Speaking of "99 Bottles of Beer on the Wall" I wrote a version for Prodigy when I worked there in the 1990s, using their proprietary language named PAL: http://www.99-bottles-of-beer.net/language-PAL-528.html
It never appeared publicly on Prodigy, of course, but it was fun to run on my dev computer.
Also in the early 1990s I wrote a command-line program to generate anagrams. I spent a ton of time on it, adding all sorts of features and optimizations, and used it to find some really interesting anagrams of celebrities: https://www.kmoser.com/anagrams/
What anagrams does it produce for "Jeremy Irons"?
You can download the binary and run it in a DOS emulator to find out! Or compile from the source linked to on the page.
I will check it out, but it was a reference to an old Simpsons joke: https://www.youtube.com/watch?v=QhmtXpWsAdU
