Listing to Port

1. A pie approximately the size and shape of a pie shop, having a rather convincing false shopfront and a well-hidden pastry lid; the point of which being to lure in unsuspecting hopeful pie-eaters and trap them inside, so that they can be released on the ceremonial cutting of the pie rather like the four-and-twenty blackbirds in the nursery rhyme.
2. A pie that has no bottom. Not one that has no pastry bottom: there are plenty of those. I mean a pie that literally has no bottom, you break through the top and find yourself looking down into a horrifying abyss.
3. A pie containing a smaller pie containing another smaller pie, for pastry lovers everywhere.
4. A giant space pie constructed by aliens around a star, the intent being to harness the entire energy of that star to gently cook the pastry over some billion years or so; the gastronomical version of the Dyson Sphere. There are in fact three of these currently detectable with current telescope technology, but it will take science a few years to come round to the correct explanation of what we are seeing.
5. The lifesaving pie suits of the Cornish pixie folk, which inflate around their owners in times of trouble to provide a convincing facsimile of a particularly unappetising Cornish Pasty; the intent being that, rather than throwing a wobbly about having discovered a pixie, the offending human will instead consign the suspect pasty to a local bin, from whence the pixie can later crawl under cover of darkness and escape.
6. Nautical pies which can be eaten if necessary but which will also stay afloat for long enough that you can paddle all the way to that distant island with your large spoon, provided you are OK with sitting in gravy.
7. Your pie, made precisely for you in just the way that you like best; there is only one of it so exactly correct, and after you have eaten it you will feel oddly content, but you will never go out seeking pie again and perhaps there will be less of a sparkle in your eye for the rest of your days.
