There's so much to say about this wonderful, brilliant lecture by Hitchhikers Guide To The Galaxy author Douglas Adams, but I'm not going to spoil any of it. Just get through the first 10 minutes or so and you'll find it almost impossible to stop listening. I had to tear myself away from it at 3am, and the first thing I did on rising at 7am was go straight back to it. As soon as work is done, I'm watching it again.

Enjoy fellow twig enthusiasts!
