Young Ned Seagoon, walking the streets of London during a particularly thick 'pea-souper,' accidentally knocks over a Miss Selina Clutch. Her strange behaviour mystifies young Neddie until a chance meeting with Dr. Rheingold Fnutt puts him on the track of an underground terrorist organisation led by the reckless 'Overcoat Charlie' intent on wrecking the capital's commercial life by blanketing London with an artificial foreign fog that makes people think nothing but the best of each other. Professor Crun is called in by the Government to find an antidote to 'Forog' but not before Professor Moriarty and Commercial Attache, Grytpype-Thynne, nearly succeed in bringing London life to a standstill.

So runs the synopsis to this week's edition but as is usually the case the actual show itself bears little relationship to Spike Milligan's fevered precis. Instead, we find an increasingly manic Ned Seagoon hell-bent on solving London's fog problem, conversing with statues and getting all xenophobic over atmospheric conditions.

Joining Tyler this week is James Page who loves Forog... but can our host say the same?
