The fun of watching others work

'I think the most joyous thing in life is to loaf round and watch another bloke doing a job of work. Look how popular the men are who dig up London with electric drills. Duke's son, cook's son, son of a hundred kings—people will stand there for hours on end, with their ear-drums splitting—why? Simply for the pleasure of being idle while other people work.'
