Firstly, open your favorite web browser, then go to Google Search homepage, type Google Chuck Norris into the middle search box, then press I’m Feeling Lucky button. Now, let’s see what search result do you get?
Yup, no search results because no standard web pages containing all your search terms were found, due to the fact Google won’t search for Chuck Norris because it knows you don’t find Chuck Norris, he finds you.
Whatever, the actual fact is that you’re been brought to this
spoof web page (no longer valid) directly, which has the style pretty similar to Google search results page. The funny effect actually existed since more than a year ago. Unfortunately whoever creates the trick can’t manage to trick the term “Chuck Norris” itself on Google.
Update: The trick is now commonly known as Google Bomb and no longer works.
