As known, I've recently moved. This triggered series of celebrations of the new place, and I received various gifts. It's common for people to bring chocolate or wine (especially when they don't know what to bring,) but AO was original and brought a huge salad. This reminded me of a story about another salad (no connection).
It's said to be from the folklore of [censored] military intelligence unit. The idea of the Fibonacci series was used by their kitchen to make the so-called Fibonacci salad which they used to serve every day. The recipe is to take yesterday's salad and add to it the one of the day before yesterday.
(While writing this, I decided to look up google and discovered that there is a real thing named Fibonacci salad)
