I had been going to announce that I was working something intentionally ridiculous as an April Fool, however I cannot think of something that is ridiculous enough to place it outside the realms of possibility.
How about the one where it's set totally in the skies above pre-historic Earth and we remember to destroy each location as we leave?
Or the one where the Sixth Doctor communicates with giant insects by squawking at them, becomes involved in a bar fight, becomes involved in the French Revolution and meets Mrs Thatcher?
Or the one where (almost) everyone has lots of sex?
Or even the one with Krotons in the soup?
See what I mean?
