Oysters

You start with an oyster. You put it inside a large olive. Then you put the olive inside an ortolan (a wee bird called ‘the garden bunting’, in case you are among the underprivileged), and the ortolan inside a lark, and so on and so on. In the end you have a roasted oyster. Or perhaps a social revolution.
