How can the concept of 'riff * raff' be distinguished from simple randomness?

While seemingly random, the 'riff * raff' isn't purely chaotic. It possesses a certain *pattern* to its chaos – a cosmic humor or irony. It's not just things happening at random; it's things happening in a way that's unexpected, often absurd, and frequently interconnected. It's randomness with a narrative intent, a cosmic joke being played out on a grand scale.
