Yeah I have an SSH daemon running on the default port at funky.nondeterministic.computer for people to hit, but it's mostly bots, which is no fun.
Some time ago I did a little experiment by running `nc -l -p 23` (telnet) which connects the next incoming telnet connection to your console. Type in a simulated prompt like Password: or # and it'll be buffered until the connection comes in. Then see what the scanner sends.
It’s too bad that ssh doesn’t carry sound. A MIDI-style rendition of the song would really tie it all together.
