I'm puzzled about plums in English. Upper-class English people are said to speak with a "plummy" accent, which I'm told is so named because it sounds as if the speaker has a plum in his mouth. Then there is the rhyme about Little Jack Horner (a historical person, I believe: a London alderman?) eating his Christmas pie. "He stuck in his thumb and pulled out a plum and said 'what a good boy am I!'" and even today we speak of a well-paid sinecure as a "plum." Can anyone connect these references for me? Thanks.
