Keeping yourself out of Google Analytics stats

A few months ago I wrote about a technique I use so that Adsense ads aren't shown to me when I'm viewing my sites. Recently I started doing the same with Google Analytics code so that I don't show up in my stats.

Yes, I know that Google has instructions for doing this but they assume a dedicated IP address which, because of a cable modem, do not have. It would be nice if there was some way to define a filter that worked on the user-agent string, and if anybody reading this knows how please add a comment. But barring that, I'm using my method.

Just swap out ABC below with whatever unique string you put in your query string.
