My favorite is pokeglitch. Otherwise this is before my time, I've never seen 93/95/98 (my elementary school had machines running 2000 and DOS, though).
One of my former employers was using DOS not that many years ago (well after 2000), using Novell netware for networking. I wrote a backup program (glorified xcopy script) for it, automatic patching (autoexec.bat called a script on the network drive), and a few other things.
