Right. Let's start the renewed blogging with a small pseudo-psycho-test. These seem to be all the rage on certain unmentioned social networking sites.

Look at the picture attached to this post. Which reaction is it most likely to produce in your brain?

1. Ooh, a café. I think I'll go have a cuppa.
2. That certainly is a large amount of punctuation
3. Hold on a sec, this regex will never work.

If you chose number 3, I don't have to explain anything. If you didn't, you wouldn't understand even if I did. If you say “What? There's no negative lookbehind assertion in this regex”, you'd be absolutely right, of course.
