What gets us into trouble is not what we don't know, it's what we know for sure that just ain't so. -Mark Twain
On Earth, man had always assumed that he was more intelligent than dolphins because he had achieved so much - the wheel, New York, wars and so on, whilst all the dolphins had ever done was muck about in the water having a good time. But conversely, the dolphins had always believed that they were far more intelligent than man - for precisely the same reasons. -HHGTTG
Anything that can go wrong will and anything that couldn't possibly go wrong in a million years will have a darn good try.
