Back when https://xkcd.com/1930/ was posted, I made a regular expression to create a generator using a regex sampler (for instance http://dwickern.github.io/regex-sample/ ).

I've put the regex at https://gist.github.com/kmill/17c5ef4f99bd9ef7ad799f0b487448...

The amusing thing to me is that this regex visualizer can reproduce the comic.
