Here's what Terry Pratchett said about it (in a footnote) in The Science of Discworld II - The Globe:
"Lord Vetinari, the Patrician and supreme ruler of the city, took proper food labelling very seriously. Unfortunately, he sought he advice of the wizards of Unseen University on this one, and posed the question thusly: 'Can you, taking into account multi-dimensional phase space, meta-statical anomaly and the laws of probability, guarantee that anything with absolute certainty contains no nuts at all?' After several days, they had to conclude that the answer was 'no'. Lord Vetinari refused to accept 'Probably does not contain nuts' because he considered it unhelpful."
Heheheheheh.
Oh, and I think they are advising against pulling UFOs into bridges. You might inadvertently trigger an interstellar war that way, and Ford doesn't wish to have to pay for all the dead soldiers, destroyed aircraft and nuked cities. |
