File this one under the ingenius section. If you like dirty movies and sites, or even if you don't, you still may be able to appreciate the silliness behind Booble- the Google of Adult search engines.

Sure, Booble doesn't have a large index, but a search for an adult star's name may give results of sites that sell a paid subscription service to their content. An unnamed New York-based former internet executive has pumped his own money into the new website that has styled itself as a light-hearted parody of the world's largest and best-known search engine, Google.com.

"What was a bit fun and a joke became a business. People like it. It makes people smile. It's funny and I think it'll grow," the man in his mid-40s said.

The adult sites to which Booble users will be directed have been filtered to exclude illegal or extremely hard-core material, using criteria including whether a site is worth the price it charges viewers and the quality of its images. I'm sure each site indexed in Booble's search database is linked to the site's affiliate program. If Google doesn't sue the living hell out of these guys, they may even get to sell some ad space on the site. Will they keep the theme going and do a porno version of AdWords?
