I once spent a drunken friday night helping my partner analyse her job in uml.

She also maintains that I think the world was made in perl, to which the only possible answer is that it can't have been - it wouldn't have taken 7 days :-)

Possibly even scarier, I once debugged a colleagues regex over lunch, without the aid of PC, paper, or pen. We sat there for half an hour saying things like: 's slash tilde backslash s curly bracket 4 close curly bracket backslash w plus.....'. We got a few odd looks, to say the least.
