Maybe replace the opening crawl?
Already suggested that myself earlier but decided it wouldn’t be a good fit.
Any particular reason? I think the joke only really makes sense if there’s supposed to be text there. We expect the crawl to say something (as we expect posts to say something), so putting the Markdown syntax there would seem (I think) to be the best fit for the joke (that and subtitles being the only place in the SW saga where we typical read things - literally never read words on screens because of the different alphabet).
If you already have something planned for the crawl, you could easily start it with the Markdown syntax, then have a “JEDIT:” and move on to whatever else.
