No poet or scholar, I; but my natural impulse would be to read the line not simply as a pleasant piece of alliteration, but also as an intentional, witty double meaning. Master Langland’s was, after all, a more powerful, well-read intellect than many (on the other hand, I wouldn’t be the first person to read into a line of verse more than the poet intended).
---- Thanks, aldi. But the fact is, I was too pretty (blue eyes, curly hair, long eyelashes, believe it or not) to be a vulgar, Max Miller type comic (the kind I’m best qualified to be). Had to settle for an almost serious technical career, with scatology as a fun sideline ;-)
I love the expression “marching together”. Slipping it in is a great way to cause confusion, when the conversation gets tedious and boring.
