First (and probably last) time I've ever said this, but I agree with Biohazard.
It's not so much the fact half the Internet has already seen it (a month or so back when it was originally conceived it was a front-page story on Digg.com, since then it has been posted on here at least four times), it's the way the OP posted it. He doesn't cite a source, he just gives us the code and instructs us on what to do, leading those who haven't already seen it to assume that he had some part in creating the code – leaving himself open to praise is something which I certainly don't agree with given the circumstances.
Then there's the title of the thread. Superfluous capitalised letters, overuse of exclamation marks and the claim that it is an "IE trick" – as someone else has already mentioned, it works in other browsers. It's not really a "trick," either, it's just a piece of Javascript which, when executed, affects objects on a page.
