There’s a picture in The Third Ladybird Book of Nursery Rhymes of a small, nervous boy in knickerbockers appearing before a man of authority: ‘I do not like thee, Doctor Fell,/ The reason why, I cannot tell./ But this I know and know full well,/ I do not like thee, Doctor Fell.’ It’s a curious little thing, but somehow very pleasing. It rhymes, there’s a clear, easy rhythm behind the words and we’re familiar with the sentiment. In short, it’s a typical nursery rhyme.
