mine and gravity does precisely whatever the hell it likes.

Meanwhile, Gwyneth Paltrow gets a drastic makeover, Mr Dors takes it lying down and Leela takes a fancy to a bit-part with a Rohypnol ray. Chuck in some deaf-blind guards, hordes of bored extras and some rather louche lift music and it really does feel like we're descending to rock bottom.

So 'the quest is the quest' but will Jim and Martin see Underworld as a golden moment in Who mythology or will they end up feeling fleeced?

Listen in to find out.

"If anything happens, let me know."

What do you get if you have two episodes to fill with no guest actors and no new sets?

Well in the weird world of Lime Grove 1964, you get The Edge of Destruction - a veritable cryptic crossword with clues from another, different cryptic crossword.

This is, of course, the one where Susan turns sinister scissor sister, Ian seems to have been at the TARDIS brown ale, the Doctor - even with a head wound - still wins Gallifrey's Fastest Butler, and poor old Babs has to hold it all together, despite her pathological fear of Salvador Dali.

Even the Fornicator can't help them as they try to discover what the heck is going on (and what the writer has been smoking) until, finally, the solution springs to mind.

So can Jim and Martin make sense of the sentient ship's clues or will the story leave them on the edge of nervous destruction?
