I think that a good starting place to explain the concept to people would be to describe a Travesty Generator. I remember playing with one of those back in the 1980’s. If you fed it a snippet of Shakespeare, what it churned out sounded remarkably like Shakespeare, even if it created brand “new” words.

The results were goofy, but fun because it still almost made sense.

The most disappointing source text I ever put in was TS Eliot. The output was just about as much rubbish as the original text.
