Mm, reminds me of the old world of IRC. I still remember fondly when I asked for help installing FreeBSD, and got banned with a message of “try linux”.

So I did, never looked back. (Until I got a Mac at least, which counts as a BSD.)

For real though, the shortest license is probably the WTFPL:

0. You just DO WHAT THE FUCK YOU WANT TO.

Might’ve used it a couple of times myself.
