Reminiscent of the ebay ads that would come back with 'find $query on ebay now' where $query would be anything you typed into the google search box (the early days of the adsense API).
It didn't take very long before some very embarrassing screenshots surfaced.
And before that it was Amazon. I still remember the "find it on Amazon" link on every page of AOL NetFind search results :) Apparently it was some special deal they made with AOL, from back when search engines did things like that: http://www.timewarner.com/corp/newsroom/pr/0,20812,666067,00...
