Sherlock Holmes and Dr Watson are camping together. When they go to sleep, Sherlock says, 'Tell me what you can see when you're looking up?'
'Thousands of stars,' says Watson.
'And what's your conclusion from all this?'
Dr Watson starts to think. 'If I consider it from astrological aspects,' he says slowly, 'I must assume that there are millions and millions of stars and galaxies in the universe. From psychological points of view I conclude that we're so infinitely small in comparison with God's overall creation. And if meteorology is concerned, I would say that we can expect fine weather tomorrow. What's your opinion?'
'You're a fool, Watson,' Holmes says. 'Our tent has been stolen.'
