Can someone explain this to me?

I came across this link as a listing in some obscure PPC engine.

www.google.com/url?q=http://www.widgets.com/widgets/google.htm&sa=l&ai=AIrHgXFdp-MdlUkstss4KJjaEDjfyBkKtCXgAIktTAA_5qFACIgpF&num=8

Of course, the link displayed was www.widgets.com but I noticed something was up when I clicked it, so I copied the address with a right click.

What exactly is going on with this link?

Looks like an AdWords url to me?
