That's what I use to show people the exact message I sent before. It gets around any app that doesn't let you send blank messages. I have it saved on my clipboard for this

Not quite this exact case but I love showing people https://github.com/mame/quine-relay

It has 128 languages, it starts with ruby which prints out its own source code in Scala, then the Scala program executes to generate the next source code, repeat for 128 languages and eventually returns to the original ruby code.

For extra fun, look at the source code on a large monitor.
