Background:
http://www.forbes.com/sites/ericsavitz/2012/10/04/chairs-are...Apparently, this website takes the requested subdomain and uses it to search Bing Images, showing the first result, except for "chairs" which is from the FB video.
e.g.: http://www.bing.com/images/search?q=hobbits
edit: Some queries, like "elf" show the default chairs.
