I use bits of song titles from the 80s or 90s - started with naming a dev server "Hammertime" (no-one else had any reason to use it, so "u-can't-touch-this") and itslikethat and halfwaythere followed along. I had quite a few names lined up at one point. At present "iwontdothat" won't - its off, although Hammertime is also stopped so a name doesn't guarantee character.
