"Google won't search for Chuck Norris... because it knows you don't find Chuck Norris, he finds you."
Well, I like to give credit where credit is due, so I did some research (like I always do) and found a little trail of sorts. Seems Mark's page probably got if from the SEO Blog, by Jim Hedger , who in turn got it from Google PR-czar David Krane at http://www.kraneland.com/ .
Whew! Anyways, here is what you do:
Step 1: Visit http://www.google.com/
Step 2: Input these search terms: find chuck norris
Step 3: Click "I'm feeling lucky"
Then check out the results!
