Series 5, Episode 4

This week John looks at the rising problem of cellophane. He also meets a man in the street who takes a dim view of electricity, along with a porcupine called Ronald who emits squeaking noises (the two may be related). Plus catch up with the show's free-falling producer Richard Cray as he spends a welcome break in hospital. Why not send him hard-boiled eggs or nuts, or some such? (The two may be related.) Yes, it's all here - but why? And should it really be somewhere else? Find out, if you can, in this, the Year of the Plinth.
