I am a private detective. I am paid to be inquisitive and presumptuous.

It is known that there are an infinite number of worlds, simply because there is an infinite amount of space for them to be in. However, not every one of them is inhabited. Therefore, there must be a finite number of inhabited worlds. Any finite number divided by infinity is as near to nothing as makes no odds, so the average population of all the planets in the Universe can be said to be zero. From this it follows that the population of the whole Universe is also zero, and that any people you may meet from time to time are merely the products of a deranged imagination.

Just believe everything I tell you, and it will all be very, very simple.' Ah, well, I'm not sure I believe that.

The switch had two settings. You could either turn it to AUTO, in which case the awning lowered itself whenever the sun came out, or you could set it to MANUEL [sic], in which case, we assumed, a small, incompetent Spanish waiter came and did it for you.

Human beings, who are almost unique in having the ability to learn from the experience of others, are also remarkable for their apparent disinclination to do so.

The kakapo is an extremely fat bird. A good-sized adult will weigh about six or seven pounds, and its wings are just about good for waggling a bit if it thinks it's about to trip over something - but flying is out of the question. Sadly, however, it seems that not only has the kakapo forgotten how to fly, but it has forgotten that it has forgotten how to fly. Apparently a seriously worried kakapo will sometimes run up a tree and jump out of it, whereupon it flies like a brick and lands in a graceless heap on the ground.

If there's any real truth, it's that the entire multidimensional infinity of the Universe is almost certainly being run by a bunch of maniacs.
