This lecture may be from 1991, but the topic is timeless, the
discussion is lucid, and it's all delivered by Basil Fawlty
himself. Here's 36 minutes of John Cleese discussing the
psychology of being creative. Listen to one of the funniest
fellows alive talk seriously about how to become more creative,
how to spitball ideas with others, and the benefits of building
a "space-time oasis." Comedy sketches about dead parrots don't
grow on trees, after all.  [Via MeFi]
