He found notoriety as K-Fed, then Fed-Ex, the loser (ex-)husband who dragged down sweet little Britney Spears for so long ... but my, how the tables have turned. While bald Brit languishes in rehab, Kevin Federline is parlaying his unsuccessful rap career into a new venture.

He's launched a search engine.

That's right, every time you Search with Kevin (search toolbar and plug-ins available for Firefox and IE7) this month, you go in the draw to win amazing prizes, such as a Kevin Federline Autograph, or tickets to Kevin's private birthday party in Las Vegas (travel not included).

We strongly urge you to point your search box in the direction of Click4theCause for the remainder of the month, instead. A collaboration between the United Nations High Commissioner for Refugees and Microsoft, whenever you search using Click4theCause, Microsoft will throw wads of cash at the ninemillion.org campaign.

Nine million? Ninemillion.org helps the nine million children in the world who are refugees. Nine million! That's even sadder than Britney's descent into tubby madness.

Microsoft's donations go towards providing education for some of those nine million child refugees. That URL again: Click4theCause. Go there right now and spend five minutes searching for "fdsafdsafs", "jkl;jhhfoais", or even "britney spears". It will make you feel good.
