Back at Uni we got four new workstations so obviously I named them 'death', 'war', 'famine' and 'pestilence'. Then shortly after we added a fifth, it ended up being 'mayhem'.*

Some time later we got two more boxen and the female members of our research group were given the job of naming them, and we ended up with 'itchy' and 'scratchy'...

* for the Pratchett readers I was wrong, it should of course have been 'Kaos'...

Personally — since we're all chiming in — I use elements. My fallback DNS is a periodic table.
