In a pig's earWhy did that phrase pop into mind just now? Pigs might fly?
As it happens I am this very moment eating sliced pig's ear (which I do quite regularly, with relish - nothing to do with chutney!). 'In a pig's ear' I see is largely UK/OZ usage meaning 'not bluddy likely!'
Well as it happens, in a pig's ear there is gelatinous skin and cartillage; it is served cold soused (pun intended) in oil and soy sauce I guess, with shredded shallot and shredded carrot, maybe some dill too.
But I have forgotten why it popped into mind - probably something preposterous written here!
