The Making of the Hitchhiker's Guide to the Galaxy

Way, way back in a time almost lost to history and now known only as Monday the 5th of January 1981 the BBC screened the first episode of the TV adaptation of the book adaptation of the radio show adaptation of the thoughts of a bloke called Douglas.

Douglas was a clever man and like all the best types of clever men he knew that some clever things were also funny things and so set about making a funny thing out of the clever things.  In order to do this he drafted in some other clever people.  Some who were clever at organising, some who were clever at drawing, some who were clever at filming or recording or building or musicing or pretending to be someone else.

Then, 10 years later, someone else who was clever had a clever idea to take all the extra bits that the clever people had filmed, film some new bits of some of those self-same clever people and get the main clever pretending man to talk about how clever everyone was.  They even had the idea to put two different spaceships at the beginning to make less clever people who really like watching clever people at work go "Yay!" like the big geeky kid that he is they are.
