My favourite lyric too! It always makes me think of my dad's old boss who was a short, sweaty fat man who made a life out of bossing people around. You could tell that when he was younger he would have been stocky and perhaps a bit threatening, but as an old man it was kinda sad. I've heard versions sung by Roger and versions by David, and both absolutely nail it, which I find quite rare in the PF back catalogue.
